I just finished up my install using your tutorial, and it worked like a charm, even for a novice tinkerer like me. Thank you very much! That said, I have a couple of observations pertaining to the LED-install portion for anyone attempting to do this: When removing the old strips, I noticed that they each had a pink rubber strip on the bottom, which I didn't hear you mention, and which was noticeably absent from the replacements that I had ordered. That said, I was able to remove them all with the smallest bit of force, and the adhesive remained sticky enough to reattach to my new strips. I'm not sure what purpose they serve, and lining them up can be a huge pain--especially when also trying to line up the strips--but I erred on the side of caution and reinstalled them anyway. Regarding the black foam that comes on the stock strips, I was able to remove them pretty easy. At first, I attempted to slide a thin razor blade under it, but after playing around with it, I found it much easier to just gently pull them off by hand--no tools needed. After that, it took some effort, but I was able to stick them to my new boards. There were a couple of spots that were no longer sticky, but it looks like it compresses against the screen anyway, so I just pressed them down the best that I could. The only problem area on the foam strip that I had was that about an inch of it on one end kept springing back up. So, I threw a very small strip of double sided tape under it and cut off the 2-3mm at the end that still wouldn't stay down. No light bleed on my end!
Wow that's awesome! Yes I did not talk about the pink silicon strip that is behind. Often those are used as a heat transfer however they don't make contact with anything from what I recall and thus it doesn't really make sense to me what it is there for. As for the black strip in front, that's lucky, typically they are so heats stressed in my experience that it just falls apart and you can't really reuse it. Glad you had a successful repair and were able to get it done without any light bleed.
I have an XBR 65X950G with 4 blinking red lights. Wish I had found your videos first as I tried the BL-ERR pin removal and ground (no joy), power board changeout (no joy) and some other things. Problem is not solved. Could not locate the repair manual. Was thinking now maybe T-CON board until I saw your videos. I do wish you had a video showing how to change the LED strips on this model. I know that others have asked about it as well. This is a fairly new model (2019 on board) and I think I bought it in 2020. I used to praise Sony products as I had older Sony TVs and other products that lasted forever. A little over 2 years on a high end TV IS NOT RIGHT! Please, make a video with an XBR 65X950G!
I am very happy you were able to follow along. We sped up a few parts so it must have been a bit tough to follow along 100% of it but I am glad it helped and that you got your TV working again!
Of all the videos on you tube this is the best one! Most of the other ones there's too much detail, makes me feel like I'm in grammer school! Not good job Nick, the best job!
Hey Alex! Glad to hear you jumped onboard! No the light bleed is not normal. I am still working on a solution to fix that but that I am aware no one has really come up with a really good solution. If you rewatch the end of the video I explain why this happens.
I was doing a led light strip replacement and all went well thanks to your video, But I powered the Tv on without having the top left white plug with gray wires on main board pluged in.

Hey Nick, question regarding this same TV. Btw I been watching your videos your the man beautiful way of explaining everything every time brotha. So same TV picture is clear and clean but I’m staring to see yellow bleeding through the bottom portion of my screen just like at the end of your video how you have led bleeding out but mine is yellowish bleeding what do you think that means? Is it maybe time to replace led strips ? btw have you found the black form strip yet ?
I have not yet found a good solution. Part of the reason is that I have actually only had a couple more of these TVs come into the shop since this video, 1 of which didn't have any light bleed at all and so there was nothing for us to try and the other was on the opposite end of the spectrum, it was one of the worst we had ever seen and everything we tried didn't really have much of an effect. I think what causes this more than anything is the fact that the LEDs are getting so hot that they melt the diffuser plastic and that's probably what causes it. Meaning there really is nothing you can do about it. You can preventatively lower the backlight setting but once it's there I don't think there is anything you can do to make it go away.
I'll need to get the part "if"... Would you say that XBR-65X850D and the 900C are similar? Great Video by the way, lot of work. I appreciate you in advance.
The 4 and or 6 blink code which is the LED failure both occur on these models so they are similar in that regards. As for the removal and replacement process they are very different.
Sorry, you and several other people have requested this video. I don't have it but I am keeping an eye out for this model. The next time it comes into my shop for an LED repair I will make sure to film it. For now, I don't have one. For now, I recommend you watch the video linked below. This is not your TV, so it won't be the exact same, but it is for a similar Sony and will help you get an idea of how to do this: ua-cam.com/video/kbk2SJkmtnM/v-deo.html&t
Thank you for the tutorial! I was able to replace the LED-Strips thanks to your Video🙌 One thing did not work perfectly however 😅 The backlight is much brighter at the buttom now than on the rest of the screen… The LED-Strips fit perfectly (at least it felt like they don’t move…) Did you have the same problem after some replacements?
