SOURCE: 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.

Optoma gt700 is all green after replacing color wheel


we mainly retail or distribute color wheel, light tunnel ect sparet parts for projector or TV, so we have experience on that problem you faced.

perhaps you ordered a compatible color wheel,but it is not big trouble. compared with your old wheel, you will find a black tape, just make it as the same position as your old wheel, it will be ok.

My Optoma HD 200x projector has developed constant evenly-spaced white vertical lines on the image at all times...if it is the motherboard, where can I get a replacement from?


I has his problem with hd200x. Out of warranty so i opened it up, pressed down on the metal plate above the motherboard (left hand side with lens facing away form you) and hey presto, problem solved. been running for hours since with no problems. Might be a loose connection from hanging from a ceiling mount im not sure but its fixed!

Colors flickering


Easiest and cheapest to just fix it yourself! The problem is with dust/debris accumulation on the color wheel. Very simple to fix. Remove the lamp and you can see the color wheel. You may be able to clean it from that hole using compressed air. If not, you will have to take the outer casing off. A film will build up on the color wheel in certain environments, smoking, dusty areas, placement next to ceiling fans. To remove the film build up, use a q-tip with denatured alcohol. start from the inner part of the color wheel and work the q-tip upward towards the outer part of the wheel. you may have to remove the cover plate to the color wheel to clean the other side( side facing the lens). Not a big deal and will bring your projector back to its original vivid colors. As for LCD projectors, they are only good for one lamp. You will never get the full use out of a second lamp as the lcd panels degrade fairly quickly. Usually the blue lcd panel is the first to go. A DLP projector can last you for years and many replacement bulbs. Replacing a color wheel is fairly easy. Replacing lcd panels, not going to happen as they have to be calibrated and are very expensive. P.S. If you are a smoker and you do it in the same area as your projector, you will get a tar build-up inside the projector. The tar will accumulate on EVERYTHING and eventually lead to overheating as well as color wheel issues. The reason I mention this is I just repaired a Optoma EP721 (very similar to the HD65) that had this issue.

My Optoma 739's color wheel broke. Ordered new one, just want to know: Is there any instructions on how to take out old and once new one is in, how to calibrate new color wheel. thanks for help, Aurelio


you don't need to calibrate it. unscrew the bottom and rear screws, remove the top case, remove the boards (be sure to remember where the wires go that you remove), locate the colorwheel (between the lamp and the lens), unplug the colorwheel wire, remove the mounting screws, replace with new one, reverse the instructions, plug it in, turn it on, enjoy!

Optoma DV10 color wheel


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
