Nick has been very helpful in helping me diagnose a problem with a XBR-65X750. We are still trying to pin down the issue but I have no hesitation to recommend Nick. 5 star service...
Hi Nick I have a XBR 65Z9D with a 8-blink power on problem then nothing, it will not display anything. I have replaced the main and power board, the original problem was half white screen and half black. I know my connections and replacements of the items were also done correctly as I have worked on thousands of professional items. Where do I go from here, thanks Brian.
If the replacement mainboard is giving you 8 blinks, then you most likely received a none working mainboard. 8 blinks is indicative of a failed mainboard. Return it and get a new one.
Turn the lights off in the room, and make it as dark as possible. Now turn on your TV. Do you get a glow from the screen? If yes then that means your LEDs are good and turning on. However, it also means you may have a bad screen. If no glow then your LEDs are not turning on although that doesn't mean they are bad, perhaps they aren't getting power or the turn-on command. If this is the case you may have a bad mainboard. Something you can do in that case is shining a flashlight onto the screen, do you see the image very faintly? If yes then that would mean your LEDS are most likely bad which for this set they are imbedded in the screen so it means buying a new TV. If not then I would suggest a new mainboard. Please keep in mind this is not a proper diagnostic, this is based on my own opinion what I think are the most likely reasons for the set to have gone bad and are purely speculation. If you would like for us to help you further with diagnostics, we do have a testing and diagnostic service where you can mail in some of your circuit boards which we can live test in our system in our shop at a $20 bench fee per board. Our contact info is in the video description if you have more questions.
Do you have information or a video for 3 red blink code for the Sony XBR-65X900C? This model has a Power Supply Board APDP-330A1 & Sub Power Supply Board APDP-180A1
Hello Jason. One of the reasons we haven't covered the 3 red blinks is because of how rare it is. According to the service manual, a 3 blink code is due to a faulty mainboard. While it is not common, I do believe we have actually serviced that fault by replacing the HDMI processor IC. It's the large IC chip next to the HDMI ports with 200 pins or so. If you want to send it in for repair, we can replace that chip.
Hi Nick. The picture on my XBR-55X900F froze in the middle of a film (on Prime, not DVD) and when the unit would not respond to any command from the remote, I unplugged it (something I have found myself having to do with increased frequency in recent months). Usually this solves the problem. However, when I plugged it back in this time, nothing happened. I tried all the little quickfix/reset tips I could find online but nothing worked. Do I need to send you my main board or my power supply board? I’m thinking main board, right? Please let me know. Thanks for your guidance!
So my Sony seems to get stuck in a loop, after many tweaks. Did a restore of my TV, then got rid of a lot of "bloat-ware", then moved a few apps to a usb drive. Then I rebooted and I wasn't sure why it was caught in a loop, then thought to remove the usb drive, then power back on then insert the usb and all was good. Any suggestions and/or heard of this? My apps are working on the usb. My main app on there is an iptv app. Is there a way to change the boot order? Maybe it checks the USB first and gets stuck? Any suggestions greatly appreciated! TIA!
Is there a way to change the boot order? If there is, I do not know how but it is also strange that it is getting caught up and has issues with the flash-drive plugged in, that should not be the case. A work around would be to keep your TV "offline" as in disconnected from the internet and using an amazon fire stick or a Roku device through one of your HDMI to access your smart apps moving forward. This should not affect the boot up and would allow you to always have your apps available. I don't have any boot up issues with my personal Sony TV at home, but I still use a firestick as I find it is much easier to use the firestick to navigate the smart options and since it is an android based device I can use the firestick remote to control the basic functions of TV.
hey nick quick update on my sony xbr 55x 900f i did the forcw reset like you mentioned and now im getting sound. during the process i saw a white line going across the top im going to try it one more time. i might be interested in the board repair if i cant get the picture to come back
If you can't get the picture to come back, the last thing you could try is to force an update as well but I don't know that it will help. What you would need to do is go to the link below and download the file: www.sony.com/electronics/support/lcd-tvs-android-xf90xx_x90xxf-series/xbr-55x900f/software/00262031 Once downloaded extract it to an empty flash drive. Then rename the file to upgrade_loader.pkg Then with the TV disconnected from power, plug in the flash drive and then plug-in power. Don't disconnect it from power, the update should take automatically and will be indicated with the white light at the bottom pulsing on and off. The update can take a full hour so be patient. For more details and troubleshooting on that, you can check out the other video below: ua-cam.com/video/3kYPjIHt8Lc/v-deo.html If you still can't get it though, then unfortunately yeah your next step would be to send it in for a repair at that point. www.nickstvs.com/store/p2839/XBR-55X900F.html
Hi Nick my Sony Tv XBR-85X850G has the boot loop issue, I didn’t see it on your list of boards you repair on your website, is it a board issue and do you think you can repair it? Thanks
Hello James, I recieved your email to our support@nickstvs.com email and I have linked you to the repair service for that circuit board. We should have no problems repairing it. This is our bread and butter!
I have the XBR-55X900C and the continual loop has been going on for months up to maybe a year now, and we've been without a tv since.

Okay this is what worked for me, I tried holding down the power button and the down channel key on the tv And then plugging in my device, Several times It didn't work. So what I did was Hold the power button And the volume key And then plug my TV set in And it gave me is like a Halo circle With different colors.Then I unplugged my TV. I held the volume button And the power button then Turned my TV on and Waited till I saw the tv Cut on And cut off. The TV cycled a few times and it was fixed. You're going to have to try using the volume up or down key to see which one works,But holding the up-and-down channel key did nothing for my TV.I Hope that helps someone
hey nick this video is sort of similar to what i have going on. i have a Sony xbr 55x 900f thats similar to this set. it powers on and i get a blank picture it seems like a boot loop but i dont see the logo. is it a firmware issue? and can i do a factory reset?
Hey Jeremy, Yeah the 900F series also suffers from the same issues as the one in the video. What I recommend you try is force reset your TV by unplugging it from the wall. Then using the buttons on the back of the TV press and hold the power and volume down. Keep them pressed in as you plug the TV to power and keep those pressed for at least 15 seconds or until the green light comes on. Then you can release and this should force a full reset on the TV. If this does not work then your mainboard is probably defective in a way that a reset won't fix. You can either buy a new mainboard at that point, or if you can't find a good deal, we do offer a service to fix them which is linked below: www.nickstvs.com/store/p2839/XBR-55X900F.html Also if you have more questions, don't reply to this message, instead just post a brand new comment, or else I won't be notified of the reply.

