My Ae100 has developed colour staining down the sides. It used to have a geenish patch in the top left corner and a purplish patch in the bottom left. These seem to have disappeared but now there is staining about 6 inches wide down both sides of the screen from top to bottom. If I'm honest I would say that most of the time I don't really notice it. Its only on certain scenes or black & white images that its really noticeable. The thing is, I think I remember some people saying they sent their PJ's back for this problem. What happened? Did Panasonic repair them or replace them? If they repair them then I don't think I would bother as the staining doesn't bother me that much and I couldn't be without my projector for an extended period However! If they replace them and seeing as the AE100 has been superceded by the AE200-300, then I could be persuaded to 'complain' and demand a replacement. What do you lot think?
