I have a Panasonic th-42-pz80u that will not display any picture. I have already run through a couple tests to see what the problems is. First, there is no blink error code.

When I plug the TV in, the relay clicks, the F-STB-ON signal from the A board reads 3.2V for less than 15 seconds (it should be 15 seconds) and it shuts off. Almost as expected.

When A5 is disconnected, the picture on the screen goes from black but lit, to white.

The SC and SS boards have their green status indicators lit.

I have gone over <a>this service manual</a> and the Panasonic repair manual, but they only seem to help when there are blink codes. Does anyone here have suggestions?
