| hitachi 1200 problem We have a Hitachi 1200 projector. It's run maybe 60 hrs. Was doing fine until a couple weeks back. We have the unit hanging from an overhead mount, in free space. All of a sudden, the temp control is shutting us down because of hot bulb. The bulb isn't really the problem. Do bulb indicators fail? My feeling is it's a bad indicator that thinks it's too hot. What should I check? | |||

| Re: hitachi 1200 problem If the fans are operating and the airflow is not restricted, you could have a bad thermal sensor. Very common failure point on projectors.
