Pioneer PDP 503 Problem
 

I have a Pioneer PDP-503PU that shows this display without the media
box attached. It shuts down after about 1 second of this display.
For those who don't want to look at the images it's a green screen
sort of divided up into thirds with the top being green, middle is
white and bottom green again. It has an image of a television channel
on it that is not clear, almost like the scan rate is wrong. My
suspicions are a signal module, but I'm not convinced.

What do you think could be at issue here, and fyi it does have the new
power supply with the orange dot.
