Hi Nick, I've tried everything mentioned in this video and yet no matter what, I still get the green & amber flashing occurring. If I leave it for 10 mins it starts playing this soft music but no picture and the leds are still flashing. I've left it like this for several hours and still nothing changes. I've even tried reseating the LED screen cable a couple of times. I should mention that I swapped out the main board with a known working used replacement as the previous one died. Since replacing it, I have not been able to get it to pair using any of the troubleshooting tips mentioned here.
This was perfectly explained been months with out a tv got a new board followed your instructions took a couple of times then bam!! Got a working tv couldn’t be more greatful thank you!
Glad it helped
Thank you a lot!!! You're the only person who made a detailead and easy to understand guide to pair the mainboard!
Glad I could help!
Hi! I just wanted to say that you really helped me big time with my KDL-50W800C with symptoms of checkered test mode patterns produced by T-CON. The procedure on renaming the file to get accepted by the TV is the key! Thank you so much!
Yes, it's a tricky step no one tells you about.
Used this video to Pair my replaced Main Board with my TV, Sony KD-49X8005c. It worked, thank you so much Nick! Saved my sanity!
Glad it helped!
Thanks a lot for your video. I was able to fix the loop boot on my sony xbr-65x810 tv. No one else shares this method, only you. Hats down to you, you are the best.
Glad it helped
I never knew the upgrade_loader rename trick. I've been repairing tvs for years and this is the first time a firmware install hasn't taken before, renamed and it took immediately. Dude you're awesome.
Glad I could help
Excellent guidance. Follow these instructions to the letter - including completing the pairing process a second time as Nick discusses at the 6:36 mark. Thanks, Nick.
You're very welcome! Thank you for the feedback :)
Great video! Without it, I couldn't save my 55x850c. Long story short, I had 7 blinking red light issue. I ordered main board from ebay, followed the instruction from video step by step. I was able to pair the new board with my old TV, however, it only had audio, no video after firmware upgrade. I disconnect and reconnect the ribbon cables and redo firmware couple times. And finally it booted up with audio and video! one tip: make sure the usb drive has the firmware file only. Every time the TV loads with usb drive, it'll create a folder on usb drive and the TV won't take firmware if there is folder in it. Thanks Nick! This is my first Sony TV and probably the last one as it's not relible
Glad to hear that was helpful. Yeah Sony sets are greate but indeed they do tend to have software issues. I really like their user interface and find it a lot easier to navigate than say LG or Samsung's new UI. But as you mentioned, they do and can have software issues and are a real pain when it comes to main board swaps or repairs.
Big thank-you for this info. Explained perfectly the flashing green/amber, as I had no screen display. Had to rename the USB file as explained, then everything worked. XBR-65X900F. Thanks again.
Glad it helped
Thank you nick from the bottom of my heart. Your video was tremendously helpful. I will also leave some information for any one who is using the kd 55x8500d model. After replacing the Tcon board there was no picture and no backlight. Only the green amber led. The TV was detecting the USB drive and was creating folders but update never started. Renaming did not work either. I tried about 10 times. I turned the tv on and could hear sound when I was pressed remote buttons. I could see normal dim white led signal. So I kept on pressing the input button on the remote till I could hear the static sound of the TV section. I inserted the USB drive keeping the original name of the pkg file and removing the folders that were created previously. After a few seconds the white dim led remained but the static sound stopped. I did not touch anything. After 5-10 minutes the white led started pulsing (not slow blinking). The white led was going to maximum brightness and then dimming again consistently. Somehow I felt like it was the upgrade process. It pulsed for 15 minutes and then turned off. I turned the TV on after a few minutes. No backlight no picture but I could hear the remote button press sound. I repeated the whole process again deleting the folders in the USB drive and inserting it when I hear the static. This time the pulsing took longer than before. Suddenly out of no where backlight started working and I could see the sony logo followed by the android loading screen. I cannot exactly tell for how long but it was less than an hour. The way the backlight and picture stopped working after the tcon replacement I though it would never work again.
Good work! This is why we insist that if it doesn't work at first, keep trying. Way to go and persevere through!
Glad to hear one less TV was tossed out this year.
I found your answer with a link to your video on the forum badcaps (which I've been a member of for a few years just like yourself). I tried for ages to force an update/upgrade through a USB stick but with no joy.
After watching your excellent video above, I just renamed the file on my USB stick and that forced the update/upgrade.
Seeing the word 'SONY' appear on the TV screen was just perfect. Thank you very much for the video and telling us the rename file name.
Thank you...
No problem! Yup patience and renaming the file. Those are the two most important pieces of the puzzle.
Thanks you for the “wait 6-8” hours! I actually only waited 30 minutes, came back , and it said update complete on he screen. This worked on a Kdl-70w850b. . Thank you Nick!
Nice, glad it helped.
Hi Mate, where did you get update software? I just notice that SONY terminate the download for 55W800b.
Just found your video and replaced my motherboard and ran the updates. The pairing procedure followed your video to the letter. If not for your video I would have been defeated but your information prepared me for the failures and allowed me to continue on. In the end, I had to rename the file as directed and viola! it worked. Although, the update took only about 20 minutes +/- before the TV turned on and the install was complete, I was afraid to do anything for the remainder of the hour as I did not want to cause any damage. Thank you. You saved me a new TV and or the cost of labor and a service call.
Happy to hear I was able to help!
Hey man ! I was searching everyday for someone that explain this método from the simple form. And you was so quick and objective. Thanks!
Got 01 subscriber
Glad you liked it!
Thank you so much. You saved me a lot of money. Sony wanted to replace the mainboard again!
Glad I could help!
Thanks Nick for the services your provided for me.... NJ TV-Computers. one point. Almost always amber-green flashes at first with usb in. just walk away, seconds or minutes slow white blinking will begin. Like you said if all hardware ok.. firmware install will complete in about 45 min, set will power on when updated completes. thanks again.
Glad to help
Thanks for video. Managed to get my Kd-55x8509c working following your video. Factory reset wasnt working and just got to android screen and reset. So what I did was unplug all leads from the main board. I then reconnected them all. This then put the tv into bootloader mode. Green and amber flashing lights. I then downloaded the latest firmware from sony and renamed it as you did. Plugged in tv and it started flashing white. After 30 minutes I heard sound butno picture. So I unplugged tv and plugged in again and the white light started again this time took full hour and worked. So before you go buying new main board or repair service try this.
Nice, that's great to hear! Yes it is very rare but there is a chance that your mainboard may not in fact need servicing, but instead just to be updated/paired.
Thank you, Nick, great video, I followed all your steps including downloading the firmware. Everyone I could not get the Firmware to install until I followed the last try which was to leave the usb drive in and wait 6 to 8 hours while the green and amber lights were on and after about 20 minutes the light turned white and the firmware installed and everything works.
Great to hear!
This was really helpful, thanks!
I wanted to add that in my case, the pairing procedure worked fine after swapping my motherboard, however if I had followed these instructions to the T I would have been pulling my hair out.
