Projector picture has a darkened quarter screen on a angle


Ok I guess you have an optical mirror chamber error sounds good doesnt it but can happen if projector has been knocked or dropped in the optical engine there is a chamber connected in between the main lamp and internal glass lens you may see it if you look inside the lamp assembly this very small chamber has four very small mirrors in it and is held in place usually by a metal plate bracket you may find one of the mirrors has moved or dropped this makes the refraction of light incorrect which will cause your dark shadow on your image screen

The other possible cause in a Optical light engine which might be very expensive to replace in this brand.