Hi,i have a sony xbr55x900h purchased in 10/20 ,its displaying a vertical white stripe with a few thin lines in stripe in the middle of the tv...ive since replace the TCON board & it still displays the white vertical stripe...any help in fixng this issue?
I am not sure if you can fix that. It sounds like it could be a panel failure. I would need to see pictures of the lines in question. Please take pictures and send them over to our support@nickstvs.com email and we can take a look and let you know.
Be careful taking off the back cover, I accidently pulled the electrical wire off the circuit board. Had to have a friend solder it back. Other than that this fix worked great. TY!
Hello Nick, I have a Sony XBR75X850D with sound but no picture. The white Sony light illuminates and the main board has been serviced. Can you please advise me
Hello Greg, Can you confirm you have paired the mainboard to the TV set? How much time did the update take? Did you have to go through the process twice? Was this module serviced with us? Often this can be due to the LVDS ribbons not being properly connected. I personally pair these myself to our test sets when customers send in their boards for repair. Trust me I have done this hundreds of times and I still have to reseat ribbons sometimes and experience the same thing you are right now. If this still doesn't work, alternatively if you were to disconnect both ribbons from the mainboard and boot up the set, if the T-con and panel are working, you would see the color pattern test. This would confirm the rest of the set is okay and the mainboard is the issue. Now Mainboard being the issue doesn't necessarily mean the mainboard is defective, it could simply mean it didn't pair properly and may need the process to be done again. If you have any follow-up questions, I suggest you contact us via support@nickstvs.com directly, if you respond via youtube, we won't see the comment unless you post a new comment instead of a reply. For some reason, we don't get any notifications when a reply is posted, only for new comments. Hope this helped
@@NicksTVRepair hey Nick, Thanks for your quick response. Last year I purchased a control board from Ben Owen at PartServ in Atlanta. He has closed due to Covid. Ben sent me a compatible main board which I installed and a picture appeared within 30 seconds but only lasted about two minutes. I sent my original main boato main boards
@@NicksTVRepairPartServ tested my original main board and it was functional. The Sony was kept unplugged and in storage for six months . Yesterday I plugged in the XBR75X850D and held the manual switch in the back and held it for ten seconds. The white light under SONY illuminated brightly and I am able to operate power on with remote control. The unit was never serviced with your business. I will try to update tomorrow and advise. Any suggestions?
This is most likely a fault with the LEDS but there is a small chance it's power supply or LED driver. In my experience it's almost always LED strip related.
Nick, I have a 55X900C. I performed a factory reset from the options menu. It went off after confirming I wanted to erase all my information and apps. I waited 24 hours as I know my tv is older and takes time. When I try to turn it on, it does nothing. So I followed the instructions from Sony and unplugged for 2 minutes and then plugged it back in. I get the Sony logo and briefly and then the screen goes blank. It does not turn on using either the remote or the power button on the back. No other devices are plugged into the tv. I assume it's a main board failure but wanted to ask your opinion first.
Yes that is going to be a mainboard failure. If the mainboard is unable to properly update or crashes due to an update, it means that the board has a defect and needs to be repaired. If you aren't able to find an affordable replacement, we do offer a repair service of your original board which I have linked below www.nickstvs.com/store/p2271/XBR-55X900C.html
Hello Nick, I have got a Sony 65" XBR 850e that has horizontal Pink/purple-ish bars going across the screen with a snowy background. At times I see a hint of green on the snowy portion that would typically be mostly whitish. the bars are about an inch half wide and staggered once they meet in the middle of the screen by about half of one bar to where it is not a complete solid bar going across. Any idea? Thanks for your time
Yeah that's a common issue we see with main boards for that model. Here, take a look at the listing I am linking below, and check out the second picture of the listing. www.nickstvs.com/store/p2347/XBR-65X850E.html Is that what you are seeing? We have had at least 40-60 or so main boards come in for repair with this failure . It's not the most common main board failure we see for this model but I have only ever seen main boards cause this issue, so with 99.9% confidence, this is a main board issue you are experiencing.
Hey, Nick, don't know if anyone has asked you about this, my TV is XBR-55x850C, it has a bootloop issue as you described, I also tried using Forced Factory Reset and USB flash drive to update the software, but TV won't recognize the USB at start nor successfully boot into the factory reset. I spent hours with Sony tech support, but they concluded it's a motherboard failure. Should I just go ahead replacing the board or is there anything I could do to fix the board or troubleshoot anything further to isolate the root cause? Thanks for your feedback!
Hello, In terms of further troubleshooting, that is not necessary, you most definitely have a mainboard failure. In terms of repairs, as long as you renamed the file on the flash drive, and it is still not pairing/updating, then you have essentially done everything you can on your end to fix the module. Anything else will require much more in-depth solder working and chip replacements. At this point, a replacement or repair of your original board through our mail-in repair service are your only 2 options. If you aren't able to find a good functional board at a decent price, you can always send us yours for repair. I have copied a link to our repair service listing below: www.nickstvs.com/store/p2277/XBR-55X850C.html Send us an email to our support@nickstvs.com if you have any questions.
I had a similar problem like you. Make sure your USB stick is formatted as FAT 32. Some TVs cannot read certain USB sticks, try to copy the firmware update (1,5GB) onto a different stick formatted in FAT32. Insert the stick to the TV and hold the Power and Volume down button simutaneously. You should get a green light after 10 to 20 seconds, when you get a green light release the buttons and wait a bit. Firmware should install all by itself, do not disconnect the power cable. Good luck
@@TheravadaMusic that's exactly what I did but the TV failed to recognize the USB. This is a known Sony firmware upgrade issue that causes motherboard damage and Sony knows about it and that's why they extended the 1yr warranty to March 31st, 2021 for the model ending with "C". Unfortunately, my issue happend in April, and they won't grant the warranty claim. I had an argument with them over the phone, and they won't bend the rule. My TV is under 5yrs old. Sony doesn't stand behind their product. Software causes the hardware issue, they should not put a warranty time limit for "C" models.
@@dingxu321 Have you tried the update with different usb sticks ? The first stick I used was from sandisk I bought in 2019, the TV could not read it. Then I used an old stick from 2015 and it worked. I had the exact same problem like you and could fix it with an "older" USB stick. My TV is a Sony Bravia KD-43X8305C. Fingers crossed.
Hey Nick I have the xbr-65x930c TV and it's power cycling right at the beginning when u turn it on.... as stated in your in video and comments it's the main board...do you offer or know anyone that will repair the original board or is it not repairable? Plz lmk if you can..

Thanks for the videos. I have a xbr-55x900c which turns and has the do not unplug logo flashing. The white light will flash then stay steady. Any solutions? Thanks in advance for any help
That can take over an hour before it finishes. If you unplugged the TV from power while that was on the most likely the mainboard is bad. Otherwise, you may have to manually update and or pair your TV. I have a video linked below that shows how to properly pair/ update your. ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
It depends on the board and what repairs need to be done. Some models are different for the North America market than other areas of the world and thus have different types of boards that are not compatible. What issues are you experiencing and for what models? Please respond via email support@nickstvs.com or I may not see your message. If we are unable to assist you, we have a contact in France that does a lot of similar repairs as we do that i can recommend.
Hello, Unfortunately I won't be able to help, based on what you are describing you most likely have bad LED's and will have to either have your LED strips serviced or purchase new ones. We do not have them for sale currently nor have a service available at this time.
Nick I have a Sony XBR-55X900F. When I plug it in and it starts up it goes into like a test pattern like sequence. Dark contrast to a light contrast to a RED screen,Blue screen,Green screen and a Checker board screen. I have sound from the factory reset. but screen goes to a test pattern like loop.
Hey John, Generally the test pattern is triggered by disconnecting the ribbons from the main board to the T-con board. Once this happens the T-con automatically displays that pattern which is used to confirm the TV screen is in good working condition as well as the T-con board. Generally when this is triggered inadvertently it is after a main board replacement and is an indication that the ribbons were not properly installed or are just not seated exactly as they should and thus not communicating with the T-con. However based on the information you provided it does not sound like the main board was replaced, but that this issue occurred on it's own from one day to the next. I don't know if there is a chance this could work, but have you tried the pairing/update of the board with a flash-drive? If not, please check our video linked below on steps for this. ua-cam.com/video/3kYPjIHt8Lc/v-deo.html If you still have issues, either message us through this video or the one linked above.
Hey I don’t see the link for the 4 blink error code. My XBR65X900C turns on and then off after a while. I grounded the BL-ERR wire and that got the TV working again however after 2 days the TV now has a black wave across the screen, blacklight going on and off. What board or what is the issue I would like a permanent fix. Thank you in advance.
4 blinks is generally the LED driver. Grounding the BL_error wire can solve the issue. When you state you have black wave across the screen, what do you mean exactly? It is possible your backlight has such a sever failure that grounding out the error pin may not be enough and a full replacement or repair of your LED strips may be necessary.
Hi Nick. I have a XBR-75X900F that turned on for a few minutes then turned off. The android logo came on and off twice and then was completely dead. Sony customer support suggested that the power board needed to be replaced. Do you ever see this issue as a power board issue and not a main board issue? Thanks.
Jeffrey, I have never seen a power supply do that. Unfortunately their service manuals and troubleshooting systems aren't 100% I would be more inclined to believe you have a failed Main board than a failed power supply. Unfortunately we don't service those, which means we don't have a tone of experience with those models yet, so make sure to take that into consideration when taking my advice. Without having a chance to troubleshoot the tv myself, I would put my money on the main board. If you have any additional questions or information regarding symptoms, let me know.
Thanks Nick for the quick reply! I was afraid you were going to say that. Do you know anyone in the Denver area that can work on this set? Sony won’t stand behind this $3600 TV that is only two years old. They just told me sorry for your inconvenience.
Nick you were correct that it was the main board that had failed. After I replaced both power boards and still had a dead set, I replaced the main board. I then watched your video on pairing the board and uploading the firmware. It worked like a charm. Thanks for your very thorough and informative videos!
Hi Nick I have an XBR75X940C and it shut down and won’t turn backon it immediately shuts off and flashesI 4 blinking red light indicator, I grounded the BL_ERR wire from the APS388 board connector and have performed the power button-volume down at same time and and it now tries to power up and the LED turns green but then shuts old and same 4 light code, I also performed power button on TV/up arrow button on remote and this gets me to hearing the start up music briefly then back to 4 light code. Any advice as what to do next would be appreciated or which boards I need to send to you for repair?
Hello Troy Check in DC volts R9027 on the B* Board. If you get 0.897 DC Volts or less, then replace the B board. If you get Between 0.898V to 2.997V then Change LD board or G* board.

