Just replaced burnt out bulb in Infocus 4805 projector. Great picture with new bulb but only black and white. Is this a bulb issue or something else in the projector?

This is most likely the color wheel. When the bulb blows, it can damage the color wheel. The color wheel is a wheel composed of thin layers of colored glass that spins in front of the projected image. It is possible to repair it with super glue, but the best way is to try to find a new one to buy.

My projector is making loud buzzing noises that arent normal.. I just ceiling mounted my projector its an InFocus ScreenPlay 4805 and the bulb has 1500 hours on it. The buzz started after it was on for 30...

If this sound you are describing is NOT constant and is intermittent in nature it is certainly not a color wheel problem. This sound is usually caused by failure of the Lamp cooling fan (the large one)'s Mos-Fet driver chip. Located on the bottom of the main board. These surface mount "chips" do fail and it's a fairly common problem however this is usually (but not always) accompanied by the projector shutting itself down after a few minuets or so as the high temp switch trips off. A color wheel common failure presents in two ways, either all the glass color filters fly off (there are six) and the image is monochrome (black and white) or just one or more of the segments has come off and the result is an imbalance of the color wheel which spins VERY fast resulting in a vibration
that is constant and can easily be felt by placing your hand on the projector. And all of these problems are very easy to repair.

Good Luck!

Color wheel failed. Can I fix it myself??

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.

Bought 3 MP3300 projectors for presentation projects

OK first thing if you have broken the disk on a DLP projector, you can not repair with out specialist equipment to set it up, as for your other ones it sounds like your lamps are faulty, you must not use lamps over the rated hrs or you will damage the projector, if you want more help just ask me but unfortunatly in am in the UK so cant vist.

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

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.
