I have a 73 inch Mitsubishi DLP TV which I purchased new in 2007 from UE. Last year, the bulb failed, and I replaced it, and it looked awesome... like new. The picture has started to degrade over the past couple of months. Initially, there were just kind of "shadows", or during bright scenes, you could see blobs or bubbles of things that weren't normal. Now it has started to "flicker", and the color is not right.... sometimes everything is too "pink" or too "yellow". I have an extra new bulb, but this doesn't really seem to be a bulb issue. Could it be a mirror issue? Any ideas?
More info is required. What are your source devices? How is everything connected? Pics help as well.
