I was basically told by Sony, sorry about your luck. I purchased this TV in 2017 after my father has had his Sony Bravia for over 15 years. I had done tons of research prior to purchasing and thought I was getting a quality product from Sony, since the TV was more than $2000. It has spent the past 6 months in a spare bedroom collecting dust until I found this video. I was about to bite the bullet and buy a new TV (not a Sony). I can’t thank you enough for this easy tutorial!
Incredible to hear it worked for you! I received similar treatment from Sony. Apparently the LED fix is too laborious so they write it off. Just turn down the backlight a bit to avoid flickering. Cheers! Mine is still running several years post fix.
Thank you !! 2 years ago My XRB65x900c had this issue 2 days after the extended warranty expired !! Box store wanted $99 just to diagnose repair would be extra ! I boxed it up placed it in the attic (twice it almost went to the dump ). On a whim I search for a repair and found yours !!! Did exactly what you said and less than 20 min this 3k paperweight is fully functioning again !!!
I have a similar story! I’m so glad you stumbled upon this video and you’re operational. Keep your backlight brightness to around 20-25 to avoid any flickering from the dead LED’s. Cheers my friend!
Russell Remley This is fantastic! A year ago I looked everywhere for a fix and when I couldn’t I did the same. Put a blanked over it and put it in the closet. Glad it’s up and running! Cheers
Quickly commenting for everyone - Firstly, for those of whom this worked for, fantastic! This procedure is to circumvent an underlying issue with dislodged or burnt out LED’s at the base of the TV that’s triggering the backlight error. To complete the fix you need to remove all control boards, carefully peel off LED connections and replace the LED panel that’s faulty. This is a far more significant undertaking and the part is difficult and expensive to locate. Typically there are four sets of LED ‘strips’, I’ve only been able to find these strips on eBay but you’d need to validate the part number and proof of functionality. Otherwise if you can deal with one or two dead LED’s you’ve got your TV back. Good luck to all and I’m truly happy some are having success.
Hi! I recently started having a similar issue with my TV as well. The only difference is that mine is blinking 6 times after it shuts down automatically. Would you recommend the same solution as you mentioned in the video? Model is Sony Bravia W60B
Thank you for the assist. This fox worked on my tv today. I had to find another video to show me how to remove the pin using a razor blade. Took me 20 minutes and saved me from having to buy a new pled. Thank you so much.
Thank you so much it really fixed my issue. The Bl_ERR pin on my tv was on the main power board so make sure to find the board that holds that pin with the diagram. Life saver video!!!
Ernest Sharps likewise! This poor TV was sitting in my closet for nearly a year before I was just sick of seeing such a nice TV sit idle. I will say though the backlight does flicker a bit now so it’s not a long term solution but it will keep the tv in service for at least another year or two. Good luck and cheers my friend! Be well.

Tiffany Falk Thank you! I’m so happy this is helping so many people get their TV’s up and running. To believe we spent anywhere from $2-3k on these to have it fail within the first two years of use.

Honest first thoughts while watching your video. Why did it take him 4 months, I found the power supply fix for within 10 min of searching.... Oh... Wait what!?!?... Bypass what.... Shut up! Thank you for taking the time to shoot this video. You have helped out alot of people by doing this. I do not know if it will stay fixed but currently staying on longer than it has before. I liked and subscribed. Happy Corona virus Easter!!
Paul Childers Thank you, Paul! Yeah - I had tried most everything before I found someone on Reddit talking about some unrelated trouble shooting and where breakers might be located and figured the Sony engineers probably built a trip near the LED board to avoid damage due to a power spike. My TV is still going about 5 months in! Cheers and Happy Easter. God Bless...
Ya, the bypass makes perfect sense to see if it is the actual power supply or not. I think my issue is the lower LED strip. Now that it is back on it is a bit discoloration, like a red Hugh. It is not very noticeable, it only is somewhat more noticeable with white backgrounds. I'm going to not tell my wife to see if she can even notice it. Thanks again. Hope yours lasts for more than 5 months, I'm sure it will fingers crossed.
Dude! Your my new hero! You saved me time and money. This worked, and I am very grateful for your time and effort towards research. I have TVs coming in all the time. My son does home theater... Cheers to you!
Thank you for sharing! I did this yesterday and the TV is working much better (so far). Knowing the real problem is the LED strips, I'll regard this repair as an effective "band-aid", buying me time to budget for a replacement TV. Shame on SONY for producing a high-end product with a service life of only 5 years, and no replacement parts available.
Couldn’t agree more! Glad this worked as a temp solution. If you experience flickering in the future with this bandaid reduce the backlight brightness a bit as more LED’s are destined to fail. Chalk it up to poor soldering or quality control. Glad you’re back up and running.
