Question about BenQ PB7220 XGA DLP Projector Multimedia Projector
Hi ; My DLP projector is throwing the light unevenly on the screen...if I shake the projector the uneven pattern changes form, usually is a rainbowish line that cuts the corner of the screen.... ....the lamp has only 700 hours and is still bright....any sugestions would be great...I'm going to try and open it and air blow the dust out...that seems to fix most peoples issues....not to mention my last place was rather dusty..
This is true, Projector prices have come down lately. LCD might not be a bad way to go. They have made remarkable improvements in respect to the blacks. And compared to DLPS they have one less moving part. Also some places are offering an extended warranty including 1 lamp replacement, So, check around and see what you can find. Good luck on shopping. Have a great day. Talk to you later.

Actually you can turn the projector on and then tilt it in all directions and see if picture shadowing changes. I have experience with this issue on DLP TV'S. IT sounds like a light tunnel problem if you can see partial picture behind shadow. It is fixable but very tedious. But can be done. Do you have a picture of the problem that you could send over? Thanks Jay
