Just like everyone else my Sony TV started flashing the red lights just after the two year mark. So of course Sony wouldn't help.
This 100% works! Thank you!
Happy to hear this helped you
Thank you Nick. Mine is the KD55-A1 so a little more involved taking the back off and disconnecting several banks of cables and locating the power block. Not much detail in regards numbering on the plug so came from the right, removed the second wire (white) and popped it into the only blank hole where the grounded (grey) wires. Reassembled and crossed fingers. No explosion, hard reset.....seems to be working perfectly!
Wow that is surprising. This is not supposed to work for other sets as the way LEDs fail typically means they actually failed. WIth this unit because they used a different type of led system that is very sensitive, the fault code would get triggered even though the LEDs still had plenty of life left in them.
@@NicksTVRepair it’s been on for about an hour; hasn’t switched itself off and no four red flashes. I literally have winged it if it isn’t supposed to work! The power pack is covered by another metal plate which I had to unscrew, rotate 90 degrees, pull out a bank of plugs to do the final turn. Small bank of wires with only one blank space in the grey wire section. I just thought, what’s the worst thing that could happen! 😂 I’ll let you know if it fails 👍
PS. It was start in there so blasted it with a can of compressed air too.
Well replaced the LEDs and TV has been working no issues for over 3 hours, doing a LED replacement was no easy feat those things are stuck on with some damn strong adhesive, but @Nick thank you for the advice and support
You are very welcome! I am happy to help!
Legend, fixed the 10 year old sony 46" 46w900a bravia tv that has been sitting in storage for a year.. THANK YOU!
My wire layout was different but i found it pretty easily.
Glad it helped!
Yeah every TV has a slightly different set up but the legend and markings are usually fairly clear and easy to follow.
Thanks so much for your in depth explanations. I have an xbr65a9g and am looking for led strips, but don’t see them in your store.
I am sorry to inform you that you won't be able to purchase LED's for your TV set.
The TV you have is an OLED TV which does not have LED strips. The LED's are a part of the screen. If you have an LED malfunction you will need to replace the screen which is not cost effective.
Good info. When I opened my 65x939E though there are two power supply board and one is labeled secondary. On both board I have a connectors that labels bl_err(g) but they are connected to each other. Thee is a different connector that for the vled_gr and vled_vcc. Should i take off both bl_err and connect them both to ground?
Thank you for your question. You will only need to take off the BL_ERR.
Hey Nick - Great video. I replaced the backlight led's but now getting sound but no video - any ideas ? Connectors are all good. Thank you!!
It is very easy to miss a connector or ribbon plug, or even to not have missed one, but a ribbon is not plugged in exactly perfectly. Double check all your cable connections, disconnect and reconnect them, same with the ribbons, and try again. Some of these are sensitive, so that may be all you need to fix the issue.
There is no reason for there to be no picture after replacing the backlight unless either one of the connectors isin't properly inserted, or there is infomration missing.
Did you turn the TV on while the screen was removed and disconnected from the T-con and mainboard for example? If so the panel could no longer be paired with the T-con and mainboard and may need to be paired again.
If that is the case, then check the video linked below:

Hi Nick, I have a KD-75F9005, with I 4 x Red blink, I really need help here, I have already replaced the Tcon and the LD driver board, but still the same issue, iv also tried grounding the BL_ERR cable, the thing is this TV has two PSU so I'm not sure an I meant to ground all going to power or the BL_ERR coming from the main board.
This trick only works for the 900c series TVs. To fix your TV, you will need to replace the LED strips.
Hi Nick - This was helpful, and my TV does power on. But after a couple minutes, I start seeing dark spots and or LED flickering. I assume this is because I need to replace the LED light or strips somewhere. Do you have a video on how to do this? I have the XBR-65X900C
I do not have a video on the LED replacement at this time. We may have one in the future but as of right now, I would say to look around on different channels, I think a few other people have videos on it.
Hi, Would a Sony kd70x690e that has the LED light at bottom blinking 6 times be fixed the same way as the video ??? Also, I assume you're connecting the Negative/Black lead of the meter to the Chassis/ground of the TV ? Thank you.
No and yes.
No in the sense that doing this won't fix your TV because your TV is a backlit tv whereas this one in the video is edglit and fails very differently. This trick really only works for this model only. You can still short out your BL-ERR to ground and it will prevent the 6 blinks from coming up and the set from shutting down but if your LEDs are bad, either the LEDs won't light up at all or you will have a dark spot on the screen.
For your TV set, you will want to replace the LED strips to fix the set.
As for the Negative lead, you can use the chassis ground if you would like yes, that works.
Hi, there is no available ground position to plug the BL Err. Can i ground it anywhere else, like on a screw at the corner of the PS board? thanks
That would work as well
I did it that and it done. Thanks a lot !
You're welcome!
Hi Nick, Sony xbr 55X900C , I removed pin number 2 and put it in pin 9 grnd.as per your video but it did not resolve the issue, android logo comes and TV shuts and has 4 blinking lights. please advise any other quick fix possible . thanks
This should prevent the 4 blink from getting triggered. Even if your LED strips were completely failed you would not get the 4 blink code with this jumper.
