Philips 55PFL3907/F7 Sound and Backlight, No Video

Did you ever fix your 55" philips tv? I have one doing the same thing. I have also changed the "frc" board with no luck. I also have good input signals to the frc board from the main board, but no signals out of the frc board.
I think that I got a bad frc board from ebay. Did you ever fix yours?
Thanks,
Dan
