Colorwheel may be bad or the power supply is.

first check to see if it's overheating. there is a thermal shut off if the projector gets too hot. blow out any dust with canned air. if that is ok, it would most likely be the power supply. if the projector gets too warm (or just from excessive use), the capacitors on the power supply (and/or the lamp ballast) will dry out and no longer hold the proper charge. if the caps are puffy, you can replace them. if they are not puffy, it's hard to determine which one is bad. best to replace the board.
