HELP please!

I have a Sanyo projector. Looks like dust on the image in some places - splotchy patches (not uniform), noticable in lighter scenes, not really in dark scenes. I used compressed air to blow off the LCD panels - no luck. Took it to a 'repair' guy - he charged me $100 to clean it - looks the same to me. If you click on the photo to enlarge it you will see what I mean - especially near the top of the screen. I THINK it's dust but would like some feedback before I take it back to him. I am not an expert.

Hard to tell from that photo. Maybe a constant gray frame would show it better. If you have a computer connected you should be able to try different solid pastel colors. That would eliminate source being the issue.

Thanks for taking the time to reply. I ddi try a different DVD player but had the same result. The photo distorts the colors - the background is white, not blue and the splotches are tinted reddish. could it be anything other than dust?

Thx

Assuming you've cleaned the screen you're projecting onto and there are no problems with it?