Update - In three week's time, even after setting the brightness to the minimum, the flickering, though inconsistent, degraded to the point where the TV was no longer viewable. Those three weeks did give us enough time to research/select/purchase/install a replacement TV (not SONY). Thanks again for your help.
Matthew thank you ! this needs to be on Sonys Website or they should be paying you!! I was seconds away from tossing the tv thinking there is no hope. Simple easy fix. just gotta give that one wire a little bit to get loose then re connect it into the new port. Thanks again !!
Michael Christopher that’s great news! I’m so glad you were able to salvage it. I assume Sony’s strategy is to just have us buy new ones. I hate seeing a nice piece of technology curbside. Cheers!
Wow wow wow ! Worked like magic. This is really so cool. Thanks Matthew, this video made my day. Though just 1 question that burnt / fuse / malfunction / bad LED cause any problem? Need replacement soon or can leave it as is for long term. For now it works fine, reduce the brightness resolves black flickering issue as well. Thanks again.
Hi Yogesh! I’ve had that BL error re-wired since Nov 2019, so we’re approaching one year without issue. I haven’t experienced any overheating or other issues associated. I’d say it’s rather safe - thinking about the wiring diagram I can’t imagine a massive failure considering the voltage is pretty low. Cheers on the fix! Enjoy your TV again! :)
After years of trying everything on UA-cam fixes and Sony telling me need new motherboard, reddit, forums.. had to get a new tv in the meantime time. 3:34 this fixed mine in 5 mins!!!! 8500g Bravia. Thankyou So much!
Awesome! It makes perfect sense showing that the strip is connected fully to ground. I'm curious, do you have a total black spot on your screen where the LED (which was bypassed) is now black or dark? Also, when you start replacing LED strips please post another video. I've had by KD-70x690e for only two years, and the LEDs are already going out... I have a bunch of purple spots on my screen which is increeeedibly frustrating. Thanks and great video!
Hey! Glad this worked for you. Yes, similarly I can now identify the led strips malfunctioning. Often times if in dynamic mode it’ll flicker far more. I’m working on a full fix but as tv technology improves it may be cheaper in the long run to get a TV set that will stand the test of time. I came across Sony’s new Bravia line and it’s clear they know the problem and have taken design steps to fix it. I’ll keep everyone posted if I get the full fix done. Cheers my friend!
Fixed. Same TV. 4 red lights a few days after the 3 year old threw a cars toy at it. I'd add that a crazy small flathead screwdriver helps get the wire out, then it snaps into the ground port. Also, there isn't any noticeable issues with the screen once if started working again. Seems like Sony's all or nothing approach to back lighting must sell a lot of TVs. Thanks a ton for sharing. Feeling like I should send you a portion of the money I saved 😁
Awesome video man!! I was about ready to chunk this thing out the window. Sony was no help at all and basically useless so I really appreciate the video.
Thank you for your tireless effort you save me a lot of money because it was after the store to get a new TV. I tried all of the service Sony tries of how to fix it nothing worked. So I figured what the heck if I’m gonna have to get a new TV I can just open this one up my mess it up well it was going to be shit canned anyway. The hardest thing for me though is just getting the back of the TV off. The only reason it was difficult for me to get it off is because I am an ex-Navy diver and over 20 years of putting my body to the test I move like a two-year-old child Hooya thank you so much again so happy I don’t have to get another TV great job
@matthewdart Thank you for posting this video.Your video is helpful. My TV also showing Same issue past two weeks.Am using TV from past 4.5 years.I have few questions. How long your TV is running with "BL_error signal is connected to GND"??? Have you seen any issues after connecting to GND??? Explain your observations or issues after connecting BL_ERR connected to GND? Thanks in Advance.
Hope this video was of help. I posted this video the day I performed the change. I’ve seen one inconsistency and have identified the dead LED’s. On occasion, perhaps once per month for a short period I’ll see the LED panel flicker. This is normally resolved within a few minutes. Otherwise no overheating, no shut downs, and best of all, no more error codes.
Thank you Matthew i have noticed this tip. However my Sony is an abravia Lcd and the control for the lamps is the inverter board which i relaced and thought i had suceeded but back to 4 blinks. I have no wire to the error pin from the power board. I think i need to change the main logic board and found a source.Any advce? thank you
Thanks so much for taking the time to post this video your fix worked to get the tv back on but now the screen flashes light and dark shadows. I suspect this is why the 4 red light blinking occurred in the first place. Probably the display board is bad? Any thoughts? Thanks!!