The most fragile part of the TV, the COFs (chip on film), the ones from the display to the timing/scallar/driver board on each side(this size 2 of them). These COFs are really fragile, please use some BBQ sticks or some other stuff with a masking tape, or a capton tape from the other side. You'll make it flat and won't allow for them to bent down as shown at 6-7 minute in the video. That will make it safer. Thank me later.
Not really sure I understand what you are saying when you state "please use some BBQ sticks or some other stuff with a masking tape, or a capton tape from the other side"
@@NicksTVRepair These are looking like a big long match as just a wooden stick and sharp at both ends to stick your meat and veggies on it and make a shashlik. I glue with a capton tape to the display/screen and COFs lying on it. Otherwise, these were falling and was quite risky for me.
HI NICK. I HAVE A SONY XBR-55X900C. I DONT HAVE A PROBLEM WITH THE LEDS, BUT I HAVE SMALL VERTICLE RED LINE FROM TOP TO BOTTOM.IN THE MIDDLE OF THE SCREEN. MY QUESTION IS THAT A PROBLEM WITH THE SCREEN OR COULD IT BE WITH THE CABLES GOING TO THE SCREEN . JUST THOUGHT YOU MAY HAVE COME ACROSS THIS PROBLEM AND YOU MIGHT HAVE THE ANSWER. THANKS SO MUCH. KEEP UP THE GRATE WORK .EXCELLENT VIDEO. VICTOR
Victor, Well it shouldn't hurt to simply reseat the ribbons, but in my experience that is an issue with the screen itself. The only way to fix it would be to replace the screen.
I have links to the LED strips for sale in the video description. You have to check the description. If you are on mobile or using a tablet, YT has made it more difficult to see it. It's almost hidden now but I assure you it is there.
Hi Nick, my problem on my tv when I turn it on the screen goes like android is rebooting or updating just like in your video but the led lights don't blink, just it turn the tv off and the led on the bottom of the tv blink in red clor 4 times, I would appreciate if you tell me the possible problem by your experience please. Thank you very much, your videos are very, very helpful. Jorge
Hello, What you are describing is still an LED failure, it just has a slightly different symptom than what we are experiencing in this video. There are a few different ways the LEDs will fail and depending on how they fail, they will display slightly different symptoms. Sometimes it triggers a 4-blink code and sometimes it triggers a 6-blink code but either way, it does require new LED strips to be installed to repair this unit. If you are interested in doing the repair yourself, we do have these for sale on our website. There is a link to the strips in the video description.
@NicksTVRepair thank you very much for the info, I will think about replacind them, I am not gifted like you thou, but I will consider it as a hooby to change them. I will go to your wensite to buy them. You are great. Have a great day.
Hello Nick, a while ago I asked you about the led stripes for my tv and you told me that you sells them, can you let me know or send me the link where I can buy the led thank you. Have a great day
Hey Nick! I have a 65x90k with 4 blinks. It'll come on and dispkay the sony logo then the google logo but then shuts off and blinks 4 times. Ive tried grounding the BL_err pin but nothing changed. If I unhook both lvds cables then itll go into the color cycle screens and not turn off. If I leave the top lvds cable connected, itll do the color cycle again, but if i connect the lower and disconnect the upper lvds cable then it goes back to the 4 blinks. Any guesses as to the cause?
4 blinks are #1 caused by defective LED strips. To fix this you need to replace your LED strips as done in this video. There is a very small amount of TV sets that sometimes can trigger a 4-blink code not because of defective LEDs but instead because of a defective driver board. I do not believe yours is one of those which means you need to replace the LED strips to fix your TV. I don't have these for sale, but the best company to buy replacement LED strips from which is the company we use as well is Shopjimmy which I will link below. www.shopjimmy.com/sony-1-013-011-11-led-backlight-strips-20-xr-65x90k/
@@NicksTVRepairThanks. I figured it would be backlights but wasn't sure since grounding the BL_err pin didn't bypass the turn off. Wasn't sure if that would indicate a defect in the panel itself. I swapped the driver board with a working one in the past, just to test, but that didnt solve it, so pretty sure that's working
Helpful video. Have a 75xbr750e. Led problem. Replaced them but having a problem putting the plastic trim back on . Don't remember if the screen is separated from the other panel by the plastic trim. Any help. Thanks.
I would recommend browsing for a video on that one. It's a different type of set than this one. I don't know that I can help you without seeing exactly which step of the process you are on. Shopjimmy.com has lots of videos on youtube for backlight installation, they may be better able to assist you.
Good afternoon, could you help me? I have this TV, but I've never been able to enable the Sony logo to appear as soon as I turn it on. Could you tell me how I can do it? You seem to me to have a good understanding of these TVs. Thanks.
