Sony XBR-65x900c Led 4K TV, 4 red blinks. Easy Fix!

This is a Sony Edge-Lit 65 inch led television that powers on with only the Android boot-up sequence on the screen, then immediately shuts off and the indicator light on the bottom blinks Red 4 times.
This sony television model XBR-65X900C is NOT an OLED (Organic Light Emitting Diode) TV like I mentioned in the Video. It just looks like one from the unique and flat design. This also mainly includes the xbr55... model TV's. This is an edge lit LED television, and the led's are actually our problem. An Led problem is usually what cause the 4 blink code on Sony led televisions. We will bypass the led feedback ciruit and thus NOT repairing, but still solving our problem. The TV will stay on! TRUST ME!

[@720jlconner]

I'm attempting to fix my 55x900c but i have a question. The second board didn't have the same writing to the right of the plug. It had it on the first board. When you did it did you do it from the second board like he did or the first?

[@moisesvillar892]

Another satisfied customer. Easy video to follow with clear steps and guidance. This also solved the problem with my TV, the exact same model here. I was already looking at buying a newer 2023 model. Faster processor and UI. I was looking at a Sony BRAVIA XR65X93L open box item, so this saved me $1500.

What wires did you move to fix it ?

[@720jlconner]

@@HyperStrike the exact same in the video. On the 55x900c the boards look like their backwards from the video. But just cut the same cord he does in the same place and it should work. Been working for me ever since

[@These_go_to_eleven_1959]

I can confirm that simply putting the #2 wire over to slot #9 fixed the issue i was having with my Sony xbr900c 55". The set before would not go to the main screen it would just shit down and flash red 4 times. after switching the #2 wire the set is perfect now.

[@TheDannrockwell]

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

[@ericdossantos202]

[@TheDannrockwell]

@@ericdossantos202 we do have yellowing at the bottom f the screen now. Sometimes it flashes and is pretty bad, particularly when using closed caption at the bottom of the screen. A new TV is on our horizon but the “fix” allowed us some extra time.

OH THANK GOD!!!! it worked for me :D!!!! thank you for going the extra mile man and making this video, fyi instead of attaching the cable to the screw I just unplugged it and then plugged it into the 9th spot which showed to be ground for me! :D im so happy thank you!

[@superluvver3]

Thank you , you have saved the earth from so much landfill and done positive for peoples lives . I would recommend turning down the brightness on all led tv, makes the led last way longer ,as manufacturers purposly make these devices to fail. They also put the backlights under the lcd so you have to remove everything including the delicate glass, chances are you will crack the screen . Thank you .

[@ImranAli-rp4kd]

This is not recommended as all you have done is bypass the protection mode , more than likely this will cause further damage to the backlight circuit, you need to resolve the real problem which is fault leds

[@NeptuneSega]

@@ImranAli-rp4kd it won’t make it worse. It’s not going to provide more voltage to the other leds. It’s just a half baked “fix”

[@ImranAli-rp4kd]

@@NeptuneSega the voltage increases when leds fail , I repair TVs everyday and 9 times out of 10 the voltage goes higher and you run the risk of other leds failing and the backlight driver ic and the prism sheets might burn, sometimes the voltage won’t go higher but depends on how the led fails , sometimes it’s a short but sometimes it’s not , big problem is with Samsung TVs where there’s no protection mode and if a led fails then the tv continues to work and the leds run at higher voltage and hot and burn the prism sheets , that’s the good thing about Sony TVs , if there’s any fault the tv will shut down and go in protection mode and save the tv from further damage , it’s a good thing and not there to be bypassed

[@andrewtreinen837]

@@ImranAli-rp4kd I understand to repair properly but how can that be done if Sony discontinued led strips? I have been searching for over A year for new or used LED strips without any luck. Do you have any plugs for LED strips for A xbr75x910c? THX

I did not cut the #2 wire i simply lifted the tab and the wire pulled right out, then i just inserted it in the #9 ground position. Such a easy fix glad i did not throw the set away! three techs looked this set over and could not fix it!!! Now the set is as good as new!

[@SLIPKoRn2]

Do you see on the screen is something wrong with backlight ? after this fix

[@These_go_to_eleven_1959]

@@SLIPKoRn2 NO, the screen came on like it did when it was brand new and has been fine since. Apparently even though that "bad LED"sensor was causing my set to not turn on like it should there was nothing wrong to cause it? My set is perfectly fine now. It is a really stupid design IMHO. Luckily this wire swap fixed it and it wont happen again now.

Its not a permanent solution, its temporary. You are probably gonna have problem with it and you just giving it a few months or hell if you are lucky a year or so. You just stop the warning signal of something being wrong with the t.v. and thats it. Its like taking a pain pill getting rid of the alertness of pain and not getting the pain issue fix.

[@johnkowalski9260]

Hey man! Im a tech myself. I just took in the 55" version of this.XBR-55x900c. I thought I lucked out when I found your vid-same symptom-starts booting up and shuts down and 4 flashing red lights.Sounded to me just like backlight issue.Unplugged the LED driver board from the main board,and the TV stayed running.However,I checked every single backlight thru the ribbons with my LCD tester-and every single one tested perfect-I believe 7 volts.Put everything back together,fired it up-now no lights what so ever.Ran threw the voltages from the main to power board,now no BL_ON or TCON_ON voltage at all. Did the factory reset,unplugged everything but the main and power board,still no voltage for backlights or t-con at all.Tells me main board is done.One strange note,when I had everything plugged in,I WAS reading voltage off the LED driver board TO the backlights. 6.3 volts I believe. However,it was INVERTED! I couldnt believe my eyes! Yes I had the red on + and black on -,but I was reading NEGATIVE 6.3 volts! If it was POSITIVE,they would light up! Very strange! I also noted the PWR_ON to the power board was staying turned on even after shutting off the TV. Just freeking whacked LOL! I checked the BL_ERR and I didnt luck out,it was holding at 2.7 volts on or off.XBRs are nice sets,but wow-the main boards go wacky!

Hello. I have a question for the technician. I have this set but I have water or fluid stuck in the diffuser panels behind the lcd. How do you disassemble the actual panel itself? I have looked up many videos and I cannot see a good way to disassemble it. Is it all glued together or is there screws holding it together somewhere? I need to remove the lcd and get to the diffuser panels behind the lcd to clean and dry them. Any input would be very much appreicated
