I have a Mitsubishi model WS55411 projection tv. The colors are no longer converging together resulting in a blurred picture. The set worked fine until last week. The colors are all there they just appear to be "stacked" with red on top and green on bottom. The picture is still viewable but appears to be a bit skewed. Everything else works fine. This is a 2003 unit that states HD 1080 Goldstar on the front. It has been a great tv. I would like to know how to fix the problem if possible.