"I've never been able to enable the Sony logo to appear" A quick google search brought me to the sony support site and reads the following: "Go to Settings For models released in 2019 or later: use the Quick Settings button On the remote control, press the (Quick Settings) button. Select (Settings). For other models: use the HOME button On the remote control, press the HOME button. Select (Settings). The next steps will depend on your TV menu options: Select Channels & Inputs → Info banner → set to disable Select Watching TV → Info banner → Hidden or set to disable Select Channels → Info banner → Hidden or Off Select Channel setup → Info banner → Off or set to disable"
hi Nick,I have sony xbr-55x900C on startup android logo comes on and TV shuts and the red blinks 4 times. So it that a mother board problem as mentioned in of your videos or is it LED Strips which need to be replaced. Any help will appreciated.Thanks
That's something you will have to find out on your own. Look up on google your model + LED strips, and find a vendor. They will have their own prices and shipping fee. eBay probably has lots of sellers for these.
Hi Nick! I changed the LED strips on my XBR65900C but it's still somewhat dim. Took it apart a second time to make sure the LEDs were lined up correctly it I believe they are. Have you run into any other issues that would keep it dimmer?
I have not. Perhaps something in the settings? How dim is it? To the point the set is not watchable? If so it's possible the alignment is not right. Are you using the LEDs we are selling or ones from another retailer?
@NicksTVRepair the set is watchable. As an example, it went from around 50 nits full screen to about 100. I know this tv was about 200 nits full brightness before the LEDs started burning out. Unfortunately, I purchased these LEDs from an Ebay vendor before I found your video. Looking at the strips, they were same height and numbers, so I don't think they're my problem.
Hello, I have a Sony Bravia 65-FX9005 TV, on which I installed all the components from another TV identical to the broken screen, but it does not update or factory reset, instead the LEDs light up and there is a sound song in the background. I understood that, unfortunately, the motherboard must be resoftened for the new screen. What do you think?
If the picture is not appearing it's most likely because the ribbons are not properly inserted. This is the most common reason you don't get picture after replacing a mainboard or swaping out the T-con. Reseat your ribbons, that should do the trick.
Hi - just saw this. I have a xbr65x930d with a vertical lines on screen issue since late last year. The vertical lines are the only video that appears on the screen (no picture other than the lines). I just ran across your channel on the light repair. Your videos seem to be some of the best around for this tv. Is there a way to upload a picture of the screen so that you might better understand the problem with my tv? My user picture shows the issue (but I realize it's probably really too small to see correctly).
When it comes to lines usually the fault is screen related and not repairable. If you want to email us a picture I can confirm this for you. Our email is in the video description.
Yes based on the picture you provided I do believe you have a bad panel. But the tape they use is just called black out tape. You should be able to find some online.
If you are talking about the smaller brown power supply board, it's just called a sub power supply board, but I do blieve it is to power the LED driver board so in a sense you could say it is part of the driver.
Hi Nick. I have an XR-55A80J OLED with a vertical white line on the screen since one month ago, despite this, there were no problems with the TV image. A week ago the TV stopped working and 4 red blinks appeared. Do you know how I could fix this? Is there something that needs to be replaced?
That I am aware of there is no way to fix this issue when it occurs with an OLED TV. I would recommend looking into any possible warranty claims. Was there an extended warranty purchased with the TV? Do you have home onwers inssurance? Sometimes TVs are covered under home owners inssurance. Perhaps you purchased the set with a credit card that provides an extended warranty?
Hi, have a issue with 55A80K 5 red blinks, black screen, if disconnect tcon motherboard stays on, try to replace tcon no luck same thing 5 flashes, any suggestions would be much appreciated, thank you
I would recommend you get a second opinion but this sounds like a defective panel to me. A defective panel means the screen is bad, which is not something that can be fixed.
I’m looking for some good backlights for this as I’ve tried some and they used the wrong leds which was at the wrong height, I see you sell them but are the leds that are not same as original and are Samsung leds ? My opinion is the leds are the wrong height and too close to each other as well
If you watch the video until the end, I go over some of the information as to why I believe there is light bleed still post repair. There are no manufacturing company that I am aware of that will sell LED strips that are 100% going to work with 0 light bleed. All of them have the light blocking strip missing. But the main reason why I think no matter what there will always be some light bleed is because humans are replacing these LED strips not machines. Humans make mistakes and are not as precise as a machine. These things have to be done 100% perfectly in order to have 0 light bleed. The #2 reason is that these TV sets even when assembled brand new by a machine still had a percentage of the TV set owners complain about light bleed. Now throw in that the replacement LEDs don't have the proper light blocking strip that should be there, and here we are.
@@NicksTVRepair yh I did comment before I watched the end but I don’t think the issue is the black foam strip, it’s pretty obvious the leds used are completely the wrong height so that will cause issues in a slim tv like that, the leds used in the replacement strips are completely the wrong ones, wrong height and these are very close to each other basically touching each other, the original ones have a gap between each led but the main issue is the height of the leds, you may disagree but that’s what I think
Hey I have a XBR-65X900C it was working just fine the other day, but now whenever I turn it on the screen turns on and off over and over . Any idea on what may be wrong with it?