I have a XBR65X900C that had a red led code that would not allow the tv to turn on. Found a fix that moved a ground wire on the mainboard to a different position which fixed that issue but, now the LED's at the bottom of the screen turn off and on at different positions and flash. How can this be resolved so that I can have this tv working again? If needed I can provide video proof for reference.
You will need to do a full replacement of the LED strips and or have them repaired by a technician. This is a very advanced repair and I do not recommend you do it yourself as it has a high risk of damaging the set further if done incorrectly.
Hello! I have a Sony Xbr55A8f and every time I try to turn it on or factory reset it, it makes a clicking noise and either freezes when the android logo is just dots, or partially goes through the animation snd resets itself. Any idea what this may be?

Hello Elsy, What you are describing is one of the most common failures we see with these TVS. The failure is due to to main board malfunctioning. The main board has failed in a way that it can not be fixed with a reset or software update. It must have hardware replaced. You can either replace the main board with a used one if one becomes available, or send in your main board to our repair facility. We have fixed this issue many times in the past and can do so for your board. For more info please see the link below: www.nickstvs.com/store/p2345/XBR-65X900E.html If you have any follow up questions, please do not hesitate to contact us back.
Hi Nick, I have sony bravia 55X9000E model which shows red, blue, green white color screen on startup in loop with music. I have tried resetting with TV buttons but did not work. Please help, how to fix it?
Hello, The issue you are experiencing is due to improper contact between the LVDS ribbons and the connectors either on the mainboard side or the T-con side. Try disconnecting them, cleaning them out and reconnecting. You may need to pair the mainboard after doing this For more details on pairing, check out this video: ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
It sounds like you have a mainboard failure and will need to either have it serviced or replaced. In order to force a reset, you can unplug it from power, and hold down both the volume down and power button at the same time. NOT on the remote, on the buttons on the TV itself. Plugin the TV while holding both those buttons down and keep them pressed in until the green light comes on. If you don't see the greenlight within 20 seconds of pressing down those buttons, try again. If it still doesn't work then it's because your mainboard is broken beyond being able to be reset or updated and will need hardware to be replaced. If you have any other questions, don't hit the reply button but instead write a new comment. I only get notifications on new comments, not on replies.
Hi nick, I do have a Sony XBR-65X750D which keep rebooting even if I try the factory restore, its stocked on boot loop, I couldn't do anything and sony didn't help at all, could you tell me whats the issue and which part need replacement please, your help will be appreciated.
Hello, The failure you are experiencing is a main board failure. This is a common failure for these models. There should be some modules available for sale on eBay. The part number for the main board is: A-2094-466-A Pro tip, this main board is cross compatible between the following models XBR-65X750D XBR-55X700D XBR-49X800D XBR-49X700D XBR-43X800D So if you find a main board that was removed from any of those models, it will work with your TV set. This means if you do a search for the XBR-65X750D and the cheapest main board is $150, then try searching using the XBR-43X800D and you might find someone selling the same board for $85.

