Can the Optoma EP739 be ceiling mounted and projected upside down? what are the steps to do so? also, what would be the best mount for said projector?


Mine has been in place for about three years. Because the ceiling was open I was able to create a connection for a tripod head on the ceiling and then using a STRONG tripod head and some small bolts (longer than the originals) I mounted an external base and with the tripod head fitting dttached to the projector it just became a matter of running the various connector cables from the sources I use that require projection to my wall.

EP739 projector has been overheating the last 6 months.


Its getting old...and generating more heat...
There are fans inside the projector that **** in ambient
air and blow it across the parts...A quick fix might be
to lower the room temperatrue a few degrees...or
you could get a small fan, place it along side the projector
and have it blow additional air into the projector...

The projector is running at borderline temperature...

Also, make sure it is on a flat hard surface...and not
resting on a cloth or towel or rug...there isn't much space
between the bottom of the projector...to **** air in...and it
needs all that space...

You may want to make sure the AC line voltage is 110 -120 VAC
even a slight drop in this voltage will cause the projector to run
less efficient which means running hotter...

We have a optoma ep739 used at our local football club;but whenit gets warm it cuts out until it cools down;isthere any filters that need cleaning


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...

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.

The lamp cover has a disconnect that wont allow the unit to power on while the cover is off.

Try taking the lamp cover off and bending the little piece of metal you find underneith.

It worked for me.

Color bleed and Fan


I had similar problems with my EP739 shutting down in the middle of a presentation. Optima told me to run the fan on the high altitude setting. But the real problem was I was setting the computer too close to the projector, and the hot air from the computer was being sucked into the projector. Once I learned to set the computer away from the vents on the projector, the problem went away.

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.
