I've had my LCD projector now for a few weeks, and though I love it, I do have a small problem. There is a small green spot near the top middle of the screen. Actually if you look at it closely enough, it is one dot directly overtop another, so two green dots. During widescreen viewing the dot is about vertically and horizontally centered in the black bar. Very noticable overtop the black bar. During 4:3 or fullscreen viewing the dot is really not that noticable, unless the screen is dark. Since I first noticed it I suspected it was a stuck pixel, and was not sure if this kind of thing is covered under warranty? I have read that an hour or so of displaying a static screen might help, so I will try it but I have my doubts. What can I do about this?
