Question about Sanyo PDGDSU21E DLP Projector
This may be dust on the inside of the lens. If you recently changed the lamp, you may have disturbed some dust inside the projector. Try focusing the projector so the white spots come into focus. You might be able to see that it is dirt, hair or a dust ball.

Unplug you projector and allow the bulb to cool. Open the area where the projector bulb is located. Check the projector lens for any damage and clean it from dirt's and dust. Same as with the bulb.