Mark Kuhlenschmidt Hey Mark - that’s right this fix helps get the crux of the issue to determine which LED’s have failed. To me it sounds like the led strip itself is the fault. This is a cumbersome task to replace as they’re underneath the screen. I’m beginning to have full LED strips go out and go dark momentarily and come back on. I really believe this is just a major deficiency in the engineering of the television. This is a common problem with going so thin and not having adequate cooling mechanisms in place. Good luck!
OMG OMG OMG I have been trying to solve this issue for weeks now, I didn't want to take to repairer who doesn't give a shit and basically swap out the mainboard for hundreds of dollars when it doesn't need it. I watched your video and thought that's way too good to be true. I have 2 of these TV's so I was about to start swapping boards to narrow down the issue. I followed the vid and low and behold - working great. Thank you thank you thank you.
Great video. I'm certain that this is the same problem my TV is having. I have a different LED control board. Any idea where I can find the pinout of that cable for my TV, it is not labeled on the board.
Jessie Sandoval tough to tell, they’re typically located on the board itself. Perhaps the bottom right? Or I have seen them displayed along the bottom border. Good luck! And be well!
Hi! Thank you very much for your instructions. I did the same& But now I see shadow light going along the bottom of the screen. How can I solve this issue?
Hey! That shadow light is the reason it was tripping the error code - the final fix is to fully replace the faulty LED strips which quite a bit more cumbersome and difficult to find the parts. I’ve decided to deal with the light bleed and a flicker once in awhile. There are a couple videos on the LED replacement. Good luck my friend!
So...this worked perfectly, thank you! Right up until my wife dropped the flashlight on the screen and broke the screen. I have(d) a KDL-70W830B where there is no clear LED control board, but the white plug going into the power board had two tiers. I moved the BL_ERR wire from the bottom tier over to an open ground port and plugged it in there. Worked until wife tried to help mount it back up on the wall. Yes, still married.
Haha! I’m sorry, this is pretty entertaining. Aron, I’m so glad it worked on your model - nice work on reading that control board gibberish. I’m sorry the TV is now past tense. Still married lol, me too. Cheers!
My friend you are a Lifesaver, God bless you. I was about to trash it, same exact model, you saved me a bundle....on another note... Thanks for nothing SONY...
Had tv up stored away. Saw this vid might give it a shot. How do you change the wire. Physically pull wire by hand? Need tool? Cut? Snap back in on the 9 slot?
Thanks to this post. my TV is working OK now. Black patches shows up at the beginning, than gets back to normal. We will see how long I will be able to use it??
selimgurel63 haha likewise! I have full LED bars flickering a bit which is annoying. It’s been about 6 months so far and that’s the only problem. More of an inconvenience.. be well!
Wow this fix worked for me! Thanks for the video! Unfortunately I replaced my TV before I saw the video.. oh well now what to do with an extra TV.. ( first world problems.. lol) Thanks Mathew!
Max Guzman Awesome! Likewise, I had replaced it and it sat idle in a spare bedroom and I got tired of looking at it and decided to do a little tinkering. Enjoy my friend! Cheers
HI Matt, can you help me with my TV KDL-60W605B Same problem. got the wiring and pins but ERR pin goes directly from power supply board to the main board (no LED control board).
Thanks bro. Had the exact same model, but mines only had three blinks. Regardless, it solved the problem. My TV has been running for over 5 years and hopefully I can get another 5 years now.
hi Mathew, do you happen to know how to do this workaround with the x900e model? big difference in wiring and # of pins. all my attempts have come up empty.
I have an XBR-65X900C that had the 4 blinks problem. I got it to start up and mostly work by changing the LD_ERR pin 2 to pin 9. The previous owner put it in unconditioned storage for a year (causing thermal expansion of the solder joints) after which it stopped working. If I keep it down to brightness level 6/50, only one LED is bad, but turn it up and the rest start flicking on and off. Could I take out the backlight strips and hit them with a heat gun/hair dryer? I'm not skilled at soldering so I'm not sure if that would ruin anything with the flux or not. Honestly I think I would just wait out until I'm ready to spend the money on new backlights and then try it first.
Hi Max - I think you run the risk of compounding the problem if you unseat those LED’s still in contact. Best to do a full replace if you have the time and can locate the part. Similarly I keep the backlight on low still. Best of luck and glad it’s working again.
Jake Hayes the 5 is likely power board or LED driver. I don’t think this fix would work necessarily but it could trigger a different string of operations to get to that Finnish line!
Opened my XBR 900E hoping to try this, the boards inside look different, havent been able to find a video like this for the 900e’s. Any chance you know where the bypass would be on those? This is an awesome video!
I’ve received this question once before but unfortunately I am not sure on the 900 model. Assuming it would be the ribbon going into the LED driver board. Ground wire is normally more easy to identify.