Alternatively you can also replace the LED strips.
You are amazing,man! Thank you!!
You are very welcome, and thank you for watching!
excellent tutorial, verbage & visual right on point👍 thank you
Thank you for the feedback, it is much appreciated.
Excelent video!
My tv Sony kd-49x705e turn off, and blinking 4 times the red led.
Can i do this to solve the problem?
Tanks so much.
You can try but it will have a different pin out so you will need to figure out where each of those pins is located by checking the legend on your power supply. It may not work depending on how your strips have failed.
@@NicksTVRepair I Try it! Tanks so much! 🤘🏻🤘🏻🤘🏻🤘🏻🤘🏻
Hi Nick, thanks for the video, I have a sony k75x9400D and this method didn't work. what will be next? Power board looks ok as I can run the Reset. Is it DPS board or something else? Thanks in advance.
If you have a 4-6 blink fault and this didn't work, then you will haev to replace the LED strips.
Hi Nick. I have a XBR-65X900C and while watching tv, i get a thick purple and white bards on my screen. Sometimes its black and white. I tried everything including replacing the HDMI and hard reset. Any suggestions ? I hear the whatever is playing on the background still.
I have to say I have never heard of this before, I am not sure I know what could be causing this. You could have a screen failure, a T-con board failure, or a mainboard failure. Unfortunately without having access to the TV, I don't know that I would be able to assist further.
What I can tell you is that replacing the T-con board would be the cheapest option. Then the mainboard, but unfortunately the screen is not worth replacing.
If you do try replacing the T-con and mainboard, I suggest purchasing from a seller that would allow returns.
Good luck
For the XBR 900e’s the boards look dofferent when I opened the back, and doesnt seem to have a guide to which the backlight error wire is, do you happen to have a guide or know which the backlight error wire may be on those? This video is great
This video is only applicable to the 900C model. This repair does not work with any other tv than the 55" and 65" 900C models.
If you have a 4 or 6 blink code with other Sony models then you have to replace the LED strips to fix it.
I ran into that problem with the 900e ONCE where it turned out the tv was doing a software update and something happened according to the customer. And started giving the error code for issue with inverter or LED. Turns out that the software got corrupted during the update and was making the main board give false codes. TV would turn on for 10 to 12 seconds sometimes show the Sony logo then shut down. The fix was a hard reset. Unplug tv hold power power button on front of tv while pluging in power cord and wait til tv turns on then release power button. Which in this RARE case fixed the tv. Like I said rare. Seems these newer android/Google Sonys have a lot of software issues. It was a nice cheap fix for the customer.
@@docgonzo1973I have a XBR-49X900F and the procedure you described didn't work for me. I guess my LED strips need to be replaced but thank you for the information as it described my situation exactly. My TV won't come on after the hard reset. So I tried to reload the software which said it completed. When booting up I have gotten as far as the setup screen (like when you first got it) and then it clicks off, blinking red 4 x's. I get further each time though.
So I just bypassed this pin myself until I get new strips to come in (i am not equipped to resolder all of those joints).... Maybe it was there the whole time or maybe it is new... but if i put an all white screen up i get some sever orange coloring bleeding from the bottom up. What would this be and will it resolve when I put in new strips? Does this have to do with burn LEDs or what?
The orange coloring will not be fixed with the new strips, this is an issue I do not know how to resolve unfotunately.
It worked on my 65X850B, but I wanna really know what the issue is: I removed the power cable going to the LD board and powered on the TV, still powered off with 4 blinks. I then reconnected power to LD board, removed cables going from TCON board to panel, TV shut off. I removed 2 cables going from main board to TCON board, powered on, TV stayed on. Is the issue TCON board?
Hello!
The issue isn't the TCON, it's the PSB unfortunately.
Hey, so i actually have to pins one small with 4 lots and 2 wires plugged in, and another with 8 lots amd 6 wires, could u help woth which wire where
If you have a different model TV then most likely this trick won't work for you. It only works with this model TV shown in this video
Do you have any simular fix for the Sony OLEDs? My TV (XBR-65A8G) just shut off yesterday and now all I get is a continuous red blinking light in groups of 4, and unfortunately I live overseas, which doesn't service my American model😢
Thanks in advance, BTW I love your videos, keep up the good work!
Thanks for the feedback.
I don't have a video for the OLED models. Those are a bit different than this TV which has edge lit LED strips.
I don't know that this would work with your set unfortunately.
I think this might be the ticket for me. panel lights up on boot on my xr-65x90j then switches off to 4 red blinks... You don't happen to have the pinout for what I'd need for that model do you? Which pin on the led board am I grounding out? and which pin is ground :) thank you!
look at your power supplie's legend and do the same pins as what I do in the video. They may be in different locations but it's still the BL_ERR and GND.
Also this trick doesn't work on all sets, it primarily works on this set because of the way the LED's are designed. It may not work for you at all on the x90J since it uses different types of LEDs.