The update files can be quite large, the one for my 65x930d was about 1.5GB. It takes time for the TV to read/copy/validate this large file off a flash drive. When I booted the TV up with the drive inserted (using the standard filename, not upgrade_loader.pkg), it would boot up with the green/amber flashing light, however I noticed the USB drive was still actively reading while the TV lights flashed green/amber. I followed these instructions and initially powered down, then went to check the drive, and noticed the TV had created an Android and LOST.DIR directory, which tells me Android on the TV was booting and reading the drive. I tried again and just let it sit for a while, with the green/amber flashing light, to let it finish reading off the drive (likely copying/verifying the package, like a typical Android OS update), and the pairing process began with the white pulsing light as expected after the drive stopped reading. Using a fast flash drive on the USB3 port on my TV, it took maybe 5-10 mins of green/amber flashing while reading the drive before it finished reading the file and actually started the process.
Just wanted to point out that people may want to give it a bit more time. I'd suggest the recommendation be to pull the plug and try again if the TV is flashing green/amber only, but only if it continues to do so after the drive has stopped reading. The final "leave it for 6-8 hours" instruction would cover it as well, but may not be necessary.
Works for me !!... only have to rename to upgrade and wow!!! thank you!!!
Glad it helped
Renamed flash drive what name is iit
hi Nick! thank you for nice video, just want to confirm to everybody who replaced mainboard and disconnect LVDS cables and have situation with red green blue black/white chess board screen with music playing - YES, you absolutely right, cables is the problem ! i tried connecting disconnecting few times, they dont look as damaged, so you can think they OK, but after i took set of cables from another tv same model, red green blue screen is gone and tv starts normally. my model was xbr-55x900f, so looks like those cables can be damaged internally very easily, thank you Nick!
exactly. 9 times out of 10 that's the issue if the pairing is not working.
First of all, my thanks for your immense help, you have no idea how much you helped me with this video, here in Brazil this motherboard is extremely expensive, so with this video I was able to repair it and it saved me about U$$500 and this in Brazil is a very high value, so thank you very much 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
We are so glad our video helped you! We appreciate your feedback, thank you.

Hi Nick....thanks a lot for posting this amazing video, it helped me to get my tv repaired!! I searched on internet for two days and tried many different ways on how to restore the firmware on my tv but nothing wokked until I found your Video so thanks a lot one more time you are the best!!
That's fantastic to hear! I'm very glad your TV is up and running again.
Thank you for reaching out to us ✌
Please can you send me the firmware
@@samuelacquah2051 the firmware is on Sony's website. Just search for your model number, go to support, go to download and find firmware. This is just from memory.
Thanks a lot man. In my KD-60XF8305 worked last solution to wait longer time with pendrive connected.
That is wonderful news! I'm glad this helped you.
Thanks, updated the main board using your video.
Glad it helped
Best video for repair this boot loop error of android TV, thanks
Thank you for the feedback! We appreciate it
So helpful, TV back up and running.
Happy to hear it
Excelente vídeo, agradezco mucho te ayuda me permitió entender como se actualiza el software, saludos
de nada
Thanks for your video. My XBR-65X900C Sony 4K TV apparently needs to use this process when disconnecting LVDS ribbons even though the Android update is already installed on the TV. I re-applied the updated from the USB drive and after 2 trials, it worked. I do not know why it needs to be applied two times, but the important thin is that it works. The green and yellow lights are gone and I have the TV showing image again. I damaged the LVDS ribbons because I was thinking that the green and yellow blinking lights were an indication of bad LVDS ribbon connection. So I was disconnecting and connecting them back without any results until I damaged it. I saw this video and after buying a new set of LVDS ribbon, I connected it only once, got the green and amber flashing light, but this time I figured that I needed to apply the latest update from the USB drive again. Did it twice, but it finally work. You are a lifesaver, thanks you.
No problem, happy we were able to help.
Sometimes if you power on the TV with the ribbons disconnected you need to pair the board back to the screen. This is why we like to refer it to a pairing procedure more than software update. You aren't truly updating the set, as you mentioned your board already had the most up to date software.
Thank you so much, helped me solve this issue quickly.
Glad it helped!
thanks helped me pair a new replacement board on my sony bravia
Glad I could help
Hi Nick my XBR-65X850c starts and shows the sony logo and stays on it for an hr. Them automatically turns off and on with the white led light. But the screen stays blank. Then turns on displaying the sony logo again. Hard reset doesn't work either. Any advice will be appreciated. Thanks
Sorry but that means you have to get your mainboard fixed. It sounds like the EMMC chip has degraded and needs to be replaced. For more info on that process, you can check out this video here

@@NicksTVRepair Thank you
Nick - just wanted to thank you! Someone in our neighborhood was giving away their 85” after they tried to fix it by replacing a bunch of boards. I’ve had some luck repairing Samsungs in the past and thought I’d give this Sony a try. After some searching I found this detailed video and was able to get it working for zero $. I tried everything in order and the trick for me was renaming of the firmware file and then reseat the ribbon cables. This tv will be a great Xmas gift to a good family friend of ours.
Glad this helped!
Merry xmas
@@NicksTVRepair I used it without renaming and it worked.
God bless you. Thanks you sooooooo much.Very helpful video. Thanksssss👍👍👍
Glad you found it useful!
Colin here...Thanks again Nick for helping me with my motherboard replacement update issues! I couldn't get it to pair with just plugging the TV in as shown in this video. It would flash Amber/green every time! I was emailing Nick directly and he was prompt at his replies and very helpful. I also searched all over and tried everything I could find online. I tried and tried different things just winging it and got it working by a hard restart with the USB stick plugged in, then after the second hard reset it worked! What I did: Left tv unplugged and held power for one minute to clear capacitors, fresh update installed to USB stick and changing the file name to upgrade_loader.pkg, plugged in USB stick with power still unplugged, held down the power button, plugged in TV with power button still held, kept holding power button until green light popped on, released power button, it then clicked with amber/green again, left the TV plugged in then held power button again until the TV clicked off, kept holding the power button until the green light popped on again, released power button, and then finally the white light started pulsing, update started! Took only a couple minutes of leaving the TV alone where it then powered up normally and showed the setup screen! I was soo close to return the motherboard to the seller from ebay and buy a new TV. I even had it at the post office counter all repackaged for shipping quotes, but persisted and tried once more. Another TV saved thanks to you Nick! Cheers!!
Colin, I am very happy to hear you got your set back up and running.
I am surprised more sellers of these parts don't have instructions or at least provide you with a flashdrive.
These sets are very nice but they sure are a pain to service.
Is it just the power button or power and volume down?
I think it was the power and volume down actually. Are you having troubles stuck on amber green flashing?
@@FirstGenToyMachine mine will flash green and then flash white and I can see the flash drive working but then it goes back to a black screen with that soft music once it turns on and off a couple times.
Is it important to unplug the tv from the mother board or is the wall good enough?
Hi Nick! Thanks for Share this videos. I can upgrade new main for Sony KD-65X750F same problem. 🙏🏻🤠
Are you referring to an issue pairing your board? What was the original issue with the set, and did you purchase a new board or send your board in for repair? What symptoms are you getting now?