Hello Oreo Cookie, The video is listed to be for the 900C and 910C diagnostic, however it can also be used to identify the faults with many other sony boards within the 2015 C models as well as the 2016 D models such as your set 850D. An 8 blink error code, just like the video suggest is a software failure. We suggest downloading the newest software available on the sony website and force updating your TV set. You can do this by following the steps in our pairing procedure video which I have linked below: ua-cam.com/video/3kYPjIHt8Lc/v-deo.html I have set the link to start the video at about 3 minutes since that will be when the software download instructions start. If downloading the software doesn't work, then try changing the software file name to upgrade_loader.pkg ua-cam.com/video/3kYPjIHt8Lc/v-deo.html This second link is to the same video, simply a little further into the renaming of the file section of the video. If this still does not resolve the issue, then this would mean the software failure has affected the main board in a critical way which can not be recovered with an update. At this point we would suggest sending the board to our repair service center to be serviced. I have linked the repair service listing below: www.nickstvs.com/store/p2513/A2129709A.html Please do not hesitate to contact us bakc with any questions you may have. Sincerely, your glass of milk.
Hi, Nick. I have a 55x900f that has started to go into a boop loop error. Sometimes it will make it past the initial setup where i can choose the language and network, but almost each time i push a command on the remote the tv cycles off and back on again. And then on the race occasion i do make it past the setup the TV just turns on and off repeatedly. However, I am not showing any red blinking error codes on the front of the TV. Can you advise?
Jesse, This is going to be another main board related failure. A lot of these 4k sets from Sony seem to all be plagued with similar type failures. Sometimes it is a software failure, sometimes it is a processor failure. I would suggest purchasing a replacement main board, it will resolve your issue. The board number for your module is: 1-983-249-21 The part number for your module is: A-2197-252-A
@@NicksTVRepair Nick, thanks so much for the quick reply. I have ordered a new main board and hope to have it in and installed this weekend. I appreciate your help!
Okay this is what worked for me, I tried holding down the power button and the down channel key on the tv And then plugging in my device, Several times It didn't work. So what I did was Hold the power button And the volume key And then plug my TV set in And it gave me is like a Halo circle With different colors.Then I unplugged my TV. I held the volume button And the power button then Turned my TV on and Waited till I saw the tv Cut on And cut off. The TV cycled a few times and it was fixed. You're going to have to try using the volume up or down key to see which one works,But holding the up-and-down channel key did nothing for my TV.I Hope that helps someone
@@NicksTVRepair Nick, thought I would post a reply and say that replacing the main board and following your instructions worked perfectly. However at one point the TV went into a boot loop again and I decided to completely disconnect the tv from the internet. Ever since then it’s worked flawlessly with zero issues.
I have an older xbr55x900A that I have recently changed the main board on. The red LED error code has gone away but I now have a problem that when I power it ON, the backlight comes on for about 2sec, then I hear a relay click, and the backlight goes out. The power remains on, but there is no picture at all. Any Ideas? What lead to the main board change in the first place was most likely a power arc from an HDMI port over driving that port (I think) - because it failed just after I inserted an HDMI device. Any ideas if I also need to change out the power boards, or does this sound like a ribbon cable problem? Thanks all!
Check the connector on the power supply board that links the power supply to the main board. One of the pins should be a BL-ERROR pin. Check to see if there is any voltage on it. If your TV is detecting a backlight error, you will see some voltage. If there are no Back-light errors then that wire will read 0 volts and indicate the issue is coming from somewhere else. I guess something that would be also very important would be for us to know what the original error code was. That may help us understand what is going on now.
What about an XBR-X850D that works fine, then at random will shut off and restart. Sometime it will work for 5 minutes, sometimes for hours before "restarting".... Any thoughts?
Dwight, I highly recommend a Factory reset first. If the issue persists, then a software update. If the issue still persists, you will need to have the main board either replaced or serviced.
Hi Nick, I have a KD-65X9000B it gives the Sony logo, shows the TV for a second and then goes blank with 8 Red Blinks. Please help suggest a fix. Thanks.
8 blinks is a software failure. Your mainboard needs to be replaced or fixed. You can try a force update by pairing the mainboard again. Check out the video on how to do that ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
We are still having issues with the 7 blink codes. So far we have been able to fix a little under half of the boards with that failure and have done the following to successfully fix a 7 blink. Failed HDMI IC needs to be replaced Failed CPU needs to be replaced CPU needs new thermal past. Temp sensor malfunction. The problem is that we haven't found any reliable ways to diagnose and identify these issues yet.
Hi Nick, I have the Sony XBR-65x900c 3D - It just started displaying vertical lines (from bottom-up) and also is "ghosting" - Factory reset did nothing - it is on the most current software - I took off the back panel and disconnected and reconnected all the cables and ribbon cables. Nothing clears the issue. Any ideas or suggestions?
Gary, You wouldn't happen to have a video you could take or that's already posted online you could link me to so I can get a visual of exactly what you are experiencing would you?
I have an XBR-55X907E. The TV started to show 4 red blinking lights and turns off. I reset the TV to factory defaults and didn't set up any network functionality. It seems to have resolved the issue. However, I will have to buy a chromecast to recover the smart functionality.
I would recommend you purchase an amazon fire stick as it is about the same price, but is also an android based device just like the Sony tv's are. What this means is that you can control your Fire stick device using the Sony remote. Additionally I do personally believe the operating system for the Amazon fire stick is a bit better and easier to navigate than most other similar devices.
Hello, It's very likely that this is a main board failure. It's a common symptom we see with this model in particular. Here is more information regarding this model: www.nickstvs.com/store/p2789/XBR-55X700D.html Please let us know if you have any questions!
My TV was stuck on the reboot loop, I fixed it by - 1. Unplug the TV from the mains. 2. Press and hold Power button and (-) Volume button 3. Keep pressing the buttons while plugging the TV back to the mains 4. Keep pressing for 20 seconds or more till the small red LED turns into green. 5. Wait for few minutes till the TV resets itself
John, Nice work, it's always nice to be able to resolve an issue that easily. Pressing and holding for 20 seconds the volume down and power button while plugging in the TV will force a reset. In some instances such as yours it will fix simple software issues. When it comes to hardware issues however this won't work unfortunately. I hope the fix lasts. If not it's probably a sign of a more serious underlying issue with the mainboard.
Have a thorn 65inch tv when i select input on remote control and select smart tv the Android logo loops. Cant find a reset button. Any help be appreciated thank you
If you go under the system settings, there is an option to reset the tv to factory default. I would highly suggest doing that first. If that does not resolve the issue, I would then suggest performing a software update. If that still does not resolve the issue, then you will need to either send in your board for repair or find a replacement. Please let us know if you have any questions.
my sony xor-55x900e didnt turn on , then it did turn on but only showed sony and they the animated circles and turned off , then it turned on and got all the way to the channel menu and stayed on for a minute and then turned of again. can you help me?
Hello, Kairus1, What you are describing is very common and just like the 900C the 900E TV has that exact same symptom which is a main board failure. This is something you would need to send in for repairs. Check out our mail in repair and return service linked below for more details: www.nickstvs.com/store/p2344/XBR-55X900E.html
for me, my sony xbr65x900c is working just fine... besides the screen flashing black. not even the entire screen though, certain points of the screen go black at completely random times, then come back. I have no clue what to do.
It sounds like you have LED strip failures. The symptoms you are describing for the LED failure however is not good news in the sense that there is no easy fix. The only way to properly repair the set would be to get the LED strips replaced or serviced and that is a very labor intensive and delicate operation for these sets. I would suggest contacting your local TV shop and seeing if they have experienced replacing these strips in the past and what kind of charges they would have for this type of repair.
Phil, I am not familiar with this model specifically but I would suggest a factory reset and software update if an update is available. If that does not resolve your issue, then you may need to replace the mainboard.
@@NicksTVRepair Already solve the issue I'll buy LG instead this one that I've bought I sent to diagnose but it will not solve the issue. Repair mens look uncertain about it.
I highly suggest resetting the TV to factory default and performing a software update asap if one is available. If the issue persists, you may have to replace the mainboard.
My tv goes through the on screen process like it is resetting, but after it finishes with the circle image and shows the Sony logo, the screen goes black and it plays a soft piano-type music.
It sounds like you did a force reset to your board. Have you tried updating/pairing it? If not, check out the video linked below and give it a try: ua-cam.com/video/3kYPjIHt8Lc/v-deo.html If that does not resolve the issue then you may need to have it fixed or replaced.
Okay, the screen won't come on. Does the backlight come on at all? meaning do you get a glow from the screen? Do you get any audio from the TV set? If the answer is NO to the above the first step I would suggest would be to try a factory reset. You can follow the Factory reset instructions from Sony's website linked below: www.sony.com/electronics/support/articles/00159487 If that doesn't resolve it, then I suggest checking out our software update video which will demonstrate how to update the TV using a flash drive if the set doesn't turn on. The video linked below starts at 3:07 which is where we show how to download the software from the Sony website ua-cam.com/video/3kYPjIHt8Lc/v-deo.html If that still doesn't work, then we suggest force updating the TV by changing the file name. Further instructions for this will be at the 5:20 times stamp which is linked below: ua-cam.com/video/3kYPjIHt8Lc/v-deo.html Please let us know if either of these works for you, and if so which one resolved the issue. If neither options resolve it, then please let us know as well. In that case, your mainboard has a failure that is severe enough that it will need to have components replaced and will have to be sent in for repair. If you have any questions, just post a reply!
Based on the information we are aware of regarding the 5 blink code the issue could be either the panel, aka the screen, the T-con board, or the BMX board which is your main board. Since you have already replaced the T-con board we would suggest you try replacing the main board next as the Panel is going to be much to expensive to be worth replacing. Unfortunately there is not more information or any further troubleshooting that we are aware of for this model as it is not a model that we commonly work with.
@@NicksTVRepair Thanks for the fast reply. I observed that, after replacement of T con, firmware need to be updated. At that moment tv is working fine for some long time. After turning on tv around 6 to 7 Hr when switchoff, it's not getting on. I thought u get my point what I mean.
We have been seeing more and more issues lately with the 900F mainboards. We have been fixing a few and what you have sounds like a common EMMC failure that we can fix. If you want to give it a try with a used module online, go for it, there are still some cheap ones available out there, however, we have been hearing from customers that they tried purchasing boards first without success, I don't know why but there seems to be a lot of bad mainboards out there, so if replacing the mainboard doesn't work, just let us know and we can always just fix your original. www.nickstvs.com/store/p2840/XBR-65X900F.html
I have the KD55X8005C and it's stuck on the Google circles. Has been for hours. I tried a hard reset with the power and volume down buttons, I get the green led, release the buttons and nothing happens. Press the power button again and the circles are back. No welcome screen, no Sony logo, just the circles. Any ideas folks?
Kather, when you say the screen is oscillating, do you mean the screen is shaking/jittering? Do you ever get a blinking code or just the blank screen and nothing after that? Because you do get the logo to appear on screen I think it is safe to rule out the screen and T-con board as being at fault. Most likely your main board is the cause of the issue, however since we do not actively service/fix that type of model I can't say I am extremely familiar with it. Based on my experience with other Sony models however I would put my money on replacing the main board. If you have follow up questions, we may be better able to assist you if you contact us directly on our support email. It seems we don't always get reply notifications on UA-cam.
Jessica, It seems you have a mainboard failure but there are a few tests you can do. I recommend turning the lights off and powering on the set. After the Sony logo and the Android logo go away and the black screen is all there is, does the screen glow at all or is it pitch black? Are you able to turn the TV back off or do you have to unplug it? Here are a few things you can try to fix it. Unplug the TV from power, press and hold the volume down and power button on the buttons on the TV, not from the remote, and while still holding those buttons plug the TV back in. Keep pressing those buttons until the TV turns on or the pilot light (standbylight) turns on green. This will force a reset on your TV. If you can not get the reset to work, you can also try pairing your TV set. Go to the sony support website and download the software for your TV set. You can watch more details on how to do that here ua-cam.com/video/3kYPjIHt8Lc/v-deo.html I have time-stamped it where you want to start watching. Good luck
Hi i have a sony xbr55x900f Everything work for 45 minutes Then it froze whit sound or back screen And Android restart And it work again for 30 Them froze or black screen again And Android restart again
Raul, I highly recommend you perform a factory reset and software update. This is not always going to work depending on the level of your failure on the board but it is the only solution available aside from either replacing the mainboard, or sending it in for repair.

