My friend is having problems with his Panasonic TH-50 PHD7UY plasma, (which he bought from me last year). What is happening is he is getting a very slowly scrolling interference pattern rolling up the screen, taking about 5 seconds to complete the trip, then repeating. The pattern looks like 1" square blocks. The panel was recently moved (carefully, I was there), but he can't say whether it was happening before the move, due to circumstances. He tried several different sources (Cable, DVD, Tivo) through all the interfaces (HDMI, Component and S-Video) and the same pattern appears. It also appears if there is no source and you open a menu. I imagine it is there on a black screen, just impossible to see. We also hooked it up to a power conditoner to make sure it's not the line. This doesn't appear on any other TV in the house.

Here is a video of the pattern (albeit a crappy one). Look about 5 seconds in when he zooms into the wood background. You will see what looks like a string of blocks roll up from the bottom of the screen.
Any ideas?