I have the XBR-55X900E, I was getting 4 RED flashes. Assuming there was an issue with the LED Controller board, I replaced it, Still had the 4 RED flashes. disconnected the LED Controller, still 4 flashes, So I purchased a new Control Board. I had the Green/Amber flashes requiring a Firmware Update, Did exactly as you said, but after about 15 mins, the 4 red flashes came back. Now I am scratching my head as to what it could be, mind you I have no multi meter skills to dig even deeper. I would greatly appreciate any help you may offer if kindly would.
Thank you, and I have to say your videos are absolutely on point and get results.
Hello,
You are in luck, we have a video covering exactly that issue
ua-cam.com/video/T3VRvQUB_DQ/v-deo.html
Good luck
Awesome video Nick, thank you very much. Im soo close to solving my T.V issues. I had the 4 circles, and replaced the B-Board. Powered up and everything worked for 5-10 mins, then shutdown and went to a green/orange flashing led. I did the software update via USB and the LED which was previously Green/Orange changed to a slow pulsing white and slow spa music playing, however now I have no video, just sound. Unplugged replugged, hard reset(power,vol-) and doing the software update steps again all lead to the same outcome. Did I miss a step anywhere?
Did you maybe break one of the tabs on the side of one of the ribbons? Double check and make sure you are lining up the ribbon correctly.
Thank you
You are very welcome
Replaced my main board on my KD65X9000F after home screen boot loop made it unusable. Hard reset and firmware force did not work.
Once board was replaced. Took about 2hrs of trying. Power on and off. Could hear the spa music when tv buttons were pressed but green and amber were consistently flashing.
Usb stick was 16gb Fat32 with filename to upgrade_loaded.pkg
Started to rotate usb ports on tv every time I turned on and turned off the tv at the wall when it didn’t read. When turning on, waiting for the tv to boot itself.
Finally got the slow pulsing white led and about 15mins later, solid blue then android icons appeared.
First time setup had been reached.
Thanks to all comments and Nick especially on this video that said to persist with the painful pairing of a new main board.
Yes, it's insane. you can do everything correctly and it still doesn't work until you do it like 3 times. We have had some weird ones like that.
One tip though is if you get the music and no picture, that could be because one of the ribbons is not making good contact and reseating them might help.
Great instructional video! I have a XBR-55X900E that occasionally re-booted randomly. Now, months later, it re-boots - turns off - turns on, reboots, endlessly, but only if the internal wi-fi is toggled on or an ethernet cable is plugged in. I can use the TV but without network functions it is no longer a Smart TV. When changing the main board, to a new one, the serial number and other data must be changed through the service menu correct? Are these usually ball-grid array solder problems on the main SoC? Or a fault within the SoC itself?
The serial number and other data doesn't need to be changed, you can keep it as is and it won't affect the TV. If you haven't already purchased a new board, I highly suggest purchasing a fire TV stick instead, it will be much easier and cheaper to turn your TV back into a smart TV than replacing the mainboard.
There are sometimes issues with one of the video processing chips with this model TV, but not always. And generally it's not a cracked solder issue, usually it's the chip itself that has become defective and needs to be replaced.
@@NicksTVRepair Thanks for the reply. I considered the Fire TV Stick, but I have an XBOXone and a Blu-Ray player occupying the enhanced HDMI ports. The Fire stick would have to be used on one of the other HDMI ports where HDR is not possible. For now I am using the apps on the other devices with HDR and am using the TV as just a display device for now. Considering getting a new TV from what I know now, and using this 900E with a Fire TV stick for a bedroom or rec-room. I appreciate the work you do in trying to keep TV's out of the dumpsters. Too bad manufacturers don't have more reliable products to do their part in reducing pollution but they are only interested in selling more TV's.
@Nick's TV Repair Thanks for your reply Nicki.
I tell you to connect the T-CON as it was but the screen has not been paired with the plate. Check the power supply board with a multimeter and there are 4 TCON_VCC12 pins and 1 TCON_ON pin but I measured voltage on those pins but I don't have 12 Volts; I measured the cable that goes from the source to the T-CON, 3 gray cables and 1 white but in those pins I do not have 12 Volts; in the T-CON what voltages should I measure.
I bought a new T-CON to try and rule out that it is the T-CON that was damaged, when I turned on the TV, I hope it will arrive in a couple of days and I will tell you how it went.
Thanks for your help.
If you are missing the 12v then you may have an issue with the mainboard.
Nick,
XBR-65X850D
I am at the 6-8hr wait, of your instructions.
Green and Amber were flashing for app. 15min, then pilot changed to White pulsing for another app. 15min.
Then back the green and amber flashing for app. 15min.
Then it went out altogether.
That total process took about an hr.
Now there is no front light, but Optical Output is occasionally turning on, then going out...every min. or so.
Is it still in the pairing process ?
[Update]
Since it stayed that way for about 2 total hrs, I decided to hit the Power Button (FP). The White pulsing light started up again, for 30min or so, and I got a display saying the Update was complete
(or something similar).
I'm back to my original issue, horizontal line across the middle and intermittent foldover from that line down thru the bottom half of the picture (Bad LCD Panel).
Question
Are the Main and Tcon pairing together separate from the LCD Panel ? I ask because I would like to sell the pair.
Or, does the buyer have to do the same thing I just did (pairing) Main, Tcon and Panel.
Based on the information provided, you most likely have a perfectly functional main board and T-con and simply have a defective screen.
You would be safe selling the modules knowing they are not the cause of the failure you are experiencing.
These main boards are not known for causing these lines.
Now selling the main board with the T-con will decrease the chance that the buyer will need to pair them together. I can't guarantee that will be the case, but I do believe that if both are indeed sold together, the odds of a pairing update being necessary will be almost 0.
thank you
You're welcome
Hi thanks for a succinct guide. My tv is KD-43X8305c stuck in a boot loop. I have tried all your proposed solutions including renaming the file. The TV now says 'updating' with a progress bar, but when the progress bar completes the TV restarts the whole 'updating' process begins again. That has being going on for the past 7 hours. Is my motherboard dead and only a replacement motherboard will work? Thanks.
Unfortunately that is correct, at this point the software on your main board is most likely corrupted to the point that a software update won't be enough to correct the issue. The board will either need to be repaired on a component level or replaced.
Hello Nick, first of all I would like to ask you is this the same procedure for KD-65XF9005 ? And second question is about first step during pairing. You pluged USB with sony firmware ? I changed a mainboard in my bravia and have a green, red, blue and chessboard loop on screen.
Sounds like the LVDS ribbon is not properly seated. I hightly recommend you disconnect and reconnect the ribbon going from the main board to the T-con.
I am not familiar with the KD-65XF9005 but can only assume it follows similar rules.
Hello Nick. my friend changed the main board from a broken xbr-55x805e to a new xbr-55x800e main board and it worked perfectly but he can't remember which of the two main boards he downloaded software for. My question is if I should download the software for the xbr-55x805e, which is my TV, or should I download the software for the xbr-55x800e, which is the main board that I now install?
