As soon as its plugged in theres 24v going to the backlight and 12v to the main board.
I think the issue is with the main board.

So i got a Kogan 42" tv for free a while ago that does not turn on and im trying to repair it for myself but had no luck so far.

- Once its plugged in, the red standby led comes on for about 2 seconds then turns green with out me pressing any buttons. The tv remains off.

- All caps look new on the supply board, no bulging or leaks. I changed a few of them with Rubycon's anyway, no difference.

- After leaving the tv unplugged for a few days it did turn on and remained on for hours until i turned it off which then it refused to turn back on.
