The gray bar sounds like a light tunnel collapsing. This has been very common in Samsung DLPs. I have heard of some consumers getting some manner of accomodation on the repair from Samsung. You need to get your local Samsung Authorized servicer to evaluate it. Verify beforehand that they are familiar with the light tunnel problem and see what they know about any warranty accomodation that Samsung might be providing. Once you get an estimate, call Samsung customer relations and see what you can get out of them.

The sound problem sounds unrelated. Does it happen on all sources?

That sounds like something else in addition to the light tunnel. First guess would be a digital board, but you need some skilled troubleshooting for that. Get your set to a Samsung servicer.