Paulo,
If the boards are interchangeable then the software is probably the same.
Nick, I have the XBR-55X900F and was hoping you could help determine if the main board is malfunctioning. The TV boots up into android startup screen (no Sony logo appears), then it goes to the Sony Home screen for about 5-7 seconds, goes blank, then back to Home screen again, repeats this cycle multiple times, then finally the screen goes blank after a couple minutes, the power light stays on and is white, never changes colors or no blinking either. I think the EMMC chip on the main board might be bad, but wanted to hear your thoughts on the problem. Thanks for you advise in advance. Marc
Hey Marc,
It sure does sound like an EMMC fault to me, but I would suggest you try a factory reset and software update first to see if you can buy yourself a bit more time.
To factory reset the TV unplug it from the wall and wait at least 10 seconds. Then using the buttons on the back of the TV, press and hold the volume down and power and keep them pressed in as you plug the TV back to power. Keep those pressed in for at least 10-15 seconds or until the standby light in the bottom from of the TV lights up green.
Then you can release. This should reset everything back to default and hopefully get you back and running for a bit longer and should allow you to get a software update going if you aren't already on the newest version software.
If this does not resolve the issue, then you will have to get the board replaced or repaired.
We have a service for this one which I will link below:

Wow that’s a lot of work but great job explaining it! Sony’s latest update has got my X900F rebooting almost every time I power it up from sleep and it will occasionally reboot randomly (usually once every few days for this one) too so I was looking into replacing the main board. I’m still dreading the idea of doing so because while I have built computers since I was a kid, I’ve never worked with a TV before, and I can’t sleep without TV at night either so I would have to start way early in the morning if I hit the 6-8 hours point.
What is it with Sony lately? Sony replaced my X900E I bought in 2017 with this thing like 10 months later after some panel issues and now my TV that was working flawlessly before the Android 9 updates is rebooting at least once a day. Is there a company that is even reliable these days? I hear that Samsung and LG are just as bad and TCL and Vizio are much worse. It’s crazy we spend $1000+ on something that doesn’t last more than a few years.
Robert,
I recommend a factory reset, but if you do still have issues then I would recommend you replace the mainboard.
As for these issues, you are correct no company is safe these days, they all have issues somewhere.
@@NicksTVRepair Hi Nick, thanks for the response!
I had already done a factory reset so I was feeling a bit stuck. I did check reddit though and enabling Simple IP Control actually fixed it.

Apparently this has been an issue for a few firmware revisions now and instead of fixing it, Sony is telling people to do this. 🤦♂️
I tell ya, that’s the last time I update my TV. I have an Nvidia Shield TV and should have known better but people were touting improved HDR brightness, one of my biggest complaints about this TV, and I fell for it.
Thanks Nicky for the explanation, in my case when I turned on my TV xbr-49x839C I did not connect the LVDS cables or the power to the T-COM, but I saw the green and orange lights come out when I turned it on, so I paid and connected the cables LVDS and the green and orange lights remained, I have done your thing but when I put the USB memory and turn on the TV a white LED turns on but it does not blink as in your video, it turns on and off slowly until in a few moments a light appears BLUE light that stays for a few seconds and turns off. After another few seconds, the green and orange light appears again for about 5 or 8 minutes until the lights finally turn off, if I turn on the TV with the remote control I get the sony startup sound but I have no video at all. What could be happening with my TV? Any idea how I could fix that.
Thanks
When disconnecting the LVDS ribbons from the mainboard to the T-con and powering on the set, this will cause the orange and green light to come on. This is because your mainboard is now no longer paired with your TV set. This is normal and will happen every time you power on the set with the ribbons disconnected.
You need to reconnect those and pair the board using the instructions in the video. If the picture is still black after doing so, then either you have damaged your ribbons, or they are not seated properly.
There is a chance your mainboard is defective as well, but since I have no information regarding the history of the board you have, that would be just a guess.
If you have any more questions, please post a new comment instead of a reply as I don't get a notification for replies, only new comments.
@@NicksTVRepair Thanks for your reply Nicki.
I tell you to connect the T-CON as it was but the screen has not been paired with the plate. Check the power supply board with a multimeter and there are 4 TCON_VCC12 pins and 1 TCON_ON pin but I measured voltage on those pins but I don't have 12 Volts; I measured the cable that goes from the source to the T-CON, 3 gray cables and 1 white but in those pins I do not have 12 Volts; in the T-CON what voltages should I measure.
I bought a new T-CON to try and rule out that it is the T-CON that was damaged, when I turned on the TV, I hope it will arrive in a couple of days and I will tell you how it went.
Thanks for your help.
Just found this video did everything like you said. The standby light is still white but screen is going from green red blue and white do I need to do anything else?
That means the ribbons aren't plugged in correctly, but I saw your follow up nice work on getting it working!
So my 65x900E had the no power/no lights issue. I replaced the Power Board, and it worked for a week. So, I replaced the main board and the power board, and I still got the no power/no lights issue. I got a forth power board, and still no power/no lights (nothing, with any combo of the 2 Main Boards and 3 good Power Control Boards). My power brick tests good. I think the Power Board tests good. The ebay seller of the Main Board said it tested good before they shipped it. After watching your video I'm wondering if it's a cableing issue, or as I originally suspected my 2nd Power Board is no good in-spite of what the seller says. What are your thoughts?
There is a chance the cables could be the issue, it is also possible the boards you are receiving are bad.
Of course I do suggest you disconnect and reconnect all cables, wires and ribbons to ensure proper contact. If that does not resolve the problem I would suggest doing voltage checks and making sure your mainboard is getting power from the power board.
If proper consistent voltage is being supplied, then your mainboard is defective and the replacement mainboard is also most likely defective. You could always try to force an update as well to resolve the issue with the mainboard but of course if the mainboard is truly defective, this won't help. You can check out our pairing procedure video below for more info on that:
ua-cam.com/video/3kYPjIHt8Lc/v-deo.html
If you are not getting the proper output voltage from the power board, then most likely it is at fault, or the power brick could also be at fault. Now keep in mind the power brick cables could also be making intermittent contact and could also be at fault, we have seen that happen.
If you are unable to determine which part of the system is causing your problems, I would not be able to assist you further with online communication and would then suggest you send in your power brick, power supply board, and mainboard to our repair facility and have us take a look at it. We would be able to check each part individually and confirm functionality for you and of course fix which ever part is found to be defective.
If you do want to send in your parts to have us check them out, make sure to send us an email first and we will let you know what steps you need to take to get started. Our contact info is linked below:

Is this something that will work for sony xbr65x900a I had some picture issues so i replaced the tcon board but now it doesnt turn on or anything and the new tcon is tested and good, I tried putting the old one back and even that one doesnt turn it on anymore and it was before
Per the title this is for the models ending with the letter C,D,E, and F. The A, and B are a bit different and the same goes for the G and later models. While you may need to pair your TV the process will not be entirely the same and may require slightly different steps.
I do not have info on the A and B but do plan on making a video in the future for the newer ones which are the G and later. Sorry.