Hello Nick. Nice video. May i ask , Can you tell me how many volts each SMD LED chip on the Sony XBR-55X900F LED bar works with and its name, and the datasheet link if available? It consists of 9 LED bars and each LED bar contains 15 SMD LEDs.
These are very specific questions. I would have to spend a significant amount of time to get this information. I am sorry I just don't have the time to do that for you. I would recommend talking to someone that manufactures the strips if I were you. They may have that information already available.
@@NicksTVRepairI agree with you, you work professionally and time is money. I asked if you had any information. Thank you very much for your reply.
hello Nick, do you know which pin is the protection line of a 55XD9305. tv standby flashes red 4 times. this tv has an led driver and a dps board
I already responded to this exact question which you posted on 3 different videos.
I have the XBR-65X900A, the TV turns off but it could take a few hours or just maybe a few minutes and then I get the 4 blinking lights. I got into the error code screen and I see there are 30 errors for the VLED and 4 for the LD_ERR. Also, when watching a 3D movie, within minutes the picture starts turning dark and the TV turns OFF. My service manual shows the BL_ERR and the LD_ERR pins on the CN6602 connector (MAIN POWER AND CONVERTER BOARD) and CN6402 (PFC, PRI_VCC AND STANDBY POWER SUPPLY). But your video talks about grounding the BL_ERR on the MAIN BOARD. In my case it is CN9101 PIN 20. I already tried grounding BL_ERR on connector CN6602 and that just will make the TV turn OFF as soon as you turn it on. My question is, do I ground the BL_ERR on CN9101 (MAIN BOARD - BAFS)?
Your TV set is different than the ones I am going over in the video so it is likely that you will need to do something differently to make it work on your set.
If you are grounding the BL-ERR pin and it makes the TV turn off, something was not done properly. Grounding the BL-ERR pin should not cause the set to shut off regardless of which connector it is done on.
As well if this is an issue that takes a few hours before it comes up, you may not need to ground the BL-ERR pin, and instead only need to turn down the backlight in the setting on your TV to resolve the issue. Not the brightness, but the backlight. This should be found under your picture settings, sometimes hidden in the advanced picture settings.
@@NicksTVRepair Thank You so much for your quick response. I have tried turning down the backlit settings and also turned OFF the ECO light sensor setting, but that does not solve the issue. Watching a 3D movie will turn off the TV within seconds to a couple of minutes. Watching regular TV, will stay On for a while. Here is a link to the block diagram of the boards and pins from the service manual. I tried grounding the BL_ERR on the CN6602 board but that will not make the TV stay on. In your video you say to ground the BL_ERR on the Main Board, I have not tried that because on your video it shows you grounded BL_ERR on the CN6602 board, but that is not the main board. In my case it is the Main Power AND Converter board. See link .

Thanks again for your help.
Is there any chance you know which pin is for Bl_err on the x900e? They use a different power board
It won't work with the 900E model
Hi Nick - i have a 850 G -65 inch from costco purchased 10/2019.
I tried grounding pin 8 (BL-ERR) but didnt work. It won’t even power on. When i put pin 8 back in the ribbon cable,it powers up but then goes to six red blinks.
Not sure what else to do?
Replace your LED strips
I have sony kd 55a1 oled, can you help me bypass the four flashing red lights, bl_err cable.
Unsure, as we do not have personal experience with bypassing this but check the LD_ERR_DET pin.
For the XBR-900C that particular pin will have 1.9 volts and above if it has an error. Maybe it will be the same for your model. You'll have to confirm with your multimeter.
Thanks a lot for the video! I have a similar model with the same problem. Do you know if there are some long term effects for the LED driver or power supply? Like burning a transistor or other component from too much current demand. Or will the LED strip fail before them? Thanks :)
NO it will not damage any other components.
There is no excessive current demand and doing this will not trigger any additional current demand from the LED strips. If anything the LEDs are not demanding enough current. When the LEDs go over the edge what will commonly happen is you get strobing from the LEDs. There won't be any long term effects possible as this is not a long term fix, what you are doing here is borrowing time before having to replace the LED strips. This video was put out because no replacement LED strips were available at the time.
However replacement LEDs have been manufactured recently and are now available. I have a video you can watch that is linked at the end of this video that shows the replacement process of the LED strips.
@@NicksTVRepair Ok. Thanks a lot for the reply :) I just wanted to be sure that, while I wait for the LED strip to come, it would not damage other components. But I guess that this temporal fix would last for a month. Thanks :)
Hello Nick 👍
My Sony 65x8505c, also does the “loop”.
Do you happen to know, which mainboards that are compatible to my Sony model?

The model you have is a European model, I am not familiar with those and compatibility with them
Hello Nick
Thanks for your quick reply 👍👍👍

I fixed my TV this way. After replacing the power supply board and the led driver board was still having the power loop and the 6 red blinks. Tried your hack and it worked. Now I have image issue, that could be main board bad or I didn't connect the ribbon cables properly. Tomorrow will check again
If you have issues with the light strobing then it means you have to replace your LED strips. Here is a video on how to do that linked below:
ruclips.net/video/S5V0hRjH7TA/видео.html
Hi NIck, I notice that when I did the quick fix there were dark shadows on the bottom of the tv and then they disappeared. Is that a normal thing or not.