Hello Jesus, Yes that is in fact very common and is one of the failures we deal with the most. I have a video on how to fix it but long story short you have a mainboard failure. Check out our video here for more info. ua-cam.com/video/gxJtLqeBcBA/v-deo.html We also fix these mainboards for that failure at a flat rate fee and a 1 Year warranty. For more information contact us directly. Our email is in every video description and or you can go directly to our nicks electronics repair website and fill out our contact form there as well with any questions.
So I didn't mention it but one of the issues is also that you stretch out the original and it sometimes falls apart depending on how much heatstress it went through. So it does loose some of it's thickness and shape. But I think one of the issues I realized is that the diffuser sheet actually melts a little on some sets and that also in part has something to do with it.
I had several bottom lit Samsung that melts the diffuser as well. I repair hundreds of led failure an year. I do mod the LED driver circuits to lower the current.
Hello can you give me a hand? I have a Sony kd-65x9005c which had a 4 blink error. I ordered the LEDs which I replaced but unfortunately after reassembling the whole TV I only have sound and no backlight or video. I tried reinstalling a new firmware but still nothing.
Yes the XBR-75X950H has the same blinking code system. 4 blinks means your LED strips need to be replaced. Although for your set it's a bit more difficult than the one I do in this video.
I saw a similar video to change the leds but now when turning on it starts flashing green - orange and after a while it sends audio but the leds never turn on
Yes when that happens it's because either the ribbons connecting the mainboard to the T-con are not connected properly either on the mainboard side or the T-con side, the ribbons between the T-con and screen are not connected properly either on the T-con or screen side. You need to reconnect those and make sure they have good contact. Once you do that it won't fix it, now you have to pair the mainboard back to the screen. I have another video on how to do that for a different Sony TV, but the process is identical: ua-cam.com/video/gBd2g7kRsEM/v-deo.html
Please let me know where I can buy the original strips. Ali baba and ebay have them but which is more reliable. Any other place to buy, I am in Pakistan such items not available here.
Has anyone been able to fix the light bleed at the bottom of the screen???? I put on the black strip of foam that originally was on the original LEDs - but I still get light bleed, any suggestions?
Cut this adhesive thingy off this old one and use double sided tape or something else on the new one. I bought a high temp double sided tape for many things in the TVs where it's too hot and works fine.
The adhesive on the LED strips? are you saying to peel it off and put it on the new strip? It's not really possible, it starts falling apart into pieces due to the heatsress. It almost gets brittle. Maybe yours had a lot less heatstress was in better condition?
@@NicksTVRepair yes, wasn't nice as well to be true, was time consuming. But, without it, or other replacement, you will have this light which is even worst and customers when see worst, some don't like to pick up the TV even. Had it a number of times in the past.
Hello Nelly 4 and 6 blinks are both caused by faulty LED strips Replacing your LED strips will resolve your issue. We do have the strips still available for sale on our website if you are interested, just check out the links in the video description.

Guys please help! i have sony bravia Model : "KD-65X9004A" The Tv turns on dimmed like the image is on 50% but its full on brightness.. after a minute it slowly turns off and the Indicator Flashes Red 4x times... what could be the problem ? i can't find any solution regatding this model on the internet also no tutorial or parts for backlight.... any solution?
Sorry we don't work with that model but you do indeed have a bad backlight. 4 blinks means you need to replace your LED strips, we can't help you with that but a local shop might be able to
Hello bro I have the same problem like this on my Sony KD65XE9005. Is this method compatible with my model or what should I do? It’s exactly the same problem. Thanks
That will be the same exact problem, but your TV might be a little different and may use slightly different LED strips but the concept will be the same.
The hand held camera used for most of the footage is the one we got from like a year maybe year and a half ago or so, the second one we used was an old camera, actualy it's the camera we used for the very first videos we made from like 3 years ago.

I noticed that the original LED strips were 88 LED strips, whereas the new ones seem to be 64 LED strips. Is that the case? I am planning to replace my strips but my TV has 88 LED strips and I cannot find those.
Will, Yes that is correct the replacement strips have 64 LEDs vs the originals are 88. I don't know why that is, but there are no manufacturers that remake them with 88 LED's which I don't know why that is the case.
@@NicksTVRepair I finally got around to replacing the LED strips on my TV. After replacing the LEDs the TV still has this weird flickering at different spots of the screen. Like the LEDs turn on and off. I can get those spots to go away if I turn the brightness all the way down to low. Could it be that the LED driver board is malfunctioning? I am not sure if you've had a case like mine. Any help is appreciated.
