HELP...Picture trouble on a Zenith Z60Z83D8 projection tv

[Guest]

Hello,

Im hoping someone can help me with a little advise...My projection tv is having a problem... Periodically the picture will slowly fade to black, you than turn the tv off for a minute or so and it will fade back to a picture of normal color. While it fades i still have sound and i can change the channel and if i shine a light at it i can actally see the picture but very dark. It is also hooked to a DVR box from the cable company and I think it has something to do with the box but the boyfriend says its not. Can someone please help me with some suggestions. I had a service manual but after 3 days of searching i can no longer find it.

Model# Z60Z83D8
Manufactured 1997

Hook a dvd player up and see if it happens on that source. If it does, it's the tv, if not, it's the cable box.
