Report "I have a Gateway DLP56TV 56 in. Rear Projection Television. I have been able to work out most problems. I have replaced bulbs... I had the humming noise and replaced the color wheel. I've had the front off and cleaned the mirrors. But now I'm having another problem. It happens only in HD. It can't seem to handle bright white screens. It will get a horizontal static whenever a completely or mostly white screen shows up. I can almost live with that, but after a couple of times, it looses color. When it comes back after going haywire, everything is darker. It is getting worse. It does it all the time. I've played with the brightness settings and that doesn't help. It just makes the darkness kind of grayer and washed out. It only does it in HD. If we're watching a non-HD station it is fine. Does anyone have any ideas? Where can I get parts for this? Other than the color wheel or bulbs. I can find them. Thanks, Dave"