And thanks for tip also.
That is because this is not a repair, this is to force the TV to stay on even thought the LEDs are starting to go out. So what you are seeing is just the LED's starting to go out.
The real repair would be to replace the strips.
did this and my BL ERR i make sure its line 1 pin 8. i remove it and the wire is pushing massive voltage. grounding it melted a post. triple checked again and again, its the correct pin. any thoughts? Tv turns on, backlight hdr everything works, no bright or dark spots. Then suddenly turns off, blinks 6 red, turns right back on. tv is the kd x8 65x8577g
If this is happening then you are not doing it right. Either you are not locating the correct BL-ERR pin or you are counting from the Top VS bottom for pin 8 and maybe you are grounding out a 12 line. Even pins are on the row located further away from the circuit board and the odd ones are located closest to the board. If you have the TV standing up with the back cover removed and you are looking at the power supply in the set pin 1 and 2 are at the top. So looking at the left side of the connector count down 4 rows for pin 8. If this doesn't make 110% sense, then don't do it as you may just damage your set further. Maybe email me a picture of what you are doing with arrows or circles or even a short video to the email in the video description.
I would say to do the proper repair which is to replace the LED but you also run the risk of cracking the screen, so just be aware you are doing this at your own risk.
Hi Nick, I have the same problem (4 times blink) with a Sony 55X900E.
But internal boards are differents so I can't use your fix.
Any hints for the Sony 55X900E ?
Thanks.
For the 900E models, I wouldn't' recommend that same fix since for your model the LED strips are available and are going to be much easier to replace/service than the one I have in the video.
I recommend buying from Shopjimmy, they are one of the more reliable sellers of parts
@@NicksTVRepair hi nick I also have an x900e and currently have the 4 blinks problem. I don't have enough money to get the led strips. Would your video be compatible to fixing my situation? Thanks
My Sony XBR-75x900f is doing the same. How long do you think this fix will last or should I just change all of the led's. Thanks for any info!!!
This will not fix your 900F sony TV. This fix only works on the 900C models. You will have to replace your LED strips in order to fix your set.
Did you managed to fix your TV?
I have a Sony xbr-49x900E that is blinking 4 times. can you tell me which pin is the error pin that I need to ground. I have pin 1 white, 2-3 gry, 4-7 blank and 8-10 gry. Any help would be great. This one lasted 4 years and for 1200 not a good deal. Thanks
I don't know the pin out for your TV set since the power supply doesn't have it labeled. Even if it was properly labeled I don't think it would work that well. This model in the video has edge lit strips that can throw this error even when they aren't bad or if they are on their way but still work. This trick doesn't work that well for other models.
This model has very hard to obtain LED strips and they are very expensive if you are able to find them. For your set however the LED's are readily available.
I recommend you get the LED's replaced.

@@NicksTVRepair Quick question. There are two connector strips on the top of the T-con board that come from the main board. when I disconnect the right cable ribbon, the screen goes through a continual color test display, different colors and strips, and there is music playing with it. No blinking red lights. It just keeps cycling through. When I disconnect left ribbon, it gives the 4 blinking lights of death. Do you still recommend replacing the LED strips or could be something with the main board. Is there an easy way to test the LED strip to make sure without tearing the whole thing apart. Just want to make sure before I buy the LED replacements. thanks...
It worked!!! Thank you so much for your video #subscribed
You're welcome!
@@NicksTVRepair as soon as we put a movie on we could see the flickering of the LEDs, but this morning it worked perfectly. Strange lol
Hi Nick..i own a Sony A8F (Oled TV) for around 4 years. Theres 6 red flashes that occurs occasionaly and i hv to soft reboot everytime to make it go away so i cld watch the TV. Theres no apparent defects on the picture once its on.
Ive accessed the service mode & it showed some codes on backlight error. Pressing 8 & 0 wld make the error codes go away and the flashes comes back again a few days later.
My question is can your method work on my OLED Tv? I just want the red flashes to go away for good. Changing the whole screen panel is not an option because of the high price. My warranty has ended. Also, the service mode indicated backlight error but is it true OLED TV doesnt use backlight? Pls give me your thoughts on this. Thanks
Yes this would work on the OLED TV.
I have the XBR-55X850C with 6 blinks. Is the connection on the power board or the BMFL? I took pictures of both boards but the pin-outs look different from this video. I want to know if I need to send in the BMFL board for repair or if I can just trick it to get some extra life out of it. I already created and account on your repair site for when it finally expires.
Nevermind, I found it for my 850C model. BL-ERR is top pin 4 > reroute to > bottom pin 23 GND. If anyone is trying this, the pin-out ID label is near the connector.
did it work? This fix is not supposed to work for any other TV's other than the 900C.
