I have just turned on our 18mth old projector run with sky tv after 6mths with no use. There is no colour, Before I think about changing the bulb (its only had max 200 hrs use over 18mths) is there anything else I can do.

    My projector is 24 months old, and about a week ago began projecting in a mostly blue color, the reds aren't showing up. Can't adjust on the menu on the projector or through the system preferences on the computer. Already tried connecting with different computers and using different cable connections the result is the same, a blue tinted image with no color.

Check poewer connection
Check if fan filder is dirty ( if it is just hoover it out)
If "lamp" light on top of the projector blinks or stays lit - lamp probably faulty
How old is the Projector/lamp (average lamp life is around 2000-3000 hours)

HD70 DLP Projector: The projector is used and about a year old. It cur...


Did this start occurring after you replaced the lamp?

The reason I ask is I had the same issue after changing the lamp and it was caused because when I took out the old lamp I noticed dust in the lamp housing which I attempted to blow away.

This caused the problem because some dust got further into the projector, specifically around the color wheel. I sorted it out by taking the projector apart following the instructions here:

http://tantht.blogspot.com/2009/02/how-to-remove-dust-blobs-from-optoma.html

(note my HD70 was out of warranty, if yours is not, I would recommend contacting Optoma to get it fixed).

Follow the above instructions to step 14 and then locate the color wheel which is at the front of the projector behind a dark gray, plastic type square shaped cover.

You have to be very careful here, but remove the color wheel (there is one screw holding it in place) - note it

The optics are dusty in an Optoma HD32 projector, I require a service manual which would indicated the correct method to remove, clean and reinstall the optics.


go to http://www.tantht.blogspot.com/ . He has excellent instructions for dismantling an optoma projector. However I took it one step further. I still had a problem with overheating due to dust after I followed his steps twice. Then I also removed the back of the projector which gave me much better access to an internal fan. I could see a substancial amount of dust coming out when I blew compressed air through it this third time around. It has been working fine for 6 months since.

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.

http://www.geekfest.info/DV10/dv10.html

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
