Optoma EP739 Projector Overheating




By rlwills on Mar 09, 2008

" "
We have an Optoma EP739. It started shutting off with the message "Projector Overheated" on the screen. I cleaned all the vents and the fan but it still does it. It is three years old and only used on Sundays. It just started this about 2 months ago

Same Problem

-   Seems this is a common problem.  I have the same issue.  I have put a small fan to blow away all the hot air.  THis helps, but its not a solution -   Guest

-   We have 2x EP739 projectors at our church and are both about 3-4 years old. Both over the last 6 months have had the 'overheating' fault and will only last a max of 45 mins before they shut down!

-   Same symptoms. My projector is about 4 years old. Used to work fine but now will only run about 45 minutes if cold. If already warmed up it will only run about 15-20 minutes before shutting down.

Verified fan is running all the time. I even put a home cooling fan near the unit and it still overheats but not as fast.-   john_schiman

Set the projector to "high altitude mode." It will be noisier, but won't overheat. I wonder whether using one of those $10-$20 laptop coolers underneath it might be a quieter solution.