I have an KD 65XE8596. it doesn't have a back light or chip board for it. But on the main power board it does have (cn6401_8) BL_ERR. Will it work the same?
Just a reach out for the XBR65x900c 4 blinking light ERROR SUFFERERS. It is the LED strips (3) that go bad. I found a guy on eBay who offers the service deal where you send in the strips for repair and ships them back to you..WORKED..Of course you have to get in there slowly and remove them to ship.
@@minnesota7010 i did. Just open the back panel and take a video or pics of every component position and place all the screws in baggies labeling them for reinstall. Remove every board slowly and carefully remove the strips and pack them with bubble wrap prior to shipping them in a oversize box. Good luck..Treat it as a puzzle off and on again.. Good luck..
I am a bit confused about how to read the pins from my servicing manual for my KD-55XE9005. It says my BL_ERR is at pin 27 on my main board, but I am not sure which way around that would be?
I have a Sony x900h and I see the pin but it’s smaller than the ones on your TV so I’m wondering is there a way to push or pull them out without breaking the wire, I’m having the hard time right and the damn wire won’t come out
I have the same 4 red blinking light issue with a Sony XBR49x900E but have no legend on any of my boards and can’t quite isolate which pin/wire to pull. Haven’t been able to find any videos addressing this model. Bought a new power board I am waiting on to see if that helps. Meantime, living room TV is disassembled on the living room floor. Anyone else? Thanks much!
LI JUNG CHANG - Hey! It’s a little tricky. If you have something pointy you can wedge it in to dislodge. There is also a tension clip on the outside. Just be sure it’s unplugged! Best of luck and be well!
Hey, Matthew i was just given a Sony XBR-65X900C with the dreaded 4 red light blinking routine. Should i plug the #2 error wire into a ground plug or cut strip and attach to the board screw on the left? Does it make a difference?..Thanks
John Nisyrios Hey John! Yeah, the more stock approach is to dislodge that position 2 BL_Err pin and place it into an empty ground slot. I have seen some just strip and wrap on a nearby grounded screw. Both options seem to work but I would prefer the stock approach in the long run in the event of a major static discharge. Let me know how it goes - I think you might have lucked out with acquiring the tv!
@@TheDarticus it worked as described. BUT the bottom black flashes have begun intermittently , I assume that some of the backlight bar leds are bad. I searched and that is one tough part to find any repair suggestions?..Thanks
John Nisyrios Hey John, it’s likely the bar next to the mid point that’s flickering. I’ve found that’s where most of the heat is. I toyed with the idea of ordering the part from EBAY but they’re very hard to locate and you’d need to prove its operational. There is a video online that walks through changing out the LED strip in Spanish. I haven’t been successful at actually acquiring the part and Sony won’t sell it to you. I have considered heating up the bottom of the television with a heat gun and trying to reseat the LED’s but haven’t gotten around to trying.
hello. i heard from many tv technicians, its bad to bypass the backlight error wire, it could heat up or could be set on fire inside, if we bypass that protection.is it true?
Very interesting information sir, i have a Sony BraviaKDL40R470B it was giving4 red blinks i replaced the TCon board which i found was wet, the tv starts up then without the 4 blinks, then quickly goes into the 4 blinks is it possible you may know what the problem could be. Thanks
Hey there so I have an xbr85x850d that does not show display what so ever, and 8 red blinking lights My tv has two powersupplys like this one, i cut the middle power supply wire one bl_err and grounded it and did nothing just stnd by light turns on then shuts off like usual. Any suggestions
This worked to correct the 4 error lights. But, now there are shadows flashing across the screen. These shadows sometimes disappear briefly, but always come back. How do I fix that? I have already adjusted backlighting and color down to reduce intensities to no avail.
Sony XBR65x900E has different board layout but I am getting the four blinking red lights. Will grounding out the BL_ERR wire work on this model? If so, where is it? The boards are not marked like the XBR65X900C. Thanks
spdboat33 yes, the tv would turn on and display the android animation for about 10 seconds or less. Then you could audibly hear the power board shut down followed by 4 repeating red blinking lights in sequence.

Michael Christopher that’s great news! I’m so glad you were able to salvage it. I assume Sony’s strategy is to just have us buy new ones. I hate seeing a nice piece of technology curbside. Cheers!
the tv is still working in 2024?
Yup just got mine up been down nearly 5years this worked a charm easy to unpin plug and slot it in a ground happy days some one buy this man a drink
Cheers!!
Wow, found your video, followed your instructions, and now my tv works. Thanks
Dude....YOU ARE KING....my God....literally tried this last night...BINGO!!!
Cheers my friend! Glad you’re back up and running.
