Reviving an old thread. I started getting the dreaded white spots on the screen, thanks to a faulty DMD chip. I called Optoma asking about this, and to my surprise, even though the projector itself only has a 1 year warranty, the DMD chip has a 3 year warranty. Fortunately I'm under the 3 year threshold, so I was approved for an in-warranty repair. I don't think I saw this info on this forum, so I wanted to pass it along.