This link below has a lot of information regarding force resets and factory resets. Every year and model is different, so make sure to read through the information first to identify which button combination is the correct reset combo for your TV www.sony.com/electronics/support/articles/00159487
That's a very common mainboard failure. If you want to send in your mainboard for repair, we do service it and offer a 1 year warranty on the repair! Check the description for links and additional info!
According to my information, 3 blinks can be the following: Main 5.0V failure [DC_ALERT] Audio amp. protection [AUD_ERR] Tuner or demodulator I2C No ACK [TU_DEMOD] [Note.1] HDMI Switch/Equalizer I2C communication error [HDMI_EQ] : Main board, : Speaker So most likely the mainboard, with a chance the speakers are at fault. A simple test is to disconnect the speakers from the mainboard and power it up. No more 3 blinks with speakers disconnected then your speakers are the fault. Still get the 3 blinks with the speakers disconnected, then your mainboard is the fault.
You may have a mainboard failure then. I recommend replacing it. If you can not find a fair price, you can always send it to us for repairs. Check out the description for links to our services and pricing.
XBR-55X990E has wide color bars red Green blue which alternate direction vertically and horizontally then turns red and shuts off. I am guessing this is a main board problem, Have you experienced this ? Can you give me the correct board number ? Any suggestions ?

Hello, That is a common failure we see for the 850E and 900E sony boards. In this video, we didn't cover that failure as we only talk about the 900C and 910C models which don't experience that issue. That is a mainboard failure you are experiencing. If you can find a replacement mainboard, I would suggest you purchase it. If you are unable to find a replacement, we do offer a mail-in service for that problem exactly with a 1-year warranty on the repair. www.nickstvs.com/store/p2344/XBR-55X900E.html If you have any follow-up questions, our email is support@nickstvs.com

Nick has been very helpful in helping me diagnose a problem with a XBR-65X750. We are still trying to pin down the issue but I have no hesitation to recommend Nick. 5 star service...
Thanks Willy!
Ok. It’s six months ago since you posted. Has he managed to diagnose?
Nick is spot on in his instructions and the repairs are a good value and quick.
Happy to hear you enjoyed the video!
Hi Nick I have a XBR 65Z9D with a 8-blink power on problem then nothing, it will not display anything. I have replaced the main and power board, the original problem was half white screen and half black. I know my connections and replacements of the items were also done correctly as I have worked on thousands of professional items. Where do I go from here, thanks Brian.
If the replacement mainboard is giving you 8 blinks, then you most likely received a none working mainboard. 8 blinks is indicative of a failed mainboard.
Return it and get a new one.
Hi Nik. I have a Sony XBR-65A8G . Is turning on sound is good but no pic? Can you pleas help me about that ? Thank you
Turn the lights off in the room, and make it as dark as possible. Now turn on your TV. Do you get a glow from the screen? If yes then that means your LEDs are good and turning on. However, it also means you may have a bad screen. If no glow then your LEDs are not turning on although that doesn't mean they are bad, perhaps they aren't getting power or the turn-on command. If this is the case you may have a bad mainboard. Something you can do in that case is shining a flashlight onto the screen, do you see the image very faintly? If yes then that would mean your LEDS are most likely bad which for this set they are imbedded in the screen so it means buying a new TV. If not then I would suggest a new mainboard.
Please keep in mind this is not a proper diagnostic, this is based on my own opinion what I think are the most likely reasons for the set to have gone bad and are purely speculation. If you would like for us to help you further with diagnostics, we do have a testing and diagnostic service where you can mail in some of your circuit boards which we can live test in our system in our shop at a $20 bench fee per board. Our contact info is in the video description if you have more questions.
Do you have information or a video for 3 red blink code for the Sony XBR-65X900C? This model has a Power Supply Board APDP-330A1 & Sub Power Supply Board APDP-180A1
Hello Jason.
One of the reasons we haven't covered the 3 red blinks is because of how rare it is.
According to the service manual, a 3 blink code is due to a faulty mainboard. While it is not common, I do believe we have actually serviced that fault by replacing the HDMI processor IC. It's the large IC chip next to the HDMI ports with 200 pins or so.
If you want to send it in for repair, we can replace that chip.
Hi Nick. The picture on my XBR-55X900F froze in the middle of a film (on Prime, not DVD) and when the unit would not respond to any command from the remote, I unplugged it (something I have found myself having to do with increased frequency in recent months). Usually this solves the problem. However, when I plugged it back in this time, nothing happened. I tried all the little quickfix/reset tips I could find online but nothing worked. Do I need to send you my main board or my power supply board? I’m thinking main board, right? Please let me know. Thanks for your guidance!
Yes that sounds like a mainboard issue. Fortunately you can send it to us and we can take care of it for you.
Thank you for reaching out to us!
Nick you saved my life by helping me with my Sony xbr-55x850d. I thought I was going to have to buy my wife a new bedroom TV. 😂
Glad to hear you got it back up and running!
So my Sony seems to get stuck in a loop, after many tweaks. Did a restore of my TV, then got rid of a lot of "bloat-ware", then moved a few apps to a usb drive. Then I rebooted and I wasn't sure why it was caught in a loop, then thought to remove the usb drive, then power back on then insert the usb and all was good. Any suggestions and/or heard of this? My apps are working on the usb. My main app on there is an iptv app. Is there a way to change the boot order? Maybe it checks the USB first and gets stuck? Any suggestions greatly appreciated! TIA!
Is there a way to change the boot order?
If there is, I do not know how but it is also strange that it is getting caught up and has issues with the flash-drive plugged in, that should not be the case.
A work around would be to keep your TV "offline" as in disconnected from the internet and using an amazon fire stick or a Roku device through one of your HDMI to access your smart apps moving forward. This should not affect the boot up and would allow you to always have your apps available. I don't have any boot up issues with my personal Sony TV at home, but I still use a firestick as I find it is much easier to use the firestick to navigate the smart options and since it is an android based device I can use the firestick remote to control the basic functions of TV.
hey nick quick update on my sony xbr 55x 900f i did the forcw reset like you mentioned and now im getting sound. during the process i saw a white line going across the top im going to try it one more time. i might be interested in the board repair if i cant get the picture to come back
If you can't get the picture to come back, the last thing you could try is to force an update as well but I don't know that it will help.
What you would need to do is go to the link below and download the file:
www.sony.com/electronics/support/lcd-tvs-android-xf90xx_x90xxf-series/xbr-55x900f/software/00262031
Once downloaded extract it to an empty flash drive. Then rename the file to upgrade_loader.pkg
Then with the TV disconnected from power, plug in the flash drive and then plug-in power.
Don't disconnect it from power, the update should take automatically and will be indicated with the white light at the bottom pulsing on and off. The update can take a full hour so be patient.
For more details and troubleshooting on that, you can check out the other video below:
ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
If you still can't get it though, then unfortunately yeah your next step would be to send it in for a repair at that point.

hey nick this video is sort of similar to what i have going on. i have a Sony xbr 55x 900f thats similar to this set. it powers on and i get a blank picture it seems like a boot loop but i dont see the logo. is it a firmware issue? and can i do a factory reset?
Hey Jeremy,
Yeah the 900F series also suffers from the same issues as the one in the video. What I recommend you try is force reset your TV by unplugging it from the wall.
Then using the buttons on the back of the TV press and hold the power and volume down. Keep them pressed in as you plug the TV to power and keep those pressed for at least 15 seconds or until the green light comes on. Then you can release and this should force a full reset on the TV.
If this does not work then your mainboard is probably defective in a way that a reset won't fix.
You can either buy a new mainboard at that point, or if you can't find a good deal, we do offer a service to fix them which is linked below:

Hi Nick. No vidéo on Sony KD55A1? My tv is dead to
You most likely have a bad mainboard but I don't know where you can find one for that model specifically.
Hi,i have a sony xbr55x900h purchased in 10/20 ,its displaying a vertical white stripe with a few thin lines in stripe in the middle of the tv...ive since replace the TCON board & it still displays the white vertical stripe...any help in fixng this issue?
I am not sure if you can fix that. It sounds like it could be a panel failure. I would need to see pictures of the lines in question.
Please take pictures and send them over to our support@nickstvs.com email and we can take a look and let you know.
Be careful taking off the back cover, I accidently pulled the electrical wire off the circuit board. Had to have a friend solder it back. Other than that this fix worked great. TY!
Are you referring to the power cable or some of the other smaller wires connecting on the other boards?
Hello Nick,
I have a Sony XBR75X850D with sound but no picture. The white Sony light illuminates and the main board has been serviced. Can you please advise me
Hello Greg,
Can you confirm you have paired the mainboard to the TV set? How much time did the update take? Did you have to go through the process twice?
Was this module serviced with us?
Often this can be due to the LVDS ribbons not being properly connected. I personally pair these myself to our test sets when customers send in their boards for repair. Trust me I have done this hundreds of times and I still have to reseat ribbons sometimes and experience the same thing you are right now.
If this still doesn't work, alternatively if you were to disconnect both ribbons from the mainboard and boot up the set, if the T-con and panel are working, you would see the color pattern test. This would confirm the rest of the set is okay and the mainboard is the issue. Now Mainboard being the issue doesn't necessarily mean the mainboard is defective, it could simply mean it didn't pair properly and may need the process to be done again.
If you have any follow-up questions, I suggest you contact us via support@nickstvs.com directly, if you respond via youtube, we won't see the comment unless you post a new comment instead of a reply. For some reason, we don't get any notifications when a reply is posted, only for new comments.