For the other TVs it will stop the error code from triggering but the backlight fault will still be present. The reason it works with this model however is because it seems this model triggers that fault even if the fault is not truly present. As if it is hyper sensitive.
@@JakkiPithanks for posting the info!
Hello nick! I have a xbr-55x850c. Curious as to what pin this might be. I can send pics as I have the back off right now
This trick won't work with the 850C. For the 850C you will need to replace the LED strips in the set to get it working again.
Hey Nick! First off, thank you for these type of explanations. Right to repair or extend the life of electronics should always be made available for the masses so I appreciate your tutorials here. I have an XBR-65X800G model with 6 red blinks appearing. I called the closest Sony authorized repair dealer and was told that it's a panel failure, of which, Sony no longer manufactures the necessary part. Would this tutorial help resurrect my television the same way as the X900C? Also, by panel, do they mean the LEDs or is there another component added to this model that older models do not have? Trying to gauge if this is truly a goner in repair or some life left in it. Thanks a ton!
Literally,
You can give it a try but I don't think it will work because those strips fail differently. When someone says failed panel that can be a failure of the screen, or the backlight. Both are included in the panel. Sony does not do LED replacements, however you can get replacements from third party manufacturers. I would recommend going to shopjimmy.com they have tons of replacement LED strips available and I bet they have some for your model as well. They also are on RUclips and show how to do the installs. I recommend them highly.
Should I do the same thing to my Sony KD65XE9005 ? Because it’s 4times blinking
You don't have a North American model so I don't know exactly what the equivalent is exactly. But unless its the same exact set it probably won't work. You will have to replace the LEDs most likely to fix it. You can check this video out for LED replacments

Hey brother, im having trouble reading witch wire is the bl_err anychance i can ask for some help
I am sorry but if you can't identify the wire from the legend then you will have the same issue identifying the wire within the connector which means I can't help you without being there in person to do it for you. You need to use a magnifier or have someone that is there physically with you to help you.
Is this possible to do on a XBR-55X850D? I have opened the back of the tv and am not seeing the same type of circuit board.
This is something you can do on the LED driver/sub PSB.
@@NicksTVRepair I have a xbr-55x930d. Can you instruct how to do this on the led board? Thanks!
Hi Nick, will this work on an XBR-85X900F? I found the BL_ERR wire but there are 2 of them?
There should be only 1 of them. The 2 different ones you found are most likely the same line except you are looking at it when it connects from one board to another. It's all the same wire just both ends of it. If you ground the line at 1 of those two points, you will have grounded the entire line. Doesn't matter which since they are the same.
Did it work for you. I tried 75in no change
Question: my XBR-65X850D had the six red blinks show up. The tv went blank and I powered it down. Then I powered it back up and the TV was fine for a few hours. Then it did the same blink and turned off.
So I did this fix, which bypasses they error. But it doesn’t bypass the left side of the screen and that side goes blank. The right side stays lit up.
So I then went into the TVs settings and turned down the brightness to like 5. And I turned the black to like 2. Now both sides of my tv work fine. Neither side goes black.
So question! 😁 what could be my next move here. I want to point out that on the powerboard, there are two sets of four small squares located where the backlight wiring connects to the powerboard. On the board and at the location of two of the squares the board looks a little burnt. Let’s say more brownish than around the other black squares.
So what should I do next. Again, backlight now only goes out when I turn up the brightness.
If you wanted to really fix the set, you would need to replace the LED strips.
@@NicksTVRepair do you sell the strips? Or know where I can buy them?
Thanks! 👍🏽
@@mwredfern THe only place I"ve found is ebay. Places like Shopjimmy show out of stock.
does this also work for kdl 55w805c? if so, which cable please
Yes, the pin output may be a bit different thought.
Thanks for the video, is there an option for an aftermarket led replacement?
I'd like to repair it properly, if you offer them for sale I'd like to purchase them from you guys.
Hello Lupe,
We unfortunately do not have them for sale nor do we have a supplier. If you are able to find a supplier for them, please send us a PM as we would be highly interested. Currently we are only able to find the occasional used strip on eBay for about $100 per strip, but you will want to replace all 3 strips when you do this if you can. Only problem is that the strips at $100 a piece are used, not new, so you never know what you might get. If you can, I recommend just reflowing the strips as the LED's themselves rarely go out, instead the solder joints crack and cause the failure.

No this only works for the 900C model that I am doing this to in the video. It works both for the 55" and 65" 900C versions.
@@NicksTVRepair Hi Nick! so I managed to find the white connection (bl_error) removed it from the PSU CN6401 connector (Pin 1) and moved it to pin 4 (GND). However, the issue still persists. The sony technician said it was most probably the panel/screen. Do you think it is repairable? Just to note that when the TV starts.. the LED Driver board lights green and then flashes red. Thank you
No this only works for the 900C model that I am doing this to in the video. It works both for the 55" and 65" 900C versions.
That was my last comment and I urge you to read it again. So it 100% makes sense that this didn't work for you. Because you don't have the 900C model. Your 4-blink code is not a panel fault, it's an LED failure. You can't fix the LEDs with this because again you don't have a 900C model TV.
