Check to be sure that the projector is in the correct mode. If it is expecting an RGB signal and you send it (Y,Pr,Pb), you will see the picture as you describe. The same works for the above reversed. In all likelyhood, you are sending RGB and the projector is expecting the other.

After 10 minutes the colour wheel get out of synch and then a few minutes after that there is a crazy squeek and the lamp red indicator turns red light and the unit shuts off. I have opened up the unit...


Hi
Clean the Color wheel sensor thoroughly. a lens cleaning solution might help. be careful.
If problem persists.
Intall a 1" fan throwing air into the vent near height riser stud. into the color wheel chamber. this works.

Colour is very lacking in contrast


This could possibly be the colour wheel or the texas instruments dlp chip.

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.

Optima D10


Well, in the USA I understand it's
Part no: 70.18r26g01
Cost: 129.00+shipping BUT CHECK THE PART NUMBER IS CORRECT
Model :Optoma DV-10
Contact no: (408) 383-3710 or 888.942.2929.

In the UK I don't know of a colour wheel supplier although I suspect 7-segment colour wheels from other manufacturers MIGHT fit, but it's a gamble and you'd need to check with them before spending any money in case it doesn't fit.

One company that has spares for Optoma is BlueGoose Systems but they don't have the colour wheel. Well worth speaking to them for other parts, 01624 671719 www.bluegoosesystems.co.uk for an online 'gander' at what they have in parts.

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

Color problem


Hi christisfree

Try using a different cable that you connect from your source to the Projector.

A colour change is normally a faulty cable , but if the problem persists after changing the cable , then you might be in for a new Mainboard.

Try the cable and get back to me on this one.

I have the optoma h31 projector and the color turned purple. We assumed it was the bulb and put a new one in. The color is now still not right and the picture sorta bounces


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.
