I had a local service replace the IC convergence chip on 2/25/09. When he powered up, it didn't reboot, so he replaced some caps in a module. After that the unit powered up fine and the picture looked great. But after watching TV for about 2 hours, the screen went to snow with horizontal lines scrolling from the bottom to the top. I talked to Direct TV for 45 minutes and decided the problem was the TV and not the satelite.
Any ideas about what is going on here?

OK, I have resolved the problem. The TV repair guy told me that my TV will not work on 720i or 720p frequencies (I hope I am saying this right). Anyway, at his suggestion, I tried a DVD and the picture was perfect, so the problem was that I was tuned to the wrong freq. I managed to get the Direct TV box back on 1080i and the picture is great. I don't understand why the Direct TV tech didn't know this. Seems as though this would be good info for them.
