Toshiba MT200 screen 'circles'

[Phaedrus]

Hello all,
I seem to have these 5inch circles on my screen when displaying an all black screen. There are four in total although they are two groups of two circles that overlap each other. These circles are slightly lighter than the rest of the the black screen. Any ideas? Thanx!!

It's probably bits of dust inside the lens or somewhere in the optical path of the PJ. You can check for this by playing with the focus. If you can bring the blobs into focus (or closer to being in focus), then it's dust.

Thanx!! It was dust...or crud of some sort. I exchanged the projector for another.