Would this procedure be the same for an XBR-65A8G? I found the XBR-65A8F as compatible with my A8Gs firmware update.
It should effectively be the same. I'd give it a shot.
Hi, I have a xbr-65x900e that died and I am replacing the main board with one from an xbr-49x900e set with the same numbers on the board. Will it work after pairing or is there another step to get it to work on a 65inch tv? I have heard that it may go into a service mode blindly and I will be unable to see how to navigate. Any experience putting a board with the same numbers from a different size tv?
Yup it sure will! You won't have any navigational issues what so ever. You can toss a 75" in a 49" or a 55" in a 65", they are all the same board and you won't have any problems what so ever as long as all those models are the 900E series.
Regardless of the main board being from the same identical set or a different set, you may still need to pair the main board as shown in the video.
We fix these main boards, and we fix all sizes for the 900E and the 850E. We have 1 XBR-49X900E TV that we use to live test all of those different models and sizes as long as it ends with 850E or 900E and they all display properly on our screen.
I followed this a couple of years ago when my sony bravia kd 49x8005c got stuck in a boot loop and it fixed it.
Unfortunately it wouldn’t come on a couple of days ago and was just getting a blinking red light.
I followed this again trying to reload the software and after 5 or so minutes of the pulsing white light it goes to a steady blue/purple light.
Any ideas?
It is very important for you to tell me exactly how many times the red light was blinking. The light can blink 2, 3, 4, 5, 6,7, or 8 times. All of which will indicate a differnet fault with the TV. It is important you don't guess or think it maybe might be this amount of times. It needs to be 100% exact.
Based on your answer I can tell you what you need to do to fix the TV.
If you can't remember then you will most likely have to replace the mainboard first or send it in for repair, and then hope that was the issue from the get go. If it is not the issue from the get go we will then have to count the amount of red blinks after replacing the mainboard and start again from there.
What’s the device with the green amber light on it and do I need it to pair the TV?
Green amber means pairing is needed yes.
Came home from vacation back in March to a totally dead tv. Swapped out the power board, still dead; swapped out the main board, sound but no picture and firmware update wouldn’t work via usb; put in a new t con and tried to update firmware again and changed the file name as suggested...still nothing but nice ambient music. Nick, I tried the 3x routines to no avail, the redo ribbon connections to no avail, the total resting of the tv for 6-8 hours....NOTHING is working!!! I know you say to be patient, but for how long? If I have to buy a new tv, what brand should I get that is reliable and easily fixed if something goes wrong?
Melissa,
I would suggest you install the original T-con board back into your TV as well as your original power supply as try the updating process once more. If you have already made sure to change the name of the file on the flash drive and have no issues with the update taking, but still have black screen at the end of the pairing, I would then suggest re-seating the ribbons and trying again even if they look perfect.
As for a new TV I would suggest LG OLED models as they are the best picture available out there but do come with a heavy price tag. For second best, Samsung QLED would be the next best.
Let us know if you have any questions.
Thank you
Hi Nick, I Have an Xbr65X900C that got struck by lightning. I was told to replace the main board after a diagnosis. It took some time to find the board but when I bored up the tv with the new board it powers on but the screen remains black. I followed your video and I think I’m in the second pairing phase. It’s blinking white like you said, so how long should the rest of the pairing process take. The screen is still black at this time.
As the video suggests, the pairing can either take 1 hour, or two 30 minute periods.
If the screen is still black after pairing the module, you will need to remove power from the TV, disconnect the ribbons and reconnect them. They most likely are not seated properly. From there turn everything back on and either the set will work or the pairing will need to be performed again.
Nick's TV Repair hey Nick, thanks so much for getting back, but i actually got it working a few days ago. I just had to repeat the process like you said and now it’s fully functioning. Your video was what got it working 👍👍
I have a Bravia XBR-65x850B that I replaced the power and main boards. It is blinking green and orange when I press the power button. Does this method support this model of TV? The Sony site says I need to update the firmware from the TV menu but the screen is not turning on. I tried the method you show but it is not working. I have reseated the ribbon cables and they seem like they are in correctly and not damaged. Thank you for the video - quite helpful.
Nevermind, I had to put the firmware in the folder that was in the zip file, not directly i the root of the USB. Now my video is all garbled though but you got me successfully powered on. Thank you so much.
For the garbled video, you may have an issue either with one of the ribbons, or one of the parts replaced may have some sort of defect.
What was the original issue with the TV set prior to the repair?
@@NicksTVRepair The tv turned off and the red light was wa 8 times. Then it would no longer turn on. I first replaced the power board and that did not help. Now I am trying the main board but getting the garbled video. I did reseat the 2 ribbon cables and they don't appear to be damaged.
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.
Hey nick
I have a sony bravia kd65 a1 oled and the red led is 4 times blinking.
I did a hardreset 10 times. No results.
Do you have an idea which board is broken?
Thank you ver much :)
in my experience 4 blinks is bad backlight which means for your TV you would need to replace the screen since the backlight is built inside the screen for OLED. Long story short 4 blinks for OLED means you will have to buy a new TV unfortunately.
Sorry :(
Please get a second opinion from a local shop that can lay eyes on it and do a full diag in case I am wrong.
Hey, I found your video via a reddit forum after searching for a fix to 4 flashing red lights. I tried the usb with the renamed file and I got the updating screen. Then it stopped and tv blank again, back to red lights. I tried again and now the usb flashes but no update starts, no update screen appeared and no white flashing lights? Do I just leave it for 8 hours and hope or is there no point if I don't get the initial white lights and update screen again?
Hi
thanks for the Video

Hello! I have the XBR 65x850c, which like many others has the "blue splotches on white color" issue. I figured I'd try to disconnect the TCON board then reconnected it, while getting the part number. The TV powers up, the backlights turn on (with a violet/blue color), and the diagnostic turns on with white. No picture or menu displayed. I'm reflashing the TV with upgrade_loader.pkg, and seeing what happens. Any advice on what else I should do? (I noticed that the TCONN board likely should have had thermal grease or a thermal pad between the chip and head spreader, but there is nothing. The TCONN board makes a high pitched buzzing noise when on)
Hello Matt,
You stated in your message
"I have the XBR 65x850c, which like many others has the "blue splotches on white color" issue"
We have actually never heard of this issue before. Would you have a picture or a video you could link us to so that we may get a visual of what you are reffering to.
As for the T-con, that is correct there should be a thermal pad. We have occasionally seen thermal pads missing from TV's or the pads not being placed properly and thus not doing their jobs correctly thus increasing the chance for us to see it fail.
I would suggest doing the software update per the video but if issues still keep happening, replacement of the T-con first will be a much easier and cheaper alternative.
If that still does not resolve the issue however, a picture of the issue or video would help us greatly understand what you are reffering to.
As for the buzzing sound, we have heard buzzing from our T-cons in our test sets, some buzzing is okay. Very loud buzzing may be an indication of failure however.
@@NicksTVRepair thanks for the replay! I'll give you a picture of the white test screen and the color bar test screen (if the problem persists) once I get the replacement TCON board installed. Lots of complaints on Sony's support forum for my particular model having this issue. Sony has done nothing to address it, and this is only 2015 model- spent $1500 on this tv!
