Re: Samsung 42" Plasma PN42C450B1D

I have the same TV with the exact same issue. I see where you guys identified the X main and they grey power cord to unplug. Could you please identify where the Y main is?

I tested with X main unplugged and same issue (clicks but doesn't turn on at all and just gives up). I will test with both unplugged next, and based on what I've read above, if I hear the Samsung chime then I need to replace both boards?

Thanks much.

Cheers
