Question about Optoma EP739 Multimedia Projector

Open Question

My Optoma EP739 is having a fan related problem. Seems as though when I turn it on the fan doesn't start and it also makes a very loud buzzing noise that is intermittent. I blow on the fan and then it might kick on, but even after it does, the lamp will kick on and then shut off after a second or so, it repeats this cycle over and over again. Was wondering how I can check to see if there is a short in the wiring or if its the unit thats faulty?

Hi there

Try cleaning out the fan by blowing it out with a compressor. Most of the time this is only caused by dust.

If the problem stil occurs , try spraying it on the inside with a lubricant.

If the problem stil occurs you will have to replace the faulty fan.

Very cheap to have replaced.

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!!!!

Optoma ep716 continuous loud vibration noise when turned on.


the fan motor could be failing. turn it on with the top off. if one of the fans is moving slower, that'd be the one. since this is a dlp projector, the colorwheel motor berings might be on their way out as well. both need replacement.

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.

Dvd10 optoma projector makes a loud noise


Hi, I'm not sure if it's the same problem I had..
I had it on picture mute, for maybe 15 mins, which may not have been a good idea. While it was muted, it made a sparking sound, and then a very loud grinding noise. When turned off, the lound noise stops, and the fan continues as usual for about a minute. As soon as it's turned back on, the grinding noise is back. But the logo seemed to display ok.

I took it in for repairs, and they said they needed to replace the color wheel to fix the problem.

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.