Nick, i just replaced my main board and LVDS ribbon cables on my X900F. I was able to get the latest firmware from Sony and rename it upgrade_loader as suggested in your video, but I only have back light with no video or GUI. I hear audio, but there is no video. This is the third main board I have tried, including my original. I also changed out the TCON board, but I sent both the main board and TCON board back as it was doing the exact same thing. Does this sound like a bad screen/panel? All of the symptoms were similar however, I was getting the full screen single colors and checkerboard pattern with my original main board, original TCON, and original LVDS cables, but I could not get the firmware to update in this situation. Any suggestions?
Based on the information provided your screen is most likely in proper working condition and the issue lies with improper pairing or data transfer. It is very possible your ribbons are not seated properly as that is generally the most likely cause of these symptoms. I suggest you double check your connections on the T-con board both the ribbons going to the panel as well as the ones going to the main board, and finally the wired connections as well.
Recheck all of those and try powering back up. You may still need to perform the pairing once again however since the main board may not have paired properly due to the improper contact of the ribbons and or cables.
Per the video, it is also possible to do everything correctly and still not get proper results. If the proper results still don't appear after reseating all the cables and ribbons, you can also try a soft reset with the flash drive plugged in.
The instructions for a soft reset are linked below:
www.sony.com/electronics/support/articles/00159487
@@NicksTVRepair Nick, thanks for the reply but I don't see any mention of a soft reset in the link. Is this the forced factory reset or power reset linked in the url? I have already done both power reset and the forced factory reset, but not with the firmware USB plugged in. I will double check all of the cables to be sure they are connected properly. So far I have not messed with the cables going to the panel from the TCON board. These things seem way too sensitive to be practical/reasonable connectors for any amount of time. I had a technician come over to look at my TV and he only replaced the mainboard with the exact same symptom. I feel like he really didn't want to help after one thing did not fix my issue. I asked him to tell me specifically what the problem was, power supply, fuse, shorted circuit, TCON, main board, LED driver board, various bad cables, or a bad panel, but he just wanted this to be simple and easy board swap, which it wasn't going to be as I explained to him in great detail . I thanked him and told him I would try to figure it out myself. He wasn't really interested in finding the root cause of the problem.
Thanks very much, NICKSTVS. Do you imagine how you helped with this video. It really saved me. i had spent months trying to fix a new motherboard in my TV
Glad it helped!
If the display model is different, can it not work? For example, the model I have is display panel SYV5541. However, sometimes it is the same model TV, but there is also a model of display panel V550QWME08. Is there a difference between the model of the main board and the display panel?
there should not be as long as the model of the TV is the same
Hi Nick. My TV had the 5 times red blinking issue. So I got a new T-CON board. I had the green and amber light.
I followed the steps in the video. After changing the file name to upgrade_loader.pkg, I got the white pulsing light, after a few minutes, I got a single blue pulse. And then a bright white to dim white transition. The LED indicator stays that way. The backlight is turned on, there is nothing on the screen. And I hear some mild music from the speakers. I can use the TV remote to change the speaker volume. But there is nothing in the screen.
I tried the pairing multiple times and also bought a new LVDS cable, but the behaviour is exactly the same as explained above.
Would really appreciate any suggestion.
Thanks.
Try reseatign the ribbons again. Typically this fault is due to improper contact with the ribbons.
Also make sure to check both the ribbons that go from the mainboard to the T-con as well as from the T-con to the screen circuit boards.
If you still have issues after that, then I am unsure what else could be the fault. It's possible your mainboard could be affected if you have an 850E 900E or one of the 2018 models
Sony 55x8509c back to doing bootloop again. Followed same procedures as before and it seems to be doing the update however the led light will flash white on and off and the do not remove plug picture is on the screen with the blue circular arrow. After about 30 minutes the led flashed purple then reset and same led white flash and do not unplug. Has done this 3 times now?. What does the purple led light mean?. thanks.
on closer inspection its a dark blue led. Does this mean update failed?
The dark blue light almost violet is normal as long as it doesn't stay stuck on it. If it stays stuck on it then you have a crictical software fault which typically means a new EMMC chip will need to be installed. However if the pairing keeps occuring endlessly as well, then it would still mean you have a software fault same thing will need to happen, new emmc with fresh software.
Hello ...excuse me i have a questio ...i change t-con of my tv kd-55xe8505 55t36-c04 with t-con kd-65xe8505 55t36-c04....i have update the t-con following your video...the update it work but the screen is dark with sound...where is the problem? With old t-con i se something with the new it's all dark....the t-con is the same ...do you think the t-con from 65 inchs is not good for 55? Thanks in advance
You can not use a T-con from a 65" in a 55" TV. That won't work. You need to exact same replacement board.
Is it normal for some updates to be a .bin instead of a .pkg? I downloaded directly from Sony and their guide confirms the download name as well as the update folder but the file itself isn't mentioned on the guide, I'm just noticing the file itself is .bin while others are .pkg
Hello,
What file are you looking at for which TV?
Hi Nick,
My 49X900F needed a new t-con board which I replaced. That seemed to fix the problem of no picture and everything seemed to be working great with one exception, the green and amber flashing light. After doing some research I learned that the way to fix that was to do the usb update. I downloaded the software to a flash drive and re-named the file as you recommend. The update started and seemed to be going along just fine but at some point the tv shut down and did not power back up. I waited quite a while before trying to power it up manually. When I did it would not respond at all. The only sign of life is a green light that I get when holding the power and volume down buttons on the back of the set and then plugging in the pwr. cord, nothing happens after that. Assuming that the main board was the culprit I've ordered a replacement. I'm concerned though that the same thing might happen. Any thoughts/advice?
You most likely had a mainboard failure about to happen. The update wouldn't cause a failure like that unless your hardware was already defective. It should be fine to update unless somehow the update gets interrupted such as a loss of power, or early removal of the flash drive.
Installed a replacement main board and immediately got the green/amber flashing pilot light. Unfortunately after numerous attempts I cannot get the update to start. Tried everything in your video including downloading the software to a different flash drive, nothing works. The backlights come on with some power up attempts but not every time. I also have sound and the optical output is red so the board is getting some power. I tried disconnecting the lvds ribbons one at a time and then both at the same time but it didn't make any difference, the tv behaved the same way. I'm at a loss on what to do next. Any advice would be appreciated.
Hi Nick. I've replaced my main board on my 49xf9005 and when I turn it on for the first time, the white light comes on and after a while the screen flashes up a black and dark grey checkerboard then goes black and repeats the checkerboard. Is my replacement main board faulty? Thanks.
It does sound like you could have gotten a bad mainboard indeed. I would recommend first reseating your ribbons and try again, but if the same issue persists then yes I would say get a different mainboard.
Hi nick I'm. In the uk, my sony W905 46" TV has started flashing four red lights. It won't switch on properly just knocks off onto the four red lights. Any help will be much appreciated. Thanks Steve
4 blinks is an indicator of LED failure. You will need to replace your backlight.
