LG OLED65C7P turns on 10 sec goes off no display fix

[@pzhivulin]

Got the same problem after same TV automatically goes to sleep mode. I disconnected all cables and power, then in 5 minutes connected the power, automagically it started to work. But next day the same issue, pretty bored. Any advices? I could change the power board myself (former iPhone repairer). Do you have PSU board model #?

[@SOSfixElectronics]

you need to get a multimeter and check voltages,

[@pzhivulin]

@@SOSfixElectronics finally TV died. Going to check R7624 voltage according to service manual. How much it should be? BTW my TV plays audio, it’s discoverable on WiFi and works with remote, but no picture

You are very good skills repair

I appreciate your effort, sir. I have a OLED65B7A its flashing 3 times and turns off with a solid red light. I ordered and replaced T-CON, Mainboard, and PSU twice and facing the same issue. Do you think the panel itself has gone bad? Thanks in advance.

[@SOSfixElectronics]

did you use the multimeter to check the voltages? if all exist an stable, the tv will give less then 5 sec to test each voltage before it goes off i did see 3 blinks linked to the power supply board issue,

[@faisalkhalid9659]

@@SOSfixElectronics Correct i used the multimeter and followed your Volt chart on the PSU board. I have 2 PSU boards showing the same reading. Yes it gives less than 5 sec after pressing the power button and then the voltage drops.

@@faisalkhalid9659 good, check for short in 12v and 24v tcon input? check the tcon fuses? disconnect the screen flex cables one by one and turn on the tv each time and see if the tv will stay on longer or any change?

@@SOSfixElectronics Will do and let you know. Thanks for the responses

[@faisalkhalid9659]

@@SOSfixElectronics Fuses are good and i was unable to find any shorts on the T-CON. I disconnected the flex cables one by one and one at a time as well, the result was the red light kept on and not blinking. Also tried the same process after replacing another T-CON card.