So to fix it you have to replace your LED strips. Also, you need to make sure you talk to a new tech, who ever told you that a 4-blink code is a screen fault based on your model number has no idea what they are talking about or they were not provided the correct details.
Hi Nick, great video. I did this and it worked. The tv doesn’t shut off anymore. But now the bottom of the screen where the LEDs are keeps flashing at random spots. Does that mean the strip needs to be completely replaced?
Hello Carlos,
Yes unfortunately this means that the LED's have failed to the point where they will indeed need to be replaced or serviced.
@@NicksTVRepair Hi Nick. I´ve done this too, and it worked. But one led seems to be dead, there´s a dark spot at the bottom of the screen. And sometimes all led´s are flashing at random. Is it possible to change out the one failed led? And if so, can you go through the process of doing this?
Good morning Nik
I have xbr85x900h I have 4 red blinks
I bought a crack screen same model and change all the board and still 4 red blinks after the sony logo.
Any idea on what my be the problem.
I will appreciate your help 🙏
4 blinks will be an indication of failed LEDs. The easiest way to resolve the issue would be to not fix your TV, but instead swap your good screen onto the TV you purchased with a bad screen. This would be easier than if you tried to remove the LED's from the donor TV and put into your set.
@@NicksTVRepair ok great advice
Thanks very much for your help....
👍👍👍
HI, will this work with Sony 65X950G too? there is Sony and android logo at start up but then stuck with 4 red blinking light ? I have been doing some research with this model, most people have replaced all the board and at the end seems to be the LED back light issue.
ok here is what I got. as mentioned the tv turns on, Sony and android logo then 4 red flash led at the front of the tv but 3 red flash on the LED board. also there is no power to the BL_ERR pin. is that mean the 4 red flash led is not from the BL error? main board issue? what is 3 flash red led from the LED driver board? thanks
You will need to replace your LED strips in order to fix this issue.
@@NicksTVRepair hi nick, you were right. I was able to ground another BL_err trace and tv works. and I can see a tiny dark spot near the centre. I guess 1 or 2 led backlight burnt out.
for future project I guess.
Nick Hello. I have a Sony 75 xbr850E. Bought it in 2018. Just got the 6 blinking red lights. Will this work on my model? Do you have a way to confirm for me what pin I would be grounding out in my model? I can't seem to find that info anywhere🤦♂️
Sorry this only really works on the 900C models.
@@NicksTVRepair I actually found another vid confirming the 4th wire in from the right was the correct choice and it worked fine upon grounding it out! Upon inspecting it when the back panel was off tho I did see one pretty darkened portion where the backlights connect to the secondary board. Don't know how much life there is left because it's darker now on the left side since it's back on. But at least it may give me time to find the parts b4 it goes out completely. Thanks for getting back🍻 God bless
@@NBAwasBetterInThesands Hi. I have similar issue with xbr 75X940C Which pin did you ground and on what board? Thanks.
Tore x900c down to bare bones and started tv, backlights came on and ALL stayed on indefinitely, seemingly same brightness, when I tried the BL err bypass the backlights surged, back and forth, across the bottom but tv stayed on, this all started with a 4 blink red code, seems like BLs are good, could BL still be bad/going bad? Seems like the longer the tv is off the longer it runs but once it goes to 4 blink red code it goes there again and again with restarts but with power off, for days, it comes back on for half 45 minutes ish, with no visible screen issues. Any other ideas, can I try to micro resolder the led strips solder points, again all lights are on? I could see it being an backlight (BL) failure if evident but not seeing a BL issue. Got the Tv for free and hoping dad in law can use it for a bit. Thanks for your helpful videos.
Thinking power supply actually?
If doing the BL-ERR to GND allows the backlight to turn on but you see it turn on and off almost like a strobe light, then it means your LED's have failed to the point where they will need to be replaced or repaired.
You can try resoldering the LED's there are videos of people doing that. It is however a very time consuming process and you will need to have descent skills with a soldering iron to pull it off.
@@NicksTVRepair Thank you
I have a Sony XBR-55A9G that turns on and immediately shuts off and I hear a clicking sound in the back when it turns off and the red LED blinks 4 times. I've opened the back but the board in this video a different than mine, I don't have a separate LED power board. Is there another way to fix the 4 blinks error on my tv?
You may not have a separate LED driver board but you still have an LED driver circuit which most likely is built into your power supply. So what that means is that one of the connectors on the power supply will still have a BL_ERR pin which will need to be shorted to ground. You will need to look at the legend carefully on your board, and identify the correct wire. Once you have done so you can follow the same steps and ground it out.
This may not always work, if the error code is no longer there but you don't have any picture on screen, it could be due to the backlights having failed in a way that requires them to be replaced. This trick usually works with edge lit tvs more so than back lite tvs.
@@NicksTVRepair I found the BL_Error pin, it goes from the power board to the main board. Which side needs to be grounded? The pin that goes into the main board or the one that goes into the power supply board? What if after grounding the error is still there, can it be a power board issue? Thanks
Take the BL_ERR pin on the power supply connector and put it in the to an available GND slot.
