Optoma EP739 overheats and powers down after 30min use

My EP739 shuts down after 30min of use in normal room temp. This started after one nights use in a night club that was filled with smoke from a smoke machine. my thought was that the fan is running slower due to sticky residue? i could do with some advice on this perhaps where to buy and how to replace fan? is there more than 1 fan? any thing else it might be?
thanks

Hi,

One good thing is that you are running XP. Will work on the premise (that you have posted) worked before and the driver (ForceWare91.31) was the only thing changed.

Let's try the easy ones first. Activate twin/dual view in your Display Properties. Right click on any clear area of your desktop, click on Properties, click on Settings tab, select monitor 1 or 2 depending which is your primary and which is your projector. Check (or uncheck-whichever works) on box "Extend....". Apply, OK.

or

do the same with nView Properties.

The hard ones are registry and/or inf editing, though I am reluctant to even suggest.

Incidentally, there is an application that is supposed to facilitate twin or dual view configuration, UltraMon. This may be better/safer way to address your concern.

If all else fails, you may have to rollback/downgrade your driver.

Cheers.

SOURCE: optoma ep739 won't power up

The lamp cover has a disconnect that won't allow power while the cover is off. Sometimes the piece of metal gets bent out of place.
Try removing the cover for the lamp, and bending the little piece of metal forward.

It worked for me!!!!

On my optoma H77 I am replacing a burnt out bulb with a New one. The ''TEMP'' light blinks immediatly without the projector getting up to normal opporating temp. Is there a ''Reset'' button ?


clean out the projector with canned air to get rid of the dust that could be causing it to overheat. also make sure the fans are spinning. if it still blinks, replace the temp sensor. if it overheats alot, the sensor will wear out from excessive heat.

Optoma ep739 color was going greenish so i replced the bulb and now it seems to be getting no power at all? i tried several outlets and still no power, no flashing light, no led, nothing. Any suggestions?


These units have many safety interlocks. First make sure that all of the doors that you opened are replaced correctly. If not, the interlocks will prevent any power from getting to the unit. Update this with what you find.

Optoma EP739 Projector Overheating


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.
