Hey, anybody know how to diagnose this without replacing multiple parts? Testing the ballast? Testing the ballast supply board? I read in one thread there is a resistor that fails, which resistor - location? Billyray posted he had a manual - DLP training, Atlantis Chassis March 2004, anybody have that? Any help would be appreciated, I'm frustrated without a logical place to start. I turn on the tv and hear the fan, then the color wheel - sounds like a hard drive booting up, not loud or whining, though, shuts off, cycles 3 times, always the green light flashing. As soon as I power the tv up, the green light is already flashing even before the color wheel is spinning. Maybe someone fixed theirs' outside the bulb, ballast scenario.