Do you have any suggestions or recommendations if there is no amber/green light at anytime? I've tested the power supply and main board with a voltage meter and compared to the manual, and it appears as they're both functioning, but no display, sound, lights, etc from the TV. The USB does show power (red LED) when plugged in and power is connected to the TV.
With the flash drive plugged in and renamed to upgrade_loader.pkg turn the TV on. Make sure the TV is fully on, so allow at least 15 -20 seconds after pressing the power button for the TV to turn on.
Once it is on, press and hold the power button on the back of the TV until the pilot light goes away. Once it does go ahead and release the button. This can take anywhere between 10 - 30 seconds. Wait another 10 -15 seconds and the set should turn itself back on and detect the flash drive. At this point the set should be taking the update. If it does not, repeat the procedure. If you still don't get the TV to take the update, the next step would be to have you remove the flash drive and power, disconnect the LVDS ribbons from the main board and power it back up. This should trigger the amber green light. Once it does, disconnect the TV from power, connect the LVDS ribbons back in, plug in the flash drive, and apply power. One of the above steps should take care of the issue.
I think I fubard my main. Anyway I tried to reflow the chip and warped the heck out of the board, too hot!!! I have a Yihua 853AAA, how hot would you set the pre-heat and the air gun? So at this point I either buy a new main, and risk maybe the panel is bad, (likely) or buy a panel tester, test the pane,l but at least I have the tester to show for my money. If the panel test bad. I could buy a new main if ok. I did get it paired and had a pic, although it had lines and dark areas, so the main prob was ok I'm afraid.
If you have a Sony TV I don't ever recommend trying a reflow. 2015 and newer Sony sets never fail due to cracked solder joints. It's always a part that needs to be replaced.
The heat profile is not what causes warping, uneven heat to the board is what causes it. You have to heat the entire board at the same rate, if you don't then you get warping.
By default, you will always have a little warping because different materials have different thermal expansion coefficients, but you can reduce that warping by doing more even heat to the board.
@@NicksTVRepair I'll have to practice on some junk boards. I got the bottom too hot, smoke alarm functions fine. Then knowing what chip needs replaced is another guess, I priced some, like 12 bucks on Ebay, not bad. BTW do you have an Ebay store, I saw one in Tucson. Reworksrus
ahh same problem just ending software update shows logo SONY the light blue and starts again updating any advice or may i exchange the main board ? ive done 5 times and by itself like 10 times finalized intalation shows sony logo then starts again
Oh okay, so the update you did previously only ended up making the set work for a short period of time then.
Looks like you will need to either replace the main board or have it repaired. It seems the defect on it is bad enough that a software update is not going to be enough to resolve the issue.
If you are in the USA, we can service the main board for you. If you are or have a TV from a different country, then you will need to find a service within that country.
Let us know if you have any additional questions.
what about a sony bravia kd A1 with 8 times red blinking. updating the TV via usb is working sometimes (1out of 10 attemps), but as soon as i shut down the tv for 5 min, the red led starts again to blink 8 times. wenn i shut down the tv for just 10 sek. the tv starts and all works fine.
Since I don't know what model you are referring to I am going to assume it is similar to the XBR55A1E model.
8 blink code means 4KBE Error (4KBE WDT)

Hey Nick's repair I have a sony xbr65x900e that turns on for about 10 -15 seconds and then shuts off with 4 blinking red lights. All the leds are good, I took it apart and tested them all so what would u think my problem is? Thanks
Hello Richard,
A 4 blink error code is an error code due to defective LED's. I uderstand you tested them and they tested good, however most testing equipment is not sensitive enough to detect failed LED's unless they completely failed open or shorted.
The best course of action at this point since the LED's aren't fully failed would be to bypass the error by shorting out the
BL-ERROR pin to ground. This will prevent the set to go into a 4 blink code. This is not a "correct" repair, but will not negatively affect the TV. Once the LED's fully fail, then you will start to see dark spots on screen wihtout triggering the failure and will at least still be able to use the TV.
If you aren't sure how to ground the BL-ERROR pin, please let us know and we can try to explain it better.
@@NicksTVRepair yes how do i ground the back light error pin thanks

Please keep in mind it's not a legit repair, but sometimes allows the set to keep working for an extra couple of years since that error sometimes is triggered even if there isn't an actual issue.
@@NicksTVRepair model in question is a xbr 55ae8, before seeing your comment I had tried this, both removing the bl_err wire and leaving it open, grounding the bl_error wire to the chassis, a ground on the power board, and a ground in the harness itself. in all situations we get no picture and 4 flashing red lights. on this model I believe the backlight is non serviceable. thanks for your reply!
Hi, Nick have question I have the 12v and 3.5v on main board can make the white light on tv turn on still no picture can’t seem to make it update. And there is no 12v at the fuse on t-con board what could cause no 12v to t-could board?
This is a mainboard fault. The voltage only shows up if the mainboard tells the power supply to turn on and provide that voltage.
@@NicksTVRepair Thanks for getting back to me I’ve tried 3 different main boards same results is it possible to get that many bad main boards?
Hola gracias x la información hice todo lo que sugiere el vídeo y sigue arrancando con luz verde ámbar..
Estube midiendo y no tengo las señales on en la parte de backlight ni en la q alimenta la t com ..
Pero si reacciona al poder y se escucha una música pero como dije sin iluminación y sin voltaje en la t com ..me podrías recomendar como seguir. gracias
Hola,
Lo más probable es que el problema sea que las cintas no están conectadas correctamente o están dañadas. Si tiene una placa base de reemplazo que compró usada, entonces también es posible que tenga un conector dañado en su interior que le impida conectar correctamente sus cintas también. Vemos esto todo el tiempo. Así que revise sus cintas, asegúrese de que estén al 100% y no estén dañadas, también asegúrese de que su reemplazo no tenga residuos dentro del conector.
Gracias x responder tengo una duda ..mientras enciendo el tele o se carga el firmware en la t com no tengo alimentación (12v) esto es correcto ..? Probé los Flex y están bien..
Este problema me pasó cuando reemplace las tiras led no la Main ..lo q hice fue encender el tele para ver si prendían los LED sin la pantalla tampoco estaba conectada la y com ..los LED se encendieron luego se apagó y quedó así parpadeando naranja verde ..luego coloque la pantalla conecte la t com pero nada ..te quería comentar el problema si hay alguna otra cosa q me puedas ayudar ..
Thankyou so much Nick for your tutorial . I completed the pairing process with great results. The tv now powers up and i get the welcome screen. Unfortunatley i have horizontal pin stripe lines at on the lower bottom of screen and also ghosting/flashing. Could this be a damaged T-Con board and should i purchase a replacement. I have already replaced the ribbon cables but still problem exists.
Your advice is greatly appreciated.
Thankyou in advance
Dave
Dave,
It sounds like you may have a panel failure. The true fix would be to replace the screen, however that is not a financially feasible option as it would cost more to fix the TV as it would buying a new one. However there are tricks that can be done to still fix the issue without a full replacement. This maybe something you can do on your end at home without needing expensive equipment or tools.