Sir I have sony model kd65x9300d problem is screen ok watching video after 1 minutes it go for 4 time blinking mode please help me to find the solution
Hi nick have Sony 55w905a like 8 years now whene open power on see channel and sound play can go and menu and after 30 sec close and blink 4 red what problem think have?
So the more I look into this the more I am finding out it doesn't have to do with the replacement LEDs but the plastic diffuser gets burned up and melted. It seems these replacement LEDs work well with some sets and not as well with others, and the difference seems to be if the plastic diffuser is damaged from the original LEDs going out. Sometimes they don't damage the diffuser sometimes they do and melt it a bit which causes the light bleed.
I have another one of these same sets that just walked in the shop again with 6 blinks. Ill give that a shot and record it. Hopefully that does it. Thank you!
I just finished up my install using your tutorial, and it worked like a charm, even for a novice tinkerer like me. Thank you very much!
That said, I have a couple of observations pertaining to the LED-install portion for anyone attempting to do this:
When removing the old strips, I noticed that they each had a pink rubber strip on the bottom, which I didn't hear you mention, and which was noticeably absent from the replacements that I had ordered.

I'm not sure what purpose they serve, and lining them up can be a huge pain--especially when also trying to line up the strips--but I erred on the side of caution and reinstalled them anyway.

After that, it took some effort, but I was able to stick them to my new boards. There were a couple of spots that were no longer sticky, but it looks like it compresses against the screen anyway, so I just pressed them down the best that I could. The only problem area on the foam strip that I had was that about an inch of it on one end kept springing back up. So, I threw a very small strip of double sided tape under it and cut off the 2-3mm at the end that still wouldn't stay down.
No light bleed on my end!

One thing did not work perfectly however 😅
The backlight is much brighter at the buttom now than on the rest of the screen… The LED-Strips fit perfectly (at least it felt like they don’t move…)
Did you have the same problem after some replacements?
Hello,
Yes Unfortunately you will typically get a bit of light bleed. I don't know if there is a way to fix that.
The most fragile part of the TV, the COFs (chip on film), the ones from the display to the timing/scallar/driver board on each side(this size 2 of them). These COFs are really fragile, please use some BBQ sticks or some other stuff with a masking tape, or a capton tape from the other side. You'll make it flat and won't allow for them to bent down as shown at 6-7 minute in the video. That will make it safer. Thank me later.
Not really sure I understand what you are saying when you state "please use some BBQ sticks or some other stuff with a masking tape, or a capton tape from the other side"
@@NicksTVRepair These are looking like a big long match as just a wooden stick and sharp at both ends to stick your meat and veggies on it and make a shashlik. I glue with a capton tape to the display/screen and COFs lying on it. Otherwise, these were falling and was quite risky for me.
Awesome skill and steady hands..
Thank you
HI NICK. I HAVE A SONY XBR-55X900C. I DONT HAVE A PROBLEM WITH THE LEDS, BUT I HAVE SMALL VERTICLE RED LINE FROM TOP TO BOTTOM.IN THE MIDDLE OF THE SCREEN. MY QUESTION IS THAT A PROBLEM WITH THE SCREEN OR COULD IT BE WITH THE CABLES GOING TO THE SCREEN . JUST THOUGHT YOU MAY HAVE COME ACROSS THIS PROBLEM AND YOU MIGHT HAVE THE ANSWER. THANKS SO MUCH. KEEP UP THE GRATE WORK .EXCELLENT VIDEO. VICTOR
Victor,
Well it shouldn't hurt to simply reseat the ribbons, but in my experience that is an issue with the screen itself. The only way to fix it would be to replace the screen.
Would like to order the led lights. No description in your video
I have links to the LED strips for sale in the video description. You have to check the description. If you are on mobile or using a tablet, YT has made it more difficult to see it. It's almost hidden now but I assure you it is there.
Hi Nick, my problem on my tv when I turn it on the screen goes like android is rebooting or updating just like in your video but the led lights don't blink, just it turn the tv off and the led on the bottom of the tv blink in red clor 4 times, I would appreciate if you tell me the possible problem by your experience please.
Thank you very much, your videos are very, very helpful.
Jorge
Hello,
What you are describing is still an LED failure, it just has a slightly different symptom than what we are experiencing in this video. There are a few different ways the LEDs will fail and depending on how they fail, they will display slightly different symptoms.
Sometimes it triggers a 4-blink code and sometimes it triggers a 6-blink code but either way, it does require new LED strips to be installed to repair this unit.
If you are interested in doing the repair yourself, we do have these for sale on our website. There is a link to the strips in the video description.
@NicksTVRepair thank you very much for the info, I will think about replacind them, I am not gifted like you thou, but I will consider it as a hooby to change them.
I will go to your wensite to buy them.
You are great.
Have a great day.
Hello Nick, a while ago I asked you about the led stripes for my tv and you told me that you sells them, can you let me know or send me the link where I can buy the led thank you.