I did it and it done. Thank you, thank you, thank you sooooo mach!
Wow wow wow ! Worked like magic. This is really so cool. Thanks Matthew, this video made my day.
Though just 1 question that burnt / fuse / malfunction / bad LED cause any problem? Need replacement soon or can leave it as is for long term. For now it works fine, reduce the brightness resolves black flickering issue as well. Thanks again.
Hi Yogesh! I’ve had that BL error re-wired since Nov 2019, so we’re approaching one year without issue. I haven’t experienced any overheating or other issues associated. I’d say it’s rather safe - thinking about the wiring diagram I can’t imagine a massive failure considering the voltage is pretty low. Cheers on the fix! Enjoy your TV again! :)
After years of trying everything on UA-cam fixes and Sony telling me need new motherboard, reddit, forums.. had to get a new tv in the meantime time.
3:34 this fixed mine in 5 mins!!!!
8500g Bravia.
Thankyou So much!
Wahoo! Cheers friend. Paperweight no more.
you just bypass an error message, this doesn't fix the real problem for that error message (red blink led) appears.
Awesome! It makes perfect sense showing that the strip is connected fully to ground. I'm curious, do you have a total black spot on your screen where the LED (which was bypassed) is now black or dark?
Also, when you start replacing LED strips please post another video. I've had by KD-70x690e for only two years, and the LEDs are already going out... I have a bunch of purple spots on my screen which is increeeedibly frustrating.
Thanks and great video!
Hey! Glad this worked for you. Yes, similarly I can now identify the led strips malfunctioning. Often times if in dynamic mode it’ll flicker far more. I’m working on a full fix but as tv technology improves it may be cheaper in the long run to get a TV set that will stand the test of time. I came across Sony’s new Bravia line and it’s clear they know the problem and have taken design steps to fix it. I’ll keep everyone posted if I get the full fix done. Cheers my friend!
This was a super easy fix and saved me tons of time and $$$, thank you!
Yesterday I fixed my Sony KDL-55W905A with your method. Thanks mate!!!
izuniapiotr Awesome! Cheers 🍻
still working today in 2024?
Worked like a charm!! Now I need to find a replacement leds
Fixed. Same TV. 4 red lights a few days after the 3 year old threw a cars toy at it. I'd add that a crazy small flathead screwdriver helps get the wire out, then it snaps into the ground port. Also, there isn't any noticeable issues with the screen once if started working again. Seems like Sony's all or nothing approach to back lighting must sell a lot of TVs. Thanks a ton for sharing. Feeling like I should send you a portion of the money I saved 😁
Reading this comment is compensation enough. So glad we’ve salvaged another. Cheers my friend!
Thank you, Matthew Dart. I've just fixed my TV following your guide. GREAT.
Wonderful! Cheers
Hey Matthew that fix mine I couldn't believe it!! That's worth giving you a 100.00 dollars compared to what a new would have cost!! Thanks man.
Cheers my friend! We’re here to help one another.
When you say cheers would you happen to be from Australia?
David Hardin haha no, habit. Just love an ice cold ale!
@@TheDarticus LOL. Just been there before its nice over there. Thanks again take care.
Thank you so much!!! Our XBRx65900c is working great thanks to your video!
Jessica Kutsko awesome!!! Be well
Hey there... is your TV still working? Thinking about doing the repair.
still working in 2024?
Awesome video man!! I was about ready to chunk this thing out the window. Sony was no help at all and basically useless so I really appreciate the video.
You’re welcome! Glad it’s still helping.
You actually saved my TV set !!! Thanks so much
Happy this helped, Amir!
Thank you for your tireless effort you save me a lot of money because it was after the store to get a new TV. I tried all of the service Sony tries of how to fix it nothing worked. So I figured what the heck if I’m gonna have to get a new TV I can just open this one up my mess it up well it was going to be shit canned anyway. The hardest thing for me though is just getting the back of the TV off. The only reason it was difficult for me to get it off is because I am an ex-Navy diver and over 20 years of putting my body to the test I move like a two-year-old child Hooya thank you so much again so happy I don’t have to get another TV great job
Thomas Powell thank you so much, Thomas! Bless you my friend. Be well!
Thank you, for the straight forward easy instructions. You are the man...
Cheers my friend! Glad you’re up and running.
@matthewdart Thank you for posting this video.Your video is helpful.
My TV also showing Same issue past two weeks.Am using TV from past 4.5 years.I have few questions.
How long your TV is running with "BL_error signal is connected to GND"???
Have you seen any issues after connecting to GND???
Explain your observations or issues after connecting BL_ERR connected to GND?
Thanks in Advance.
