viscera

I have a philips ProScreen 4600 projector. It can be used for computer display or any kind of video display. I am using it for DVD. When I am watching a DVD the people or the objects have a red silouette on the left side and a green silouette on the right side. The silouettes are in the form of horozontal lines, and they will disappear after a while but eventually return. Basically my picture isn't coming in totaly clear. Anyone have a clue as to what I need to adjust on it or replace? Also sometimes it is really bad with the red and green when you turn it on, and it won't disappear.

thanks
