    I bet the fan is also causing my over heat condition.

I had this exact same problem. I have changed bulbs gotten 1000 or so hours from new bulb, changed the lamp driver and gotten about 600 more hours from new lamp driver. New lamp cost me $350, lamp driver cost me $120. Then I read on a page to try and flip it right side up, because I had it ceiling mounted upside down. I flipped it right side up and it works perfectly and has been working perfectly for 2 months now. I know it sounds stupid, but it actually worked for me, and it costs you nothing to try it. For some reason, gravity effects this unit. Good luck.

I had the same problem with very few hours on the lamp. Sent it back to the factory and they said the fan was overheating causing the bulb to shut down. They replaced the fan and the bulb for free under warranty. I noticed before I sent it the projector was putting out an incredible amount of heat. MUCH better after fan replacement.

Color wheel sounds like a buzz saw. Fan is quiet because there is no noise in the cool-down mode. Can this be replaced by user?


Baily, I have had my HC1500U color wheel replaced two times due to the color wheel's unpleasant "buzz saw" effect showing up every few thousand hours of usage. It is happening again for the third time and I am still within Coscto's warranty so I am going to have it replaced again...will never buy a DLP projector again...too many moving parts that can break!

Would love to be able to replace it myself if you ever find a place that sells the color wheel.

New Bulb (30 hrs). Screen flickers after 10 minutes, color changes with green tint, then bulb shuts off.


Hi, I had a similar problem - the screen flicked through blue, green and red sometimes with a slight ticking noise. The problem seems to be that the colour-wheel is getting stuck - the first time this happened I sent it back to optoma who gave it a clean - it has happened again since thouegh and I just took the case off (you'll be able to see the colour wheel under a black plastic flap - remove the flap) I then used a cotton bud (q-tip) and turned the colour wheel whilst lightly pressing the cotton bud against the wheel - I also gave everything a blast with a can of air. My HD72i is ceiling mounted - optoma suggested putting the hoover pipe across the vents every now and then to keep the dust down. Essentially it's dust that is stopping the movement of the colour wheel.

Hope this helps.

Can you tell me why the optoma HD72I lamp will turn off after just a few minutes of running, the lamp is still fine


I have the same problem. I got a new bulb and it worked for about 1000 hours, then the new bulb started having the same problem. So, I was about to buy another bulb, and I figured why not try the original bulb. IT WORKED! For a couple weeks... Then it started doing it again. Obviously there was nothing wrong with the original bulb, and there is nothing wrong with the new bulb, but I have 2 bulbs that do it now. So, is there any way to just tell the projector run the bulb till it actually dies and not turn it off because it thinks it is about to die.

Optoma DV10 MovieTime Color Wheel replacement


Hi guys

Your best bet on getting your hands on a Service Manual would be to contact Optoma themself.

As for changing the colour wheel , it is pretty straight forward if you were able to open up the unit and get to it.

The colourwheel is mounted with three tiny scrws to a bracket in which it sits. And the bracket in it's turn is fastenend to the body of the Projector with two tiny screws.

First unscrew the bracket from the casing of the Projector and then take off the three screws that holds the Colour wheel to the bracket. Replace and do the whole proses again - but obviously just the other way round.

This is really easy to do yourself.

Give me a shout if you need any further assistance.

Thanks for using Fixya and good luck.

Worked! The safety switch is kind of hidden and enabled usually when the cover is placed. Be careful though because it is metallic and conducts the electricity!