Thanks for your quick response. Last year I purchased a control board from Ben Owen at PartServ in Atlanta. He has closed due to Covid. Ben sent me a compatible main board which I installed and a picture appeared within 30 seconds but only lasted about two minutes. I sent my original main boato main boards
@@NicksTVRepairPartServ tested my original main board and it was functional. The Sony was kept unplugged and in storage for six months . Yesterday I plugged in the XBR75X850D and held the manual switch in the back and held it for ten seconds. The white light under SONY illuminated brightly and I am able to operate power on with remote control. The unit was never serviced with your business. I will try to update tomorrow and advise. Any suggestions?
Hi nick I have a kd65x9000h Has 4 red blinking code. It gets through android emblem and to language set up then stops ? Any ideas please
This is most likely a fault with the LEDS but there is a small chance it's power supply or LED driver. In my experience it's almost always LED strip related.
Nick, I have a 55X900C. I performed a factory reset from the options menu. It went off after confirming I wanted to erase all my information and apps. I waited 24 hours as I know my tv is older and takes time. When I try to turn it on, it does nothing. So I followed the instructions from Sony and unplugged for 2 minutes and then plugged it back in. I get the Sony logo and briefly and then the screen goes blank. It does not turn on using either the remote or the power button on the back. No other devices are plugged into the tv. I assume it's a main board failure but wanted to ask your opinion first.
Yes that is going to be a mainboard failure.
If the mainboard is unable to properly update or crashes due to an update, it means that the board has a defect and needs to be repaired.
If you aren't able to find an affordable replacement, we do offer a repair service of your original board which I have linked below

Hello Nick, I have got a Sony 65" XBR 850e that has horizontal Pink/purple-ish bars going across the screen with a snowy background. At times I see a hint of green on the snowy portion that would typically be mostly whitish. the bars are about an inch half wide and staggered once they meet in the middle of the screen by about half of one bar to where it is not a complete solid bar going across. Any idea? Thanks for your time
Yeah that's a common issue we see with main boards for that model. Here, take a look at the listing I am linking below, and check out the second picture of the listing.
www.nickstvs.com/store/p2347/XBR-65X850E.html
Is that what you are seeing? We have had at least 40-60 or so main boards come in for repair with this failure . It's not the most common main board failure we see for this model but I have only ever seen main boards cause this issue, so with 99.9% confidence, this is a main board issue you are experiencing.
Hey, Nick, don't know if anyone has asked you about this, my TV is XBR-55x850C, it has a bootloop issue as you described, I also tried using Forced Factory Reset and USB flash drive to update the software, but TV won't recognize the USB at start nor successfully boot into the factory reset. I spent hours with Sony tech support, but they concluded it's a motherboard failure. Should I just go ahead replacing the board or is there anything I could do to fix the board or troubleshoot anything further to isolate the root cause? Thanks for your feedback!
Hello,
In terms of further troubleshooting, that is not necessary, you most definitely have a mainboard failure. In terms of repairs, as long as you renamed the file on the flash drive, and it is still not pairing/updating, then you have essentially done everything you can on your end to fix the module. Anything else will require much more in-depth solder working and chip replacements.
At this point, a replacement or repair of your original board through our mail-in repair service are your only 2 options.
If you aren't able to find a good functional board at a decent price, you can always send us yours for repair.

I had a similar problem like you. Make sure your USB stick is formatted as FAT 32. Some TVs cannot read certain USB sticks, try to copy the firmware update (1,5GB) onto a different stick formatted in FAT32. Insert the stick to the TV and hold the Power and Volume down button simutaneously. You should get a green light after 10 to 20 seconds, when you get a green light release the buttons and wait a bit. Firmware should install all by itself, do not disconnect the power cable. Good luck
@@TheravadaMusic that's exactly what I did but the TV failed to recognize the USB. This is a known Sony firmware upgrade issue that causes motherboard damage and Sony knows about it and that's why they extended the 1yr warranty to March 31st, 2021 for the model ending with "C". Unfortunately, my issue happend in April, and they won't grant the warranty claim. I had an argument with them over the phone, and they won't bend the rule. My TV is under 5yrs old. Sony doesn't stand behind their product. Software causes the hardware issue, they should not put a warranty time limit for "C" models.
@@dingxu321 Have you tried the update with different usb sticks ? The first stick I used was from sandisk I bought in 2019, the TV could not read it. Then I used an old stick from 2015 and it worked. I had the exact same problem like you and could fix it with an "older" USB stick. My TV is a Sony Bravia KD-43X8305C. Fingers crossed.

That can take over an hour before it finishes. If you unplugged the TV from power while that was on the most likely the mainboard is bad.
Otherwise, you may have to manually update and or pair your TV. I have a video linked below that shows how to properly pair/ update your.

Hi Nick, i have xbr65 900C it works but it has dark spot moving on the screen. How to fix it and how much for the part? Thank you
Hello,
Unfortunately I won't be able to help, based on what you are describing you most likely have bad LED's and will have to either have your LED strips serviced or purchase new ones.
We do not have them for sale currently nor have a service available at this time.
Nick I have a Sony XBR-55X900F. When I plug it in and it starts up it goes into like a test pattern like sequence. Dark contrast to a light contrast to a RED screen,Blue screen,Green screen and a Checker board screen. I have sound from the factory reset. but screen goes to a test pattern like loop.
Hey John,
Generally the test pattern is triggered by disconnecting the ribbons from the main board to the T-con board. Once this happens the T-con automatically displays that pattern which is used to confirm the TV screen is in good working condition as well as the T-con board. Generally when this is triggered inadvertently it is after a main board replacement and is an indication that the ribbons were not properly installed or are just not seated exactly as they should and thus not communicating with the T-con. However based on the information you provided it does not sound like the main board was replaced, but that this issue occurred on it's own from one day to the next.
I don't know if there is a chance this could work, but have you tried the pairing/update of the board with a flash-drive? If not, please check our video linked below on steps for this.

Hey I don’t see the link for the 4 blink error code. My XBR65X900C turns on and then off after a while. I grounded the BL-ERR wire and that got the TV working again however after 2 days the TV now has a black wave across the screen, blacklight going on and off. What board or what is the issue I would like a permanent fix. Thank you in advance.
4 blinks is generally the LED driver. Grounding the BL_error wire can solve the issue. When you state you have black wave across the screen, what do you mean exactly? It is possible your backlight has such a sever failure that grounding out the error pin may not be enough and a full replacement or repair of your LED strips may be necessary.
The black wave (flutter)I am referring to is the backlight going out from left to right moving across the screen continuously.
Excellent. Video, thank you!
Glad it was helpful! Thank you!
Hi Nick. I have a XBR-75X900F that turned on for a few minutes then turned off. The android logo came on and off twice and then was completely dead. Sony customer support suggested that the power board needed to be replaced. Do you ever see this issue as a power board issue and not a main board issue? Thanks.
Jeffrey,
I have never seen a power supply do that. Unfortunately their service manuals and troubleshooting systems aren't 100% I would be more inclined to believe you have a failed Main board than a failed power supply. Unfortunately we don't service those, which means we don't have a tone of experience with those models yet, so make sure to take that into consideration when taking my advice.
Without having a chance to troubleshoot the tv myself, I would put my money on the main board.
If you have any additional questions or information regarding symptoms, let me know.
Thanks Nick for the quick reply! I was afraid you were going to say that. Do you know anyone in the Denver area that can work on this set? Sony won’t stand behind this $3600 TV that is only two years old. They just told me sorry for your inconvenience.
Nick you were correct that it was the main board that had failed. After I replaced both power boards and still had a dead set, I replaced the main board. I then watched your video on pairing the board and uploading the firmware. It worked like a charm. Thanks for your very thorough and informative videos!
Hi Nick

