I bought a used Clearco HD projector today. But when I got home and powered it on there was a brownish mark on the display (when it projects on the screen). Its not so bad when there are darker images but on light images (e.g. white) its quite visible.
Does anyone know what this is? I am hoping its just a bulb and not something more terminal.
Obviously I've been ripped off cos it was supposed to be sold as working. However there's not much I can do now about getting a refund (hard to explain) so please don't give me any advice on returning it.
I am just wondering if anyone can diagnose the problem (and provide a solution).
