I have a Sanyo HDTV quality, and about 6 months ago while I was watching TV about half of the screen had a green tint to it and the other half had normal color. The next day the picture was okay--all color back to normal. This has happened several times now, and I'm wondering if it could be a problem with the cable or if it's with my television. Has anyone ever experienced this--or know what might be causing it.

You had better get it settled before your warranty runs out. Call Sanyo, they will have a hot line and its probably in your warranty package.