Have a great day
Really nice!!! There is a lot to do in this sony to install baclight!!! Nice work.☝👌☝
Oh yes backlight replacement is always very involved.
Hey Nick! I have a 65x90k with 4 blinks. It'll come on and dispkay the sony logo then the google logo but then shuts off and blinks 4 times. Ive tried grounding the BL_err pin but nothing changed. If I unhook both lvds cables then itll go into the color cycle screens and not turn off. If I leave the top lvds cable connected, itll do the color cycle again, but if i connect the lower and disconnect the upper lvds cable then it goes back to the 4 blinks. Any guesses as to the cause?
4 blinks are #1 caused by defective LED strips. To fix this you need to replace your LED strips as done in this video.
There is a very small amount of TV sets that sometimes can trigger a 4-blink code not because of defective LEDs but instead because of a defective driver board. I do not believe yours is one of those which means you need to replace the LED strips to fix your TV.
I don't have these for sale, but the best company to buy replacement LED strips from which is the company we use as well is Shopjimmy which I will link below.
www.shopjimmy.com/sony-1-013-011-11-led-backlight-strips-20-xr-65x90k/
@@NicksTVRepairThanks. I figured it would be backlights but wasn't sure since grounding the BL_err pin didn't bypass the turn off. Wasn't sure if that would indicate a defect in the panel itself. I swapped the driver board with a working one in the past, just to test, but that didnt solve it, so pretty sure that's working
Correct LED driver almost never fails.
the bypass won't work with your TV, it only works with the 900c models.
Helpful video. Have a 75xbr750e. Led problem. Replaced them but having a problem putting the plastic trim back on . Don't remember if the screen is separated from the other panel by the plastic trim. Any help. Thanks.
I would recommend browsing for a video on that one. It's a different type of set than this one. I don't know that I can help you without seeing exactly which step of the process you are on.
Shopjimmy.com has lots of videos on youtube for backlight installation, they may be better able to assist you.
@@NicksTVRepair Thanks.
Good afternoon, could you help me? I have this TV, but I've never been able to enable the Sony logo to appear as soon as I turn it on. Could you tell me how I can do it? You seem to me to have a good understanding of these TVs. Thanks.
"I've never been able to enable the Sony logo to appear"
A quick google search brought me to the sony support site and reads the following:
"Go to Settings
For models released in 2019 or later: use the Quick Settings button
On the remote control, press the (Quick Settings) button.
Select (Settings).
For other models: use the HOME button
On the remote control, press the HOME button.
Select (Settings).
The next steps will depend on your TV menu options:
Select Channels & Inputs → Info banner → set to disable
Select Watching TV → Info banner → Hidden or set to disable
Select Channels → Info banner → Hidden or Off
Select Channel setup → Info banner → Off or set to disable"
hi Nick,I have sony xbr-55x900C on startup android logo comes on and TV shuts and the red blinks 4 times. So it that a mother board problem as mentioned in of your videos or is it LED Strips which need to be replaced. Any help will appreciated.Thanks
4 blinks is LED strips
@@NicksTVRepair pls advise how much are led strips for sony xbr-55x900C plus shipping to florida
That's something you will have to find out on your own.
Look up on google your model + LED strips, and find a vendor. They will have their own prices and shipping fee. eBay probably has lots of sellers for these.
Hi Nick! I changed the LED strips on my XBR65900C but it's still somewhat dim. Took it apart a second time to make sure the LEDs were lined up correctly it I believe they are. Have you run into any other issues that would keep it dimmer?
I have not. Perhaps something in the settings? How dim is it? To the point the set is not watchable? If so it's possible the alignment is not right.
Are you using the LEDs we are selling or ones from another retailer?
@NicksTVRepair the set is watchable. As an example, it went from around 50 nits full screen to about 100. I know this tv was about 200 nits full brightness before the LEDs started burning out. Unfortunately, I purchased these LEDs from an Ebay vendor before I found your video. Looking at the strips, they were same height and numbers, so I don't think they're my problem.
Hello, I have a Sony Bravia 65-FX9005 TV, on which I installed all the components from another TV identical to the broken screen, but it does not update or factory reset, instead the LEDs light up and there is a sound song in the background. I understood that, unfortunately, the motherboard must be resoftened for the new screen. What do you think?
If the picture is not appearing it's most likely because the ribbons are not properly inserted. This is the most common reason you don't get picture after replacing a mainboard or swaping out the T-con.
Reseat your ribbons, that should do the trick.
Hi - just saw this. I have a xbr65x930d with a vertical lines on screen issue since late last year. The vertical lines are the only video that appears on the screen (no picture other than the lines). I just ran across your channel on the light repair. Your videos seem to be some of the best around for this tv. Is there a way to upload a picture of the screen so that you might better understand the problem with my tv? My user picture shows the issue (but I realize it's probably really too small to see correctly).