Now regarding your issue. No need for videos, I know exactly what is going on. You have a panel failure. I have good news and bad news. The good news is that you can fix it without sending in a board for repair or purchasing a replacement board.
The bad news is that it's going to be too difficult for me to explain in a message or email or even over the phone. I don't have a video yet on how to perform the repair but I will soon.
If you are willing to wait a week or two, I can post a video on how to perform that repair.
Just subscribe to the channel to get the notification when the next video comes out, or if you don't want to sub, just keep checking into the channel every couple of days over the next week or two until you see the new video come out.
I have a XBR65X900C that had a red led code that would not allow the tv to turn on. Found a fix that moved a ground wire on the mainboard to a different position which fixed that issue but, now the LED's at the bottom of the screen turn off and on at different positions and flash. How can this be resolved so that I can have this tv working again? If needed I can provide video proof for reference.
You will need to do a full replacement of the LED strips and or have them repaired by a technician.
This is a very advanced repair and I do not recommend you do it yourself as it has a high risk of damaging the set further if done incorrectly.

Hello Elsy,
What you are describing is one of the most common failures we see with these TVS. The failure is due to to main board malfunctioning. The main board has failed in a way that it can not be fixed with a reset or software update. It must have hardware replaced. You can either replace the main board with a used one if one becomes available, or send in your main board to our repair facility.
We have fixed this issue many times in the past and can do so for your board.

Hi Nick, I have sony bravia 55X9000E model which shows red, blue, green white color screen on startup in loop with music. I have tried resetting with TV buttons but did not work. Please help, how to fix it?
Hello,
The issue you are experiencing is due to improper contact between the LVDS ribbons and the connectors either on the mainboard side or the T-con side. Try disconnecting them, cleaning them out and reconnecting.
You may need to pair the mainboard after doing this

My xbr 55x850d stays in the reboot loop but I can't power it off unless I pull the plug. How can I factory reset it?
It sounds like you have a mainboard failure and will need to either have it serviced or replaced.
In order to force a reset, you can unplug it from power, and hold down both the volume down and power button at the same time. NOT on the remote, on the buttons on the TV itself.
Plugin the TV while holding both those buttons down and keep them pressed in until the green light comes on. If you don't see the greenlight within 20 seconds of pressing down those buttons, try again.
If it still doesn't work then it's because your mainboard is broken beyond being able to be reset or updated and will need hardware to be replaced.
If you have any other questions, don't hit the reply button but instead write a new comment. I only get notifications on new comments, not on replies.
Hi nick, I do have a Sony XBR-65X750D which keep rebooting even if I try the factory restore, its stocked on boot loop, I couldn't do anything and sony didn't help at all, could you tell me whats the issue and which part need replacement please, your help will be appreciated.
Hello,
The failure you are experiencing is a main board failure. This is a common failure for these models. There should be some modules available for sale on eBay.
The part number for the main board is:
A-2094-466-A
Pro tip, this main board is cross compatible between the following models
XBR-65X750D
XBR-55X700D
XBR-49X800D
XBR-49X700D
XBR-43X800D
So if you find a main board that was removed from any of those models, it will work with your TV set.
This means if you do a search for the XBR-65X750D and the cheapest main board is $150, then try searching using the XBR-43X800D and you might find someone selling the same board for $85.

Hello Oreo Cookie,
The video is listed to be for the 900C and 910C diagnostic, however it can also be used to identify the faults with many other sony boards within the 2015 C models as well as the 2016 D models such as your set 850D.
An 8 blink error code, just like the video suggest is a software failure. We suggest downloading the newest software available on the sony website and force updating your TV set. You can do this by following the steps in our pairing procedure video which I have linked below:
ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
I have set the link to start the video at about 3 minutes since that will be when the software download instructions start.
If downloading the software doesn't work, then try changing the software file name to upgrade_loader.pkg
ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
This second link is to the same video, simply a little further into the renaming of the file section of the video.
If this still does not resolve the issue, then this would mean the software failure has affected the main board in a critical way which can not be recovered with an update. At this point we would suggest sending the board to our repair service center to be serviced.

Hi, Nick. I have a 55x900f that has started to go into a boop loop error. Sometimes it will make it past the initial setup where i can choose the language and network, but almost each time i push a command on the remote the tv cycles off and back on again. And then on the race occasion i do make it past the setup the TV just turns on and off repeatedly.
However, I am not showing any red blinking error codes on the front of the TV. Can you advise?
Jesse,
This is going to be another main board related failure. A lot of these 4k sets from Sony seem to all be plagued with similar type failures. Sometimes it is a software failure, sometimes it is a processor failure. I would suggest purchasing a replacement main board, it will resolve your issue.

I have same issue
I have an older xbr55x900A that I have recently changed the main board on. The red LED error code has gone away but I now have a problem that when I power it ON, the backlight comes on for about 2sec, then I hear a relay click, and the backlight goes out. The power remains on, but there is no picture at all. Any Ideas? What lead to the main board change in the first place was most likely a power arc from an HDMI port over driving that port (I think) - because it failed just after I inserted an HDMI device. Any ideas if I also need to change out the power boards, or does this sound like a ribbon cable problem? Thanks all!
Check the connector on the power supply board that links the power supply to the main board. One of the pins should be a BL-ERROR pin. Check to see if there is any voltage on it. If your TV is detecting a backlight error, you will see some voltage. If there are no Back-light errors then that wire will read 0 volts and indicate the issue is coming from somewhere else.
I guess something that would be also very important would be for us to know what the original error code was. That may help us understand what is going on now.
What about an XBR-X850D that works fine, then at random will shut off and restart. Sometime it will work for 5 minutes, sometimes for hours before "restarting".... Any thoughts?
Dwight,
I highly recommend a Factory reset first. If the issue persists, then a software update. If the issue still persists, you will need to have the main board either replaced or serviced.

I would recommend you purchase an amazon fire stick as it is about the same price, but is also an android based device just like the Sony tv's are. What this means is that you can control your Fire stick device using the Sony remote. Additionally I do personally believe the operating system for the Amazon fire stick is a bit better and easier to navigate than most other similar devices.

2. Press and hold Power button and (-) Volume button
3. Keep pressing the buttons while plugging the TV back to the mains
4. Keep pressing for 20 seconds or more till the small red LED turns into green.
5. Wait for few minutes till the TV resets itself
John,
Nice work, it's always nice to be able to resolve an issue that easily.
Pressing and holding for 20 seconds the volume down and power button while plugging in the TV will force a reset. In some instances such as yours it will fix simple software issues. When it comes to hardware issues however this won't work unfortunately.
I hope the fix lasts. If not it's probably a sign of a more serious underlying issue with the mainboard.

If you go under the system settings, there is an option to reset the tv to factory default. I would highly suggest doing that first. If that does not resolve the issue, I would then suggest performing a software update. If that still does not resolve the issue, then you will need to either send in your board for repair or find a replacement.