Hope this video was of help. I posted this video the day I performed the change. I’ve seen one inconsistency and have identified the dead LED’s. On occasion, perhaps once per month for a short period I’ll see the LED panel flicker. This is normally resolved within a few minutes. Otherwise no overheating, no shut downs, and best of all, no more error codes.
Thank you for posting this! Worked perfectly!
Thank you Matthew i have noticed this tip. However my Sony is an abravia Lcd and the control for the lamps is the inverter board which i relaced and thought i had suceeded but back to 4 blinks. I have no wire to the error pin from the power board. I think i need to change the main logic board and found a source.Any advce? thank you
Thank you you are the man... I followed your steps and got it running 👍🏼👍🏼👍🏼
Thanks a lot brother, it worked, fixed in less than 20 minutes. Thank you so much God bless you!!!!!
Gary Arenas Thank you for watching, I’m so glad it worked out well for you! God Bless my friend.
Wow! You just saved me a TV!! Worked perfect! Thank you so much! 👍🏻
Great to hear my friend! Enjoy
Thanks so much for taking the time to post this video your fix worked to get the tv back on but now the screen flashes light and dark shadows. I suspect this is why the 4 red light blinking occurred in the first place. Probably the display board is bad? Any thoughts? Thanks!!
Mark Kuhlenschmidt Hey Mark - that’s right this fix helps get the crux of the issue to determine which LED’s have failed. To me it sounds like the led strip itself is the fault. This is a cumbersome task to replace as they’re underneath the screen. I’m beginning to have full LED strips go out and go dark momentarily and come back on. I really believe this is just a major deficiency in the engineering of the television. This is a common problem with going so thin and not having adequate cooling mechanisms in place. Good luck!
OMG OMG OMG I have been trying to solve this issue for weeks now, I didn't want to take to repairer who doesn't give a shit and basically swap out the mainboard for hundreds of dollars when it doesn't need it. I watched your video and thought that's way too good to be true. I have 2 of these TV's so I was about to start swapping boards to narrow down the issue. I followed the vid and low and behold - working great. Thank you thank you thank you.
Cheers my friend! So glad you’re back up and running.
still working today in 2024?
Thanks for your hard work man.
Great video. I'm certain that this is the same problem my TV is having. I have a different LED control board. Any idea where I can find the pinout of that cable for my TV, it is not labeled on the board.
Jessie Sandoval tough to tell, they’re typically located on the board itself. Perhaps the bottom right? Or I have seen them displayed along the bottom border. Good luck! And be well!
Matthew Dart, any luck finding the pin out diagram? I am in the same boat here as well. I looks like SONY intentionally stop labeling these boards.
Hi! Thank you very much for your instructions. I did the same& But now I see shadow light going along the bottom of the screen. How can I solve this issue?
Hey! That shadow light is the reason it was tripping the error code - the final fix is to fully replace the faulty LED strips which quite a bit more cumbersome and difficult to find the parts. I’ve decided to deal with the light bleed and a flicker once in awhile. There are a couple videos on the LED replacement. Good luck my friend!
OMG, THANK YOU! Worked great, again thanks for saving me thousands of $.
Cheers!
Worked! Thank you so much. Great straight forward video.
Wow thank you. I would love to try this. Before I dismantle the TV...mines a Sony XBR-55X850C . Do you think it could work?
thank you very much! the video was amazing and sorted everything out! saves time and money
My tv is doing the same but only when going into 3D mode. Any thoughts on whether this will fix it
So...this worked perfectly, thank you! Right up until my wife dropped the flashlight on the screen and broke the screen. I have(d) a KDL-70W830B where there is no clear LED control board, but the white plug going into the power board had two tiers. I moved the BL_ERR wire from the bottom tier over to an open ground port and plugged it in there. Worked until wife tried to help mount it back up on the wall. Yes, still married.
Haha! I’m sorry, this is pretty entertaining. Aron, I’m so glad it worked on your model - nice work on reading that control board gibberish. I’m sorry the TV is now past tense. Still married lol, me too. Cheers!
My friend you are a Lifesaver, God bless you. I was about to trash it, same exact model, you saved me a bundle....on another note... Thanks for nothing SONY...
phantastik7 Awesome!! So glad this worked for you as well. We are all engineers at heart. God Bless my friend! Cheers
@mathewdart Can you make a video showing how to replace the faukty led?
Had tv up stored away. Saw this vid might give it a shot. How do you change the wire. Physically pull wire by hand? Need tool? Cut? Snap back in on the 9 slot?