When it comes to lines usually the fault is screen related and not repairable. If you want to email us a picture I can confirm this for you. Our email is in the video description.
@@NicksTVRepair Thank you so much for the reply. I just sent you a picture of the problem.
What kind of tape do you rec to replace the stuff they use? This is the exact TV I'm working on, I need to fix it. It may have a bad panel.
Yes based on the picture you provided I do believe you have a bad panel. But the tape they use is just called black out tape. You should be able to find some online.
Hey BTW what is that board right above the Tcon? Led driver? why does it have R G B dots on the three cables?
If you are talking about the smaller brown power supply board, it's just called a sub power supply board, but I do blieve it is to power the LED driver board so in a sense you could say it is part of the driver.
Superb work
Thanks a lot 😊
Hi Nick. I have an XR-55A80J OLED with a vertical white line on the screen since one month ago, despite this, there were no problems with the TV image. A week ago the TV stopped working and 4 red blinks appeared. Do you know how I could fix this? Is there something that needs to be replaced?
That I am aware of there is no way to fix this issue when it occurs with an OLED TV. I would recommend looking into any possible warranty claims. Was there an extended warranty purchased with the TV? Do you have home onwers inssurance? Sometimes TVs are covered under home owners inssurance. Perhaps you purchased the set with a credit card that provides an extended warranty?
Hi, have a issue with 55A80K 5 red blinks, black screen, if disconnect tcon motherboard stays on, try to replace tcon no luck same thing 5 flashes, any suggestions would be much appreciated, thank you
I would recommend you get a second opinion but this sounds like a defective panel to me. A defective panel means the screen is bad, which is not something that can be fixed.
Thank you (
You are welcome and also sorry for the bad news
I’m looking for some good backlights for this as I’ve tried some and they used the wrong leds which was at the wrong height, I see you sell them but are the leds that are not same as original and are Samsung leds ?
My opinion is the leds are the wrong height and too close to each other as well
If you watch the video until the end, I go over some of the information as to why I believe there is light bleed still post repair.
There are no manufacturing company that I am aware of that will sell LED strips that are 100% going to work with 0 light bleed. All of them have the light blocking strip missing.
But the main reason why I think no matter what there will always be some light bleed is because humans are replacing these LED strips not machines. Humans make mistakes and are not as precise as a machine. These things have to be done 100% perfectly in order to have 0 light bleed.
The #2 reason is that these TV sets even when assembled brand new by a machine still had a percentage of the TV set owners complain about light bleed.
Now throw in that the replacement LEDs don't have the proper light blocking strip that should be there, and here we are.
@@NicksTVRepair yh I did comment before I watched the end but I don’t think the issue is the black foam strip, it’s pretty obvious the leds used are completely the wrong height so that will cause issues in a slim tv like that, the leds used in the replacement strips are completely the wrong ones, wrong height and these are very close to each other basically touching each other, the original ones have a gap between each led but the main issue is the height of the leds, you may disagree but that’s what I think
3:23 removing the t-con board, I am so lost on how to remove the clip. Not sure what side to push down or press in. 😖
Got it lol
Good to hear you got it figured out. For anyone else with the same question, you have to flip the black latch upwards.
Hey I have a XBR-65X900C it was working just fine the other day, but now whenever I turn it on the screen turns on and off over and over . Any idea on what may be wrong with it?
Hello Jesus,
Yes that is in fact very common and is one of the failures we deal with the most. I have a video on how to fix it but long story short you have a mainboard failure.
Check out our video here for more info.
ua-cam.com/video/gxJtLqeBcBA/v-deo.html
We also fix these mainboards for that failure at a flat rate fee and a 1 Year warranty. For more information contact us directly. Our email is in every video description and or you can go directly to our nicks electronics repair website and fill out our contact form there as well with any questions.
Could you use led tape to reattach the foam strips.
So I didn't mention it but one of the issues is also that you stretch out the original and it sometimes falls apart depending on how much heatstress it went through. So it does loose some of it's thickness and shape. But I think one of the issues I realized is that the diffuser sheet actually melts a little on some sets and that also in part has something to do with it.
I had several bottom lit Samsung that melts the diffuser as well. I repair hundreds of led failure an year. I do mod the LED driver circuits to lower the current.
Hello can you give me a hand? I have a Sony kd-65x9005c which had a 4 blink error. I ordered the LEDs which I replaced but unfortunately after reassembling the whole TV I only have sound and no backlight or video. I tried reinstalling a new firmware but still nothing.
Most likely the ribbons aren't connected in properly. Recheck all your ribbons.
Would this be similar to xbr-75x950h? I’m getting 4 blinking red lights
Yes the XBR-75X950H has the same blinking code system. 4 blinks means your LED strips need to be replaced. Although for your set it's a bit more difficult than the one I do in this video.
