    I changed the bulb in my Optoma EP 739 and now there is no power to the projector. Have checked lead and lead fuse, changed back to old bulb and still nothing. Is there an internal fuse in the projector?

    I have exactly the same problem as safety395. I've checked the plug fuse and the lead, changed back to the old bulb, re-tightened the bulb setting screws and the door screws but still no power to the projector. Is there an internal fuse or some switch that needs re-setting?

The lamp exploted in less than 30 hours of use, replaced an exploted in 4 hours, replaced and exploted in 5 minutes what can I do?


Is it the correct bulb? Or recommended bulb? Try a higher wattage or lumens. I'm not sure what the lamps in the projectors are called, but check on the wattage and lumens.

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...

Power will not come on.tried many power chords none work light will not come on


are there any leds on? if not, replace the power supply. if there are, such as one blinking red, could be the colorwheel, ballast, or the lamp has expired.

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


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.

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!!!!

We have an optoma ep739. when you turn the lamp on, a message 'fan failure' comes on. the fan is running at what appears to be a slow speed. the red temp light goes on and then the lamp turn off.


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.
