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.

@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.

I'm having the same issue with my OLED 65" TV. Only 6 mos old. Intermittent spontaneous powering down for the last 3 days. Now it won't turn on at all. I've tried resetting - nothing works. Checked all the connections. I'm going to schedule it for warranty repair thru LG. Disappointing! Sorry I didn't have an answer.....
