Have to program my bedroom direct tv HD with my shows to keep up while dropping from 102" down to 52" sony Bravia while Optoma is out of commision.
I'm experiencing the same problem. It has progressively gotten worse as time has gone by. Now the machine is telling me that I need to replace the bulb at only 1500 hours. I feel as if the auto shutdown problem is somewhat responsible for this early bulb replacement. How has Optoma handled warranty issues related to this autoshutdown issue? It seems I've read a number of owners with similar problems so hopefully their techs understand the problem right away.
I'm also curious if there is a difference that can be seen from 1080p/24 vs 1080p/60. I've been switching between the two and can't seem to tell a difference like I can on other LCD tv's.
one other thing worth mentioning about the projector shutting down early, switching to High Altitude mode with the increased fan speed helped the unit have less issues, but still in time it did get worse.
