Optoma h31 color wheel - Optoma H31 Multimedia Projector

SOURCE: I have the optoma h31

I had a similar issue with my EP739, the problem would start after about 3 or 4 minutes and then get gradually worse and worse..
The most strange thing I noticed was that white looked fine. And if you opened the configuration menu in the projector it appeared that blue was labeled green and green blue..
Some sites suggested cleaning the machine of dust, which I tried using a can of compressed air... This did not fix the problem at first.. but when I had it apart I studied the colour wheel for a little while and wondered if some how the machine was synching to it incorrectly somehow.. So I blew out the colour wheel location sensor (It's kind of obvious being the only component mechanically connected to the color wheel. Much to my delight, this fixed the problem...

So my solution to the flickering / colour fading / colour swapping issue with DLP projectors was to clean out the dust from the colour wheel location sensor..

In fact, if I did it again, I would ONLY clean the sensor, and leave the rest of the dust alone. Blowing dust around has the potential to cause other issues, especially if it winds up inside the optics system.

Theres a guide on this on one of the home movie theatre forums and also some colorwheel guide on brit ebay but no color wheel supply that i know of.

SOURCE: Optoma h31 was unable to power up

It can have two problems. One is that the lamp has gone out and needs replaced. Refer to your troubleshooting section in your manual. Also can be bad capacitors in the power supply circuitry or Voltage Reg. IC. Either should be left to competent repair individual.

Okay, I recently had a loud noise coming from my projector and found online meterial stating that the colour wheel had been damaged. So with a bit of guts I managed to open the projector and found the colour wheel missing a segment.

I removed the colour wheel and the broken piece of the segement and tried to contact Optoma. Optoma turned round and said they cannot sell me the the colour wheel, which got me very upset. Some people claim online that Optoma will sell you the part on a back order at £50. (if you can be a little specific on how you managed to convince them to sell you the part, would be great).

The only option I had available was to send my project to them and they would repair for an estimated cost of £125+VAT. Guess what, you can buy the entire projector off ebay for 150quid!!!

Anyways after fiddling around quite a big online I got fedup and decided to glue the broken segment together and it SOLVED the loud vibration problem. I have colour and picture.

Becareful not to tighten the colour wheel screw too tight orelse it will break another piece of segement (Like I did).

Here are instructions on how to open up the projector.

I cannot guarantee this will work for you as it depends on how badly you have shattered the colour wheel segment, so do at your own risk. I had two piece of the segment broken and a third by tightening the colour wheel screw too tight.

This will work for awhile but the colour wheel does need replaceing one day. If anyone can tell me how you can get Optoma to sell you the colour wheel would be great.

Best of Luck
