Dude, your video saved me from having to replace backlights or replace the TV entirely. Really appreciate this! Thank you so much for sharing what you discovered here.

This began happening on my kd60x690e last week. Here's what I can confirm. A few yrs ago I had a device plugged into hdmi 3 arc port and the device dropped and damaged the hdmi port. It still worked but was hit or miss. Last week I had a device plugged into that port because hdmi 1 and 2 were already in use. After I unplugged the device from the damaged port, that's when I got the 6 blinking red lights. TV was dead dead. Last night I wiggled the damaged hdmi port around....and boom....TV turned on. Related to hdmi port.

I had the same problem on KD55x8509cbu. Did the usual , factory reset ( vol - , power together) etc nothing worked. So decided to open the back , straight forward removing screws which were marked. Disconnected the connector and reconnected ( the one other videos shows to snip the cable on ???) and tested TV and it started working and it wasn't factory reset !. Thks your video inspired me to have a go.

I have had the same issue over the past couple of years. Methods I have tried in the past with varied results (sometimes they work and sometimes they don't) 1. Blow air in the back, 2. Hit the back of the TV, 3. Push the power button on the back of the TV then push and hold the up arrow on the TV remote and also press and hold the TV power button on the TV (This resets the TV). But this latest time that the TV stopped working none of these methods seemed to work for me. Then I came across this video. I bought a Multimeter and did the same thing @RepairMan did and it powered on the first try. Thanks

KDL-65W850C..I am facing the same issue. What is wrong with you, Sony? Can you help out?

I've Sony 40R452A bought 8 yrs back. It was working fine for 8 yrs without any issues. Just few months back I bought Amazon fire stick. From here the problem starts as you mentioned in the earlier post. I'm getting 6 times led blink then screen goes off. Tried resetting the TV, used jumper but issue continues. Then I dismantled the TV and checked LED strips. LEDs are good and all r working fine. I could have soldered the led strip joints with a seperate wire. Can you pls help to solve this issue.

Great video. I replaced the backlight led's but now getting sound but no video - any ideas ? Connectors are all good. Thank you!!

One interesting thing I noticed is that the issue only happens when I have a device (Fire Stick, Roku, etc.) connected to the HDMI port and I leave it connected and powered on after I turn off the TV. After a couple of hours of the TV being off and then trying to start it will trigger the issue. Since I noticed that, I have been disconnecting the Fire Stick and the issue hasn't appeared anymore. Now it only happens when I forget to disconnect the Fire Stick every time I turn off the TV. So this issue seems like some glitch in SONY TVs where you can't leave a powered on streaming device connected to the HDMI port for a long period while the TV is off. I am leaning more towards a main board glitch than a power supply board issue.

thanks, having same problem, are you able to fix it, first few days when i hit back side it did turn on, and after few days same problem, now its no turn on, seems same issue, let me know any one able to fix this issue

i have the same problem, have you fixed it?

My tv has the same yours problem. Did you solve your tv? How? Thank you

Can someone tell me which wire is the BLL-ERR pin Sony XBR-75X850F

Any update? did you end up replacing the LED lights?

Could it be down to a bad earth problem ?

nice camera work

I also have the same issue. When I use the LED backlight tester the voltage is about 136 volts and then the tv starts working and the led voltage goes to 160 volts. If you look on the PCB just below the LED connector in says the VLED voltage is 155 volts. You can also see it in your video. I am testing the TV with nothing connected to it other than the plug and tester.

I am also experiencing the same issue with this model. The light blinks 6 times and tv won’t turn on!

It worked for me as well. But did you get a chance to identify what actually caused this issue. And how did you fix the issue? Or are you still using the temporary solution.

can you help me fix it? How much to fix?

I'm a retired woman can I try to fix it myself ? what tool to use to turn on the T V . THANK YOU REPLE.

Set LED back lights lower than 100% output asap.

I have the same problem. On my TV I measure the the LED voltage at turn on, it is good but the LEDs do not light. This means it is the LEDs. I can hit the TV while in the turn on process and the LEDs start working. I think it's probably a bad solder joint on one of the LEDs. Your LED tester may hit it with a higher than normal voltage and that could jump the oxides of a bad solder joint, so it may not be the power supply, but a bad LED strip. Use a volt meter and measure the LED voltage as it starts up, if the voltage is there but the LEDs do not light then you have a bad LED or solder joint somewhere. Great TV when it works! Good luck and please let me know what you find. I may just replace my LED strips instead of trying to find the bad solder joint, I only want to tear it down once.

You Swiffer is also broke, I can see it because of all the dust on the tv! Lol!

Could be an arcing led

Oye mexicano lo podrías explicar en español?

For sure, it is LED backlight problem. NOT power supply. I replaced the full LED stripes. ok

It’s a problem with the LED backlights strips one led might have a shortage it’s best to replace them all .

Una pantalla de lo peor, desde que la compre no reproduce en mi Home Theater el sonido izquierdo, y el Optical no tiene volumen variable, y ahora este problema de las 6 luces rojas :(, nunca vuelvo a comprar una pantalla sony

One or more of the LEDs is weak or failing and power supply backlight controller needs to shutdown your tv for safety reasons.

Hey bro, thanks a lot, it worked to me, can you explain me why?

I GOT SAME PROBLEM

من وقت ما استلم البريطاني مدير لشركة سوني ...اصبحت الشركة زبالة ..والتفوق العالمي للصينيين وشركة LG الصناعة البريطانية الجيدة قبل 40 سنة..ولكن الان.. يبحثون عن تصنيع سيارات والكترونيات غير قابلة للاصلاح ...معناها ..التفكير الخبيث في آلية تصنيع الاعطال ..وليست الية تصنيع الجودة والمتانة

Try hard reset, unplug the tv then press the power and volume down button at the same time and plug the tv while holding the power and volume down button for 10 seconds

LED's are failing when power on. Replace the led strips

sorry cant look at this vid.. you are continuosly moving...
