It just started happening. Sometims it goes to all green and I have to power down, once it went to all yellow but for the most part I have a green stripe, with a few other colors, across 20 percent of my screen. The fist thing I noticed was off was when I powered up I no longer got the countdown to the image, now it's just a blue screen with the Optoma image. Tried switched from SVideo to RGB but it made no difference. Tried a reset but I'm not sure I did it right. Any ideas would be really appreciated! Best, Jb
