Re: Samsung 42" Plasma PN42C450B1D

I just found a 4th X Main board but I'm hoping someone can offer advice before swapping yet another likely dead board :/

Re: Samsung 42" Plasma PN42C450B1D

Bumping this thread since I'm also trying to fix this old TV after just fixing a buddies Vizio. I've fixed blown cap LCD Samsung's in the past but this plasma seems a different beast. I've got three X Main LJ41/LJ92 boards, the one currently installed worked for a while like a year ago, this weekend I played with it again...no picture, changing sources does nothing (a YouTube video suggested it), green light flashes on the little board in the middle, red light comes on and I get the startup sound.

It's been so long I forgot...
