So the t con board was the issues? My lg oled65c9PUA is doing the same thing. It all started when I tried to play a game on the Nintendo switch. Selected the game and then the screen flashed green and it turned off. I power light is red but it won’t turn on. I hear a click and nothing. Tried a new power supply and still the same issue. Tv is out of warranty
OLED55b7v - i have the almost same problem, some times it comes on just shortly, but mostly just click noise - led blink - but the tv does not turn on. I bougt a new power supply board, but i did not solve the problem. Then i can across this post, so i hop a new T-con board may solve the problem....
@sgade39979 how many times does your power LED blink?

@rekka not sure what you are referring to by "LG oled". I suppose you are inquiring about a TV. We would need to get the proper make and model number to try and help you out. You most likely have not much left to buy other than the T-con board. Not turning on is very seldom (I've never seen it) a t-con board issue. So give us a better idea of make and model and let's see if we can figure this out.

When ever I power my OLED TV with Model No: 55EG910T-TB and Serial No: 609KCJZ8E948, the red light power indicator below the front of the TV will be on, indicating there is now power on the TV, once I press the ON button on the remote control the TV will be processing to come up but suddenly it will go back to power mode, like the screen going off back to power mode were only the red power indicator light will be on at the bottom the TV, please help me out what is the solution?

I change the main board and the t- con and still had the same problem.

Dan G and @ballhead could be the power board as well as a few othre things. You would have to take the back of and take a look at the boards. Check for obvious damage and you may need to measure some of the voltages on your power board etc.