Apply a little force and I believe there is a small lever in the front it’ll shimmy loose. Good luck
Thanks to this post. my TV is working OK now. Black patches shows up at the beginning, than gets back to normal. We will see how long I will be able to use it??
selimgurel63 haha likewise! I have full LED bars flickering a bit which is annoying. It’s been about 6 months so far and that’s the only problem. More of an inconvenience.. be well!
Wow this fix worked for me! Thanks for the video! Unfortunately I replaced my TV before I saw the video.. oh well now what to do with an extra TV.. ( first world problems.. lol) Thanks Mathew!
Max Guzman Awesome! Likewise, I had replaced it and it sat idle in a spare bedroom and I got tired of looking at it and decided to do a little tinkering. Enjoy my friend! Cheers
I spent hours looking for a solution. This worked for me after having the tv sir for over 1 year. Great video! Simple solution
My tv: kdl-60w840b
Fantastic, Sir Rahman! Glad you’re back in business. Cheers
still working in 2024?
IT WORKED THANK YOU MATTHEW
Thank you! Be well!
HI Matt,
can you help me with my TV KDL-60W605B Same problem. got the wiring and pins but ERR pin goes directly from power supply board to the main board (no LED control board).
Thanks bro. Had the exact same model, but mines only had three blinks. Regardless, it solved the problem. My TV has been running for over 5 years and hopefully I can get another 5 years now.
Cheers! I’m still running strong. 1yr since fix, 5yrs on the TV in total. Enjoy brother.
hi Mathew, do you happen to know how to do this workaround with the x900e model? big difference in wiring and # of pins. all my attempts have come up empty.
Any luck with this in the 900e?
I have an XBR-65X900C that had the 4 blinks problem. I got it to start up and mostly work by changing the LD_ERR pin 2 to pin 9. The previous owner put it in unconditioned storage for a year (causing thermal expansion of the solder joints) after which it stopped working. If I keep it down to brightness level 6/50, only one LED is bad, but turn it up and the rest start flicking on and off. Could I take out the backlight strips and hit them with a heat gun/hair dryer? I'm not skilled at soldering so I'm not sure if that would ruin anything with the flux or not. Honestly I think I would just wait out until I'm ready to spend the money on new backlights and then try it first.
Hi Max - I think you run the risk of compounding the problem if you unseat those LED’s still in contact. Best to do a full replace if you have the time and can locate the part. Similarly I keep the backlight on low still. Best of luck and glad it’s working again.
Hello, I have the same tv model, but mine has 2 blinking red lights, can I fix it with these instructions?
Matthew, I have the XBR-65X900E model that is throwing a 5 blinking LED light error. Think grounding out the backlight error wire would work for mine?
Jake Hayes the 5 is likely power board or LED driver. I don’t think this fix would work necessarily but it could trigger a different string of operations to get to that Finnish line!
Opened my XBR 900E hoping to try this, the boards inside look different, havent been able to find a video like this for the 900e’s. Any chance you know where the bypass would be on those? This is an awesome video!
I’ve received this question once before but unfortunately I am not sure on the 900 model. Assuming it would be the ribbon going into the LED driver board. Ground wire is normally more easy to identify.
Thank you, worked perfectly.
Thank you. I did this and it worked!!!! Thanks!!!
Amazing!
@Matthew Dart I took out the pin and put it in pin 9 but all I see a white light and black screen please help
will this work for a XBR-65x850A????
I have the 4 red blinking lights no picture at all and I am able to hear the background noise
It worked!! Thanks dude!!!!
I have an KD 65XE8596. it doesn't have a back light or chip board for it. But on the main power board it does have (cn6401_8) BL_ERR. Will it work the same?
thank you so much i have a newer version of the sony bravia and this how to worked a treat thumbs up from me thanks
Fantastic! Have a beautiful day.
Just a reach out for the XBR65x900c 4 blinking light ERROR SUFFERERS. It is the LED strips (3) that go bad. I found a guy on eBay who offers the service deal where you send in the strips for repair and ships them back to you..WORKED..Of course you have to get in there slowly and remove them to ship.
@@minnesota7010 I feel for you..The TV still runs..Here is the ebay item #264743323420
@@johnnisyrios9668 thanks buddy John who put the LCD light strips in for you did you do it or did you bring it in to have someone work on it.
@@minnesota7010 i did. Just open the back panel and take a video or pics of every component position and place all the screws in baggies labeling them for reinstall. Remove every board slowly and carefully remove the strips and pack them with bubble wrap prior to shipping them in a oversize box. Good luck..Treat it as a puzzle off and on again.. Good luck..
I am a bit confused about how to read the pins from my servicing manual for my KD-55XE9005. It says my BL_ERR is at pin 27 on my main board, but I am not sure which way around that would be?