I saw a similar video to change the leds but now when turning on it starts flashing green - orange and after a while it sends audio but the leds never turn on
Yes when that happens it's because either the ribbons connecting the mainboard to the T-con are not connected properly either on the mainboard side or the T-con side, the ribbons between the T-con and screen are not connected properly either on the T-con or screen side.
You need to reconnect those and make sure they have good contact. Once you do that it won't fix it, now you have to pair the mainboard back to the screen. I have another video on how to do that for a different Sony TV, but the process is identical:
ua-cam.com/video/gBd2g7kRsEM/v-deo.html
Please let me know where I can buy the original strips. Ali baba and ebay have them but which is more reliable. Any other place to buy, I am in Pakistan such items not available here.
We have them for sale on our website. Links are in the description
Has anyone been able to fix the light bleed at the bottom of the screen???? I put on the black strip of foam that originally was on the original LEDs - but I still get light bleed, any suggestions?
The more I talk to people the more it seems like it's random and some TVs get no light bleed some get light bleed no matter what you do.
Cut this adhesive thingy off this old one and use double sided tape or something else on the new one. I bought a high temp double sided tape for many things in the TVs where it's too hot and works fine.
The adhesive on the LED strips? are you saying to peel it off and put it on the new strip? It's not really possible, it starts falling apart into pieces due to the heatsress. It almost gets brittle. Maybe yours had a lot less heatstress was in better condition?
@@NicksTVRepair yes, wasn't nice as well to be true, was time consuming. But, without it, or other replacement, you will have this light which is even worst and customers when see worst, some don't like to pick up the TV even. Had it a number of times in the past.
I have 4 red blinking lights on my LED Sony 65 X900E
Would the fixing would be same as this?
Hello Nelly
4 and 6 blinks are both caused by faulty LED strips
Replacing your LED strips will resolve your issue. We do have the strips still available for sale on our website if you are interested, just check out the links in the video description.

Guys please help! i have sony bravia Model : "KD-65X9004A" The Tv turns on dimmed like the image is on 50% but its full on brightness.. after a minute it slowly turns off and the Indicator Flashes Red 4x times...
what could be the problem ? i can't find any solution regatding this model on the internet also no tutorial or parts for backlight.... any solution?
Sorry we don't work with that model but you do indeed have a bad backlight. 4 blinks means you need to replace your LED strips, we can't help you with that but a local shop might be able to
Will this repair also work for the 55X900C?
Yes it will although we don't have the LED strips for sale for the 55" only the 65
Hello bro I have the same problem like this on my Sony KD65XE9005. Is this method compatible with my model or what should I do? It’s exactly the same problem. Thanks
That will be the same exact problem, but your TV might be a little different and may use slightly different LED strips but the concept will be the same.
@@NicksTVRepair thanks brother. Shall I replace the broken strips or is that the problem of led driver board?
New camera?
The hand held camera used for most of the footage is the one we got from like a year maybe year and a half ago or so, the second one we used was an old camera, actualy it's the camera we used for the very first videos we made from like 3 years ago.

I noticed that the original LED strips were 88 LED strips, whereas the new ones seem to be 64 LED strips. Is that the case? I am planning to replace my strips but my TV has 88 LED strips and I cannot find those.
Will,
Yes that is correct the replacement strips have 64 LEDs vs the originals are 88. I don't know why that is, but there are no manufacturers that remake them with 88 LED's which I don't know why that is the case.
@@NicksTVRepair I finally got around to replacing the LED strips on my TV. After replacing the LEDs the TV still has this weird flickering at different spots of the screen. Like the LEDs turn on and off. I can get those spots to go away if I turn the brightness all the way down to low. Could it be that the LED driver board is malfunctioning? I am not sure if you've had a case like mine. Any help is appreciated.

Hi nick have Sony 55w905a like 8 years now whene open power on see channel and sound play can go and menu and after 30 sec close and blink 4 red what problem think have?
I would recommend watching the video. I answer you question in the first 10 seconds.
Tnx for info I’m check your video but whene open tv never dim screen so not know if any led fail;( you think is my prob is and led driver board?
XBR65-800G - 6 blinking red lights after only 3 years. What a joke. Never buying another (ph)ony product again!
What you have is an LED failure. To fix that you will need to replace the LED strips.
China Backlight ist shit for Sony Ni trilinos
So the more I look into this the more I am finding out it doesn't have to do with the replacement LEDs but the plastic diffuser gets burned up and melted. It seems these replacement LEDs work well with some sets and not as well with others, and the difference seems to be if the plastic diffuser is damaged from the original LEDs going out. Sometimes they don't damage the diffuser sometimes they do and melt it a bit which causes the light bleed.
Use black tape. That will stop the bright light at the bottom of the screen
I have another one of these same sets that just walked in the shop again with 6 blinks. Ill give that a shot and record it. Hopefully that does it.
Thank you!