my sony xor-55x900e didnt turn on , then it did turn on but only showed sony and they the animated circles and turned off , then it turned on and got all the way to the channel menu and stayed on for a minute and then turned of again. can you help me?
Hello, Kairus1,
What you are describing is very common and just like the 900C the 900E TV has that exact same symptom which is a main board failure. This is something you would need to send in for repairs.
Check out our mail in repair and return service linked below for more details:
www.nickstvs.com/store/p2344/XBR-55X900E.html
for me, my sony xbr65x900c is working just fine... besides the screen flashing black. not even the entire screen though, certain points of the screen go black at completely random times, then come back. I have no clue what to do.
It sounds like you have LED strip failures. The symptoms you are describing for the LED failure however is not good news in the sense that there is no easy fix. The only way to properly repair the set would be to get the LED strips replaced or serviced and that is a very labor intensive and delicate operation for these sets. I would suggest contacting your local TV shop and seeing if they have experienced replacing these strips in the past and what kind of charges they would have for this type of repair.
I have a problem with 32wd759 model it started freezing on me while tv plays the channels
Phil,
I am not familiar with this model specifically but I would suggest a factory reset and software update if an update is available. If that does not resolve your issue, then you may need to replace the mainboard.
@@NicksTVRepair Already solve the issue I'll buy LG instead this one that I've bought I sent to diagnose but it will not solve the issue. Repair mens look uncertain about it.
I have a Sony A8G that after it sits and I turn it on it turns back off. Once its on it's fine until it sits.
I highly suggest resetting the TV to factory default and performing a software update asap if one is available. If the issue persists, you may have to replace the mainboard.
My tv goes through the on screen process like it is resetting, but after it finishes with the circle image and shows the Sony logo, the screen goes black and it plays a soft piano-type music.
It sounds like you did a force reset to your board. Have you tried updating/pairing it?
If not, check out the video linked below and give it a try:
ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
If that does not resolve the issue then you may need to have it fixed or replaced.
What about the led light is white doesnt blink but screen wont come on?
Okay, the screen won't come on. Does the backlight come on at all? meaning do you get a glow from the screen? Do you get any audio from the TV set? If the answer is NO to the above the first step I would suggest would be to try a factory reset. You can follow the Factory reset instructions from Sony's website linked below:
www.sony.com/electronics/support/articles/00159487
If that doesn't resolve it, then I suggest checking out our software update video which will demonstrate how to update the TV using a flash drive if the set doesn't turn on. The video linked below starts at 3:07 which is where we show how to download the software from the Sony website
ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
If that still doesn't work, then we suggest force updating the TV by changing the file name. Further instructions for this will be at the 5:20 times stamp which is linked below:
ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
Please let us know if either of these works for you, and if so which one resolved the issue.
If neither options resolve it, then please let us know as well. In that case, your mainboard has a failure that is severe enough that it will need to have components replaced and will have to be sent in for repair.
If you have any questions, just post a reply!
@@NicksTVRepair Thank you for the reply, tried all, also called SONY tv needs repair
I am having issue in KDL-43W800C of 5 time red led blinking.
I have replaced T CON board.
But still problem continues.
Based on the information we are aware of regarding the 5 blink code the issue could be either the panel, aka the screen, the T-con board, or the BMX board which is your main board. Since you have already replaced the T-con board we would suggest you try replacing the main board next as the Panel is going to be much to expensive to be worth replacing.
Unfortunately there is not more information or any further troubleshooting that we are aware of for this model as it is not a model that we commonly work with.
@@NicksTVRepair Thanks for the fast reply.
I observed that, after replacement of T con, firmware need to be updated. At that moment tv is working fine for some long time.
After turning on tv around 6 to 7 Hr when switchoff, it's not getting on.
I thought u get my point what I mean.
My XBR 65X900F comes on but the sony dosent show up and the power light stays solid white
We have been seeing more and more issues lately with the 900F mainboards. We have been fixing a few and what you have sounds like a common EMMC failure that we can fix.
If you want to give it a try with a used module online, go for it, there are still some cheap ones available out there, however, we have been hearing from customers that they tried purchasing boards first without success, I don't know why but there seems to be a lot of bad mainboards out there, so if replacing the mainboard doesn't work, just let us know and we can always just fix your original.

I have the KD55X8005C and it's stuck on the Google circles. Has been for hours. I tried a hard reset with the power and volume down buttons, I get the green led, release the buttons and nothing happens. Press the power button again and the circles are back. No welcome screen, no Sony logo, just the circles. Any ideas folks?
That's a mainboard failure.
@@NicksTVRepair thanks Nick. Expensive repair would you say?
Model no KD 49x7000d
It shows sony logo. And the screen oscillating then blank screen.
Help me
Kather, when you say the screen is oscillating, do you mean the screen is shaking/jittering? Do you ever get a blinking code or just the blank screen and nothing after that?
Because you do get the logo to appear on screen I think it is safe to rule out the screen and T-con board as being at fault. Most likely your main board is the cause of the issue, however since we do not actively service/fix that type of model I can't say I am extremely familiar with it. Based on my experience with other Sony models however I would put my money on replacing the main board.
If you have follow up questions, we may be better able to assist you if you contact us directly on our support email. It seems we don't always get reply notifications on UA-cam.

sony bravia kd 65x8505c blinking 7 tiems red . Merci
Je ne sais pas
But some TV particles Android logo can be stuck with move triggered parceled.
What do you mean exactly when you refer to the "move triggered parceled"?
My Sony bravia KD-55X7000D won't reset, erase or load at all with any steps listed online.
You most likely have to replace your mainboard then
Im not getting any blinking just Sony then colors an then black screen but power is on..Help pls if you see my comment
Jessica,
It seems you have a mainboard failure but there are a few tests you can do. I recommend turning the lights off and powering on the set. After the Sony logo and the Android logo go away and the black screen is all there is, does the screen glow at all or is it pitch black?
Are you able to turn the TV back off or do you have to unplug it?
Here are a few things you can try to fix it.
Unplug the TV from power, press and hold the volume down and power button on the buttons on the TV, not from the remote, and while still holding those buttons plug the TV back in.
Keep pressing those buttons until the TV turns on or the pilot light (standbylight) turns on green.
This will force a reset on your TV. If you can not get the reset to work, you can also try pairing your TV set.
Go to the sony support website and download the software for your TV set.
You can watch more details on how to do that here
ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
I have time-stamped it where you want to start watching.
Good luck
It turns on, goes to apps automatically and resets help I was told I need a new motherboard
A new board or to repair your original if new is not available or to expensive.
HI MY sony bravia tv just turns on went pass the logo it turns off again
Hello, this sounds like a main board issue. What specific model of TV is giving you trouble?
I have a 75x910c that is flashing bright and dark.
Would you have a video or can you find another video of someone else with similar symypoms to share with us?

Hi i have a sony xbr55x900f
Everything work for 45 minutes
Then it froze whit sound or back screen
And Android restart
And it work again for 30
Them froze or black screen again
And Android restart again
Raul,
I highly recommend you perform a factory reset and software update.
This is not always going to work depending on the level of your failure on the board but it is the only solution available aside from either replacing the mainboard, or sending it in for repair.
@@NicksTVRepair already done
Factory reset
But still freezing and reboot
Okay this is what worked for me, I tried holding down the power button and the down channel key on the tv And then plugging in my device, Several times It didn't work. So what I did was Hold the power button And the volume key And then plug my TV set in And it gave me is like a Halo circle With different colors.Then I unplugged my TV. I held the volume button And the power button then Turned my TV on and Waited till I saw the tv Cut on And cut off. The TV cycled a few times and it was fixed. You're going to have to try using the volume up or down key to see which one works,But holding the up-and-down channel key did nothing for my TV.I Hope that helps someone
This link below has a lot of information regarding force resets and factory resets.
Every year and model is different, so make sure to read through the information first to identify which button combination is the correct reset combo for your TV
www.sony.com/electronics/support/articles/00159487
it freezes on loading android logo
That's a very common mainboard failure. If you want to send in your mainboard for repair, we do service it and offer a 1 year warranty on the repair! Check the description for links and additional info!
After the Android logo, it goes black and get 3 red blinking lights.
According to my information, 3 blinks can be the following:
Main 5.0V failure [DC_ALERT]
Audio amp. protection [AUD_ERR]
Tuner or demodulator I2C No ACK [TU_DEMOD] [Note.1]
HDMI Switch/Equalizer I2C communication error [HDMI_EQ]
: Main board, : Speaker
So most likely the mainboard, with a chance the speakers are at fault. A simple test is to disconnect the speakers from the mainboard and power it up. No more 3 blinks with speakers disconnected then your speakers are the fault. Still get the 3 blinks with the speakers disconnected, then your mainboard is the fault.

XBR-55X990E has wide color bars red Green blue which alternate direction vertically and horizontally then turns red and shuts off.
I am guessing this is a main board problem, Have you experienced this ? Can you give me the correct board number ?
Any suggestions ?
I have not found any service info on this model and it is not listed in my service files.
Do you have a XBR-55X990E service manual ?
If you can help please give me your email address.
Hello,
That is a common failure we see for the 850E and 900E sony boards. In this video, we didn't cover that failure as we only talk about the 900C and 910C models which don't experience that issue.
That is a mainboard failure you are experiencing. If you can find a replacement mainboard, I would suggest you purchase it. If you are unable to find a replacement, we do offer a mail-in service for that problem exactly with a 1-year warranty on the repair.
