Picked up a dead RCA Plasma

[walterbeers]

Got a hold of a 1 1/2 year old RCA plasma 42", model 42PA30RQ, which was made by samsung. Was told it was working fine then all of a sudden went dead. Power light comes on, (Red in off position, Blue when powered up), remote works, (makes relays click, and power light turn blue), but no light on the screen and no sound. Power supply board remains cool. All Caps look OK. Ordered a power supply board, just hope it works. when I get it. Any other ideas guys.
