I removed the front cover and top panel, Using the Radio Shack dust removing spray, removed all dust from interior including circuit boards, color wheel ect, now it,s operating like a new projector.
I'm not the original poster, but I ran into the same problem with my Optoma GT700. I tried megadeth's tip and it worked perfectly!
