I have a Samsung DLPTV, it is about 4-5 years old. About six months ago it started a noise, I traced it to the color wheel and replaced it in Feb. About two weeks ago the picture seems to have a lite negative appearance to it, almost like a double image, but not quite. Can someone tell me what I need to look for, if there is an adjustment or if I might have done something wrong in the light wheel replacement to cause this?