For more details on this, please send us a message to our support@nickstvs.com email with the full model number of your TV, a picture of the screen, and a description of the situation. We may be able to assist from there.
I know I am kind of off topic but does anybody know of a good website to stream newly released movies online ?
@Scott Vincent flixportal :P
@David Ryder thank you, I signed up and it seems like they got a lot of movies there :) I appreciate it!
@Scott Vincent Glad I could help =)
Hi Nick. Great video but I can't get my light to light up at all. I have replaced the power board and then tried putting the usb and renamed the file into the main board but nothing. Any ideas? Thanks in advance from the UK
your mainboard must be defective in a more serious way then. An update may not be enough and you may need to send in the board for repair, and or replace it then. A good amount of the mainboards we receive for repair, come in completely dead, and that's when we have to replace some of the hardware to get them working again.
@@NicksTVRepair Thanks Nick for your advice, makes sense. Our local TV repair place is shut at the moment. I have found a board with the same model number 1-894-595-12 which is off the 55'' tv. Do you know if they are interchangeable?
Sorry for the delay in my response. The answer is that it would depend. What model TV do you have and model TV does the board you found go to?
Hi Nick, i had a XBR-55X700D and i replace the T-Conn board, i try all the steps in the video but i can't get the pairing mode, do u have some help?
Never Mid, you are the best boy!
Sometimes you can do everything correctly, and still have issues. I always recommend to try at least 3 times before going to the next step.
Hey nick's repair how do u ground the blacklight error pin on my sony xbr65x900e. Thanks!
We have never had to do that for the 900E models before, but I would suggest you simply don't plug in the ribbon that connects the main board to the LED driver board. Fully remove it entirely from both plugs and try to power up the set. This will cause an auto on for the backlight but also will make you loose contrast quality of lighting by doing so as it will be stuck on full brightness for every scene no matter what.
Now if that doesn't work and the backlight still doesn't stay on, then you simply will have to replace the LED strips. Those strips are available for sale at Shopjimmy.com. They have 2 versions, so double check which one you have before buying

@@NicksTVRepair tried the ribbon removal and it doesn't even show a picture. The led turns on right away when plugged in then shuts off. Then I try to turn it on I get the white light for a sec then 4 blinking red lights. Now I have a led tester and I tested the strips and all worked and turned on. Do u still think it's a led issue?
Is there a different name to rename the .pkg fir H series. I put a new t-con into a 75z8h and got red/white alternating instead of amber/green. Other sites say that means it needs update. Won't take with Sony's file after extraction. Won't take after renaming it to upgrade_loader.pkg either. Any ideas?
This only works with the C-D-E-F models per the video title. The G-H and any newer models you will NOT want to rename the file. It will not work.
Red white does mean it needs to be paired/updated.
For the G and H models you will need to download the file, extract it only once, and then put that file on the flashdrive as is.
Then plug it into the TV and then plug the TV to power.
It should take.
@@NicksTVRepair I know that's typical procedure as I've done it before, but it doesn't seem to want to take
I am at the point of where I am doing the 6 to 8 hour thing. I started about 6 PM and an hour later the light turned yellow. About 15 minutes after that the light turned red and is still solid red at about 8:30 PM. I am planning on leaving it run like that for another 5 hours. But I do not know what I should do after that .
Martin,
What model TV do you have? This video covers a few dozen models accross about 4 years of Sony TVs.
The red light you are seeing generally is an indication of some sort of error, but can also be normal if your have the 2017 model which end with the letter E.
@@NicksTVRepair XBR55X800E. At 10PM I hit the power button and it turned white and started flashing, At 10.20 I checked and the screen was lit. I left it on overnight. Still have a lit screen and a steady white light. I had replaced the LVDS cable before I started the update and put the old one back in, Hit the power button and the pix was back and I now have the customers set working. It must have updated overnight with the bad cable. Thanks for everything.
Hi Nick, i have a xbr65x850d that the original main board is stuck in boot loop. I received two replacement main boards. When installed i get white/green flashing light but no backlight or picture, is this because of pairing? I get picture and backlight with my old board but not with replacements.
Willie,
Yes that is correct, you will need to pair your board in order for it to work with your TV set. Unfortunately this is not a plug and play situation. Once the board is paired however there is a chance the original board will no longer work with the TV set as it will have paired itself with the new boards you installed. You can reverse it and pair the original back again if you would like however.
@@NicksTVRepair Thanks, I will try again when I have more time. If it doesn't work then I will have a 65" paperweight!
@@willieoutlaw4957 For your situation you had mentioned an android man appears on screen. That android guy/logo will stay on screen for up to 30 minutes or an hour. It may appear as if it is stuck/ frozen, but it is simply updating. If you unplug or remove power during the updating process, you may damage the board. I recommend you let it sit/update for over an hour just to be sure. If the android guy is still on screen for more than 1 hour, then you may in fact have an issue with the update/pairing properly installing and may in fact have a circuit board with bad software.
These sets do require a lot of patience. A lot more than any other brand.
@@NicksTVRepair I've been repairing sets for years and this is the first time I came across this, thanks Nick
My X800E does start the white glowing LED and it said on the TV that it's updating. The update process goes only halfway and it stopped. The screen goes out with the blue LED shown before it goes back to Sony logo and stuck there.
Any suggestions would be great.
Thanks.
Based on the information, it seems you might have an issue with the main board that is more severe and will need a part replacement. I would suggest trying the update at least 3 times, but if it still has issues after the third time, it is likely you will need to either purchase a new replacement board, or have your original board serviced if new replacements are not available.
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 this?
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
Nick, during the pairing process I am receiving a solid red light after 5-10 minutes of the amber green flashing. What does this mean?
Does the red light blink or stay solid red? If the red light is blinking, how many blinks?
Which model number is this for?
Nick's TV Repair Nick, I am not sure what happened. I unplugged the tv from the power source and tried again. After about 15 minutes of amber-green flashing the tv turned off. When I turned it back on from the remote the white flash began and the update process was completed about 15-20 minutes later. Everything appears to be working as new again. Thank you for all of your help.
Just for future owners I had to try 10-12 times to get the pairing process to begin with my USB stick, I did not change the name of the update loader as i did not have my PC with me. This may have been what took it so long to work.
Maybe will u have the firmware of the XBR 55x850D? the system doesnt exist on sony website :(
So recently Sony did take down the software for the flash drive. We had luckily saved a version of it.
When we heard they took it down we uploaded it on the Megaupload website which is a file-sharing service we are paying a monthly fee to share this software. We are not charging for it, you can download it for free here now:

Hi..So i bought my Sony Bravia 32 smart tv and i updated the software but now my live channels cannot be found.The signal is OK 96%.. Can i delete the update?
That I am aware of there is no simple way to delete the update, you may be able to revert back to it if you are able to find an old version of it available online, place it on the flashdrive and forced the old update back onto the TV but this most likely will not resolve your issue. You can most likely find the channels again by preforming a channel scan. This will sometimes happen after a software update of if a factory reset is perfomed, the channels will be lost.
A simple channel scan should resolve the issue.