@@NicksTVRepair thanks for the reply. I did not have a GND slot on that connector but I grounded to one of the Power board screws but still gives me the error.
Here is a video of the cl8cking noise that my power board is making when turning on and off.

Can you help me fix a XBR55800E? I have 6 blinking lights.It turns on but if I try to watch netflix it goes off. I am a woman so don't know much about TVs.
Hello Kool Kitties,
6 blinks is an issue related to backlight failure. If you are to properly get the set fixed you need to replace the backlight. This is something I recommend bringing in to a shop for repair.
However you may be able to squeeze a bit more life out of the set simply by turning down the backlight setting on your TV set.
Go into the picture menu and find the backlight setting. It might be under advanced settings if you don't see it regular picture menu. Turn that down a bit and that should avoid triggering the blink code.
What’s up Nick I have 6 blinks on a Xbr75x800h what’s my best option… led strips or replacing the boards??
6 blinks is the LED strips. They will need to be replaced for that model
thanks man appreciate the help/advice
I called another tv repair shop and explained then asked if they replace the leds and he told me it wasn’t my leds it’s my panel so now i’m confused as to which route to take now. Would love your input on the situation. Tv is just over a yr old blinks 6 times and the screen is black
i have the same problem, 4 blinks code, my TV IS XBR-55X900H i can fix the same?
No this is specific to the 900C series
I have a Sony sony kd-65xe9005 and after switching it on it runs for 15 seconds and then it goes off and flashes red 4 times. I don't know what to do to fix it. I do not have much money
In order to fix that model you will need to replace the LED strips. There is no quick fix with that one.
Hi, I do this but my tv now can play sound but with no image, my backlight turns on at the first 2 seconds
Hello Omar,
This means your backlight is to damaged and the only way to fix it would be to either repair or replace your LED strips entirely. Unfortunately I don't have a video showing how to do that.
Which wire on Sony 70w830b.
It's like mine is double wire on each roll
Each TV is different and this may not work for you set. You would need to look at the legend on your power supply board and located the BL_ERR line and ground it out like I did in the video.
@@NicksTVRepair OMG it worked
For Sony 70w830b is the gray wire
I cut it and grounded the wire to the tv panel and tv stayed on
Great video and sound
I paid $30.00 for 70 inch tv on Craigslist
Thanks a million
changed backlights all light up put all together comes on but still goes back top 4 blink error is there a reset procedure these sonys drive me nuts lol xbr49x950h Thanks from Joe!
For hte 950H its possible you may have an issue with your driver board as well.
@@NicksTVRepair the LD board with the ribbon cables correct
Oh never mind I just looked up your model and it doesn't have the driver board that we see failures with. Sorry your model has an LD board that doesn't actually ever go bad. At least I have never seen or heard of any fellow techs having to replace that one for this model.
It's going to be the LED strips that need replacement for sure
hello nick.. i got XBR-65X900C and there's a sound but no picture. need help!.
Gavin,
What have you done so far for troubleshooting?
@@NicksTVRepair I replaced the main broad. The old one won’t power on.
@@mr.catman7939 firmware update
Hi Nick, will this work on the kd65a1?
Maybe, but probably not. You would have to give it a try to know for sure but I have a feeling you will need to do a full LED strip replacement. The reason this is more viable with this set is because it is edge lit, and no LED strips were available at the time.
If you can change out the strips, then I recommend doing so as it is the better way and correct way to fix your set.
Would this be the same for xbr65 900E
No unfortunately this is very specific to this model TV. You can try with the 900E but I don't think it will work.
The reason it is being done for this model is because LED's were never avaialble until recently. If the strips are available it is always better to replace them.
I have a xbr 65a9g, will it work as well?
No unfortunately that will not work with that model. This trick only works for the 900C
65X900E here
A similar issue, it will stay up for 20-30 seconds, loads Android TV interface and then shut down with 4 red blinking lights
Any help please?
This trick only works with the 900C. For the 900E you have to replace the LED strips to fix it.
Do you have a video on how to change the LED strips on the 900E model?
Try the hard reset. I had a Sony 900e that did that once and the software update got corrupted. And the main board was giving false error code and shutting down with the 4 blinks. Hard reset fixed that tv. But that was a rare case. But it was a cheap fix for the customer. The newer Sonys been having software issue when updating sometimes.
I have an XBR-70X850B with a 4 red light blink LD_ERR code. Replaced LD driver board and still same issue. I just disconnected the LD_ERR cable from the power supply board to the LD board and grounded it. It's been 20 minutes and so-far-so-good...thanks,...BTW, I tried grounding the BL_ERR cable first and that did not work...let's see now..
Huber, that is very valuable information, great find! I will add it in the video description in case anyone has the same issue.
@@NicksTVRepair Yes, and 5 days later, TV still working....much appreciated!
