I've had my projector for around a month or so and am starting to notice more and more what I presume to be dust blobs appearing on my screen. At first this didn't bother me too much, but I've just finished watching Pride and Glory and have noticed a rather large red blob being projected on dark scenes. To be honest, I cant even tell you what the film was like as I spent the whole 2 hours watching this blo%^y red patch keep appearing. On inspecting my lens (after it was switched off), you can see what looks to be a red mark on the inside of the lens. It looks as though the heat of the bulb may have caused it. Does anyone have any suggestions on how I can get rid of it, or do I just call the place I got it from and tell them that I'm not happy? Any advice will be welcome.