I have a Sony x900h and I see the pin but it’s smaller than the ones on your TV so I’m wondering is there a way to push or pull them out without breaking the wire, I’m having the hard time right and the damn wire won’t come out
I have the same 4 red blinking light issue with a Sony XBR49x900E but have no legend on any of my boards and can’t quite isolate which pin/wire to pull. Haven’t been able to find any videos addressing this model. Bought a new power board I am waiting on to see if that helps. Meantime, living room TV is disassembled on the living room floor. Anyone else? Thanks much!
Amazing. Thanks. Up and running.
Hi Matt,
How do I remove the cable? I tried to pluck it with my hand but it’s not coming out. Should I use a tool of some kind?
LI JUNG CHANG - Hey! It’s a little tricky. If you have something pointy you can wedge it in to dislodge. There is also a tension clip on the outside. Just be sure it’s unplugged! Best of luck and be well!
I’m trying to figure out how to remove the cable as well. Can anyone offer me any suggestions
Hey, Matthew i was just given a Sony XBR-65X900C with the dreaded 4 red light blinking routine. Should i plug the #2 error wire into a ground plug or cut strip and attach to the board screw on the left? Does it make a difference?..Thanks
John Nisyrios Hey John! Yeah, the more stock approach is to dislodge that position 2 BL_Err pin and place it into an empty ground slot. I have seen some just strip and wrap on a nearby grounded screw. Both options seem to work but I would prefer the stock approach in the long run in the event of a major static discharge. Let me know how it goes - I think you might have lucked out with acquiring the tv!
@@TheDarticus it worked as described. BUT the bottom black flashes have begun intermittently , I assume that some of the backlight bar leds are bad. I searched and that is one tough part to find any repair suggestions?..Thanks
John Nisyrios Hey John, it’s likely the bar next to the mid point that’s flickering. I’ve found that’s where most of the heat is. I toyed with the idea of ordering the part from EBAY but they’re very hard to locate and you’d need to prove its operational. There is a video online that walks through changing out the LED strip in Spanish. I haven’t been successful at actually acquiring the part and Sony won’t sell it to you. I have considered heating up the bottom of the television with a heat gun and trying to reseat the LED’s but haven’t gotten around to trying.
Yeah that ONE GUY was the only one who had it right! The #2 wire re located to #9 ground . Worked like a charm on
my Sony XBR900C.
hello. i heard from many tv technicians, its bad to bypass the backlight error wire, it could heat up or could be set on fire inside, if we bypass that protection.is it true?
Very interesting information sir, i have a Sony BraviaKDL40R470B it was giving4 red blinks i replaced the TCon board which i found was wet, the tv starts up then without the 4 blinks, then quickly goes into the 4 blinks is it possible you may know what the problem could be. Thanks
You can open led srtip and check for loose led soldering to the strip because it is because of one or more non-functioning led(in my opinion ).
briekhnaa you’re absolutely right. If it weren’t so difficult gaining access to those LED strips would make life quite a bit easier!
Thanks a lot.. it fixed my tv .. this is what UA-cam was made for
Thank you so much it worked out perfectly. Thanks for clearly explaining the whole process. Yes, SONY no thanks to you!
Ly Tin Hey, Ly Tin! So glad it worked out for you. Enjoy! Cheers
Hey there so I have an xbr85x850d that does not show display what so ever, and 8 red blinking lights My tv has two powersupplys like this one, i cut the middle power supply wire one bl_err and grounded it and did nothing just stnd by light turns on then shuts off like usual. Any suggestions
Thank you!!
I was going to buy new TV today, thank you one more time
stil working today in 2024?
This worked to correct the 4 error lights. But, now there are shadows flashing across the screen. These shadows sometimes disappear briefly, but always come back. How do I fix that? I have already adjusted backlighting and color down to reduce intensities to no avail.
Sony XBR65x900E has different board layout but I am getting the four blinking red lights. Will grounding out the BL_ERR wire work on this model? If so, where is it? The boards are not marked like the XBR65X900C. Thanks
I also have BL_ERR(G) - anyone know which one?
Exact same thing for me. Model and all.
I'm having the same problem with XBR-85X900H, not sure which wire is the #1. I have a picture of mine but not able to attach on here. Need help
ua-cam.com/video/uZ5pscn8c2Q/v-deo.html
Thanks for the video, mine is fixed now.
Tracy Medford Great! Cheers
So I think my tv is doing the same thing but I have a XBR-65X900E. Will this fix help my situation??
Did your tv have the 4 animated icons on the screen before the red LED started flashing?
spdboat33 yes, the tv would turn on and display the android animation for about 10 seconds or less. Then you could audibly hear the power board shut down followed by 4 repeating red blinking lights in sequence.
Awesome .. I just fix mine great work