@@NicksTVRepair BTW, the way I knew to ground the LD_ERR pin is because when I went into the self test diagnostic history screen, it showed this as the error. The way to get to this screen is to press on your remote: , then , then , then , then , then again, pressing each button within one second of one another.
I accidentally ripped my error cable trying to remove it from the clamps. Am I screwed?
That's good to know. The Sonys where always over sensitive on monitoring the current load on the LED drive.
I did it!!! Thank you very much!!! You saved my tv and my money
Nice! That's great news. It doesn't work for everyone but it should work for most people. It mostly depends on the severity of the failure.
How about for the XBR-75X850C? The service manual also mentions the BL_ERR signal for the six blink problem.
Check a voltage of
BL_ERR_DET.
Check point is
JL9007
or
23pin of CN9000
on B*Board
Wondering if the same procedure works of disconnecting the BR_ERR_DET signal from the LED strip.
Service manual is here:

ruclips.net/video/kbk2SJkmtnM/видео.html
Yes the same procedure would work, however the pin outs are going to be a bit different but the concept is the same.
So which wire am I removing for a 55x850c? This video different wire? Test showed no errors. I have the 6 blinking red lights.
Hello do I do it on a Sony xbr-75x900f
This will only work on the models mentioned in the video, it won't work with other models.
Will this work on an oled tv? XBR-55A8H
It will not.
This is only for the 2015 model numbers that end with 900C.
hello. i have a Sony KD-55XG9505 from 2019 android TV, it dont start i have 4 times red led blink. but for a few seconds tv tries to start and the image is looking good. someone was tellin me, if i bypass the backlight error wire, the tv could heat and start an inside fire. tell me if its true . thanks. basiclly this is a protection, how will be behave if i bypass this protection? many thanks PS. i've changed all the circuits inside, mainboard, power source, and led driver :) it does the same, people says is backlight leds, but like i said before the image is corect (for seconds, then enter in error mode 4 blinks)
What I am doing with the 2015 Sony 900C model is only for the 2015 900C models. You do not have a 900C model and thus this won't work for it.
As for the catching the TV on fire, yeah that is entirely possible because you don't have the 900C model. But also it's extremely unlikely.
But more importantly there is no reason to do this because it won't work for your set, you need to replace the LED strips, that is the only way you will fix your TV.
This sounds like the same issue I have my picture and backlight look fine for like anything between 5sec-5min then the TV auto powers off and gives me 4 blink in red
@@Bu5H84 so did you find anything? someone said to me, if a led is burn you dont see on the screen because the rest are so bright, but the system gives error, because the voltage is different with one led burn
@@Bu5H84 by the way, i've changed mainboard, power board and led driver board and it does the same 😂
I too have changed the Tcon board LD driver board and still the same issue, I'm now going to replace the two PSU, if that doesn't work I'm going to try replace the LED's
I have a Sony 49x900f and it turns on then turns off and blinks 4 times the bl error pin it at 0. What should I do
4 blinks is a backlight failure. You will need to replace your LED strips most likely.
On the XBR-49X900F BL_error is pin 1 which is the white wire right? (It has no voltage going through it does that mean error). Sorry for the question I'm just a bit lost since the TV does turn on and say Sony and they does the android logo with the animation before crashing.
@@user-wf2ek8hz8gI have the same model and same problem
Does this apply to the 850D model also?
yes, but the 850D models may have a different pinout meaning the BL-ERR pin may not be in the exact same location. You should be able to find it based on the legend printed on the board itself. Once you have located it, simply ground it.
I have. 930D model and cannot find the bl_err pin. There is not a legend on the board. We’re you ever able to locate the pin to ground? Thank you so much
Any success on an a80j and/or a a8h?
Haven't had a chance to mess around much with those newer models yet.

If you cannot make a video, please give advice on how I can obtain a labeled diagram of my television. Sony, obviously, is worse than useless when it comes to helping. Factory reset was not successful.
This "quick fix" does not work on your model. To repair a 4 and 6 blink code on your TV, you will need to replace the LED strips from your set.
@@NicksTVRepair Please, help me save 2,000 dollars and tell me where I can find this information. I can do anything if I have instructions. Nothing inside the tv is even labeled. Can you do a video? Where are you even located, maybe I could just bring it to you. But seriously, this was Sony's most popular tv for a long time, high end for 2019-2020.

@@ceceliaburnett1796did you fix it? I have the same issue on xbr49x950h… 4 blinks
Will this work on xbr-55x850c ?
Yes this will also work on the model, however since the power supply board is a bit different, instead of removing the BL-ERR pin 2 and grounding it to pin 9 your model will have BL-ERR as pin number 8 and the ground pin that's best to use would be 22. I believe both will be on the top row, BL_ERR as the 4th pin on the top row when counting from the top of the connector down and the grounding pin will also be the top row and pin 11 if you count straight down. I hope I am not being confsuing when stating they are pin 8 and 22 but then stating they are pin 4 and 11. I am saying 4 and 11 if we exclude the bottom row and you just count down the top row.
We will be making a folllow up video so it's easier to follow than this explanation. Should have the video up in the next day or two.
