Question about Optoma EP738 Multimedia Projector
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?
A 6ya expert can help you resolve that issue over the phone in a minute or two.

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.
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.

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!!!!

take the lamp out, there is a fan directly looking to the lamp... clean it with a compressor. and after that at the menu of projector there is a place called 'High Altitude'. turn it on. And it'll be fine...
