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!

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!!!

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.

Awesome. Will try. I posted on the Sony forum that I saw that original video on KZfaq, taken down now, and the person doing it actually added a ring to the end and ground to the screw at the left. I like this way better. Thanks

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 !!!

Thank you! Problem fixed in under an hour! Our TV is working perfectly now after following your instructions.

You are my hero. This tv was in my closet for a year. Pulled out yesterday to see what I could do or to finally throw away and found your video.

Matthew - THANK YOU!. Just picked up a nice 46" Bravio for free today...followed your instructions...and watched a movie on it tonight.

Thank you! It took longer to find your fix than to do it. Very clear and simple instructions that worked.

WORKED!!! good lord sweet baby Jesus! Thank you so much! Very simple easy fix to get you though. Not sure how long it'll last but its working now. Getting the plastic panel off without busting a few clips..... that's a whole other story. Thanks again!

Oh my goodness! It worked! 😭🤗 thank you so much for going the extra mile and making this video! Thank you! ... also for anyone wondering about the tiny cable just pull it out with some pliers and make sure its the right one because there are 2 groups of cables labeled the same

Wow, found your video, followed your instructions, and now my tv works. Thanks

I found this today when I had the same issue. It worked perfectly. Thank you.

This was a super easy fix and saved me tons of time and $$$, thank you!

Worked like a charm!! Now I need to find a replacement leds

Thank you very very much. I almost thrown my TV away and decided to give a one last chance and saw your video. U saved me.

Thanks a bunch. I was following the thread on the Sony forums. I was a bit confused on how exactly to go about this. You're video was immensely helpful. Cheers.

Thank you, Matthew Dart. I've just fixed my TV following your guide. GREAT.

Thanks Bud mines is back up & running its been sitting for 2 years and less than a hour to fix it salute to ya

Thank you you are the man... I followed your steps and got it running 👍🏼👍🏼👍🏼

Thank you, for the straight forward easy instructions. You are the man...

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!

You the man, works as new again...respect

You sir have saved me from spending money on a new tv after this only being 3 years old. Can’t thank you enough 🤘🏻

Dude, you're a legend, thanks so much for the easy fix! My neighbor was going to throw it out but did the fix in 5 minutes. Thank you!

Thank you for posting this! Worked perfectly!

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

Wow! You just saved me a TV!! Worked perfect! Thank you so much! 👍🏻

You actually saved my TV set !!! Thanks so much

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.

Dude....YOU ARE KING....my God....literally tried this last night...BINGO!!!

Yesterday I fixed my Sony KDL-55W905A with your method. Thanks mate!!!

Thanks a lot brother, it worked, fixed in less than 20 minutes. Thank you so much God bless you!!!!!

After years of trying everything on KZfaq 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!

Worked! Thank you so much. Great straight forward video.

Thank you so much!!! Our XBRx65900c is working great thanks to your video!

thank you very much! the video was amazing and sorted everything out! saves time and money

I will have to try this . I've had 4 red blinking lights for over a year . Same no help found till now . Thank you so much .

Thank you, worked perfectly.

OMG, THANK YOU! Worked great, again thanks for saving me thousands of $.

Thanks for your hard work man.

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

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 !!

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!

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 😁

Thank you. I did this and it worked!!!! Thanks!!! Amazing!

Amazing. Thanks. Up and running.

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.

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!!

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.

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!! I was going to buy new TV today, thank you one more time

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...

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

Thank you so much it worked out perfectly. Thanks for clearly explaining the whole process. Yes, SONY no thanks to you!

IT WORKED THANK YOU MATTHEW

It worked!! Thanks dude!!!!

Awesome .. I just fix mine great work

Thank you! This worked perfectly!

Thanks for the video, mine is fixed now.

My tv is doing the same but only when going into 3D mode. Any thoughts on whether this will fix it

@mathewdart Can you make a video showing how to replace the faukty led?

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.

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.

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!

Hello, I have the same tv model, but mine has 2 blinking red lights, can I fix it with these instructions?

@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

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.

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?

does this fix the rebooting problem

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.

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.

I'm going to try this tomorrow. Fingers crossed!

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

Thank you for ur post. It worked!1

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 a lot.. it fixed my tv .. this is what KZfaq was made for

Thank You!

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?

Thank you so much ... This worked. Great video !!! Awesome

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?

@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.

Is it a solid red light or blinking?

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

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

So I think my tv is doing the same thing but I have a XBR-65X900E. Will this fix help my situation??

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

I did like u said......thank you some much

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?

Nice!Going to try this to an 85" 85x900h I got for free because it has the 4 blinking light issue.

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?

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

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!

what does a 6 red blinking sequence mean?

How do u fix bravia 658500g tv flicker

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.

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?

I tried it and it works perfectly. Cut the 2nd wire and grounded to a screw on the board

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.
