Projector My Optoma TX1080 projector needed a new color wheel. I opened it up and swapped out a new one and now once I've put the projector back together, all of the power lights light up properly and it powers on. The fan spins and I hear the color wheel spooling up as well. The lamp never fires and as I let it sit, eventually the fans get louder adn the blue power lights switch off and the red lamp switches on. I have a brand new lamp and the old lamp (white was working fine before the color wheel swap). The projector then after a while repeats this process of turning on and then off with lamp light. Ideas anyone?

Usually, that means that there is an issue with the cable connecting the computer to the projector. Check to make sure none of the pins are bent or broken. Aslo see if a differnt cable works correctly.

Take the lamp out and look for signs of darkness on it or possible bulging. Sounds like the bulb is going bad.

Hi!
Is the projector placed in a box or an area where it could generate overheating? Is this projector still within warranty?
Please feel free to update me. Cheers!

The piece that's cracked is called a color wheel. I spoke with the parts department at optoma and they want $300 for a new color wheel for my ep 732h projector. I'm not sure if it's the same part but you can contact optoma on their website and they'll get back to you with a price quote for that part.

If you contact Optoma and they have the part available then, yes you can fix it yourself. You have to be good at taking things apart and remembering how they go back together. Changing the color wheel assembly is not that hard.

where i got Optoma HD70 DLP Projector spears

The color wheels for these projectors can run anywhere from $50-$150 plus installation. With projectors now in the 3-400 range it may actually cost less to replace instead of repair.

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

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.
