SOURCE: Color wheel for a 4805

I've encountered this same issue. I had a large Yellow Line down the left side of the screen for a few months. It got bigger and bigger, then one day I was using it and Bam! What sounded like a fire cracker was my color wheel exploding. I also had the rubbing sound, or at least something similar to that sound prior to the explosion. InFocus quoted me about $300 to fix..

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.

as for a replacement colorwheel, try http://online.projectordoctor.com/. as for putting it back together, just reverse the order of the dismantle. general rule of thumb: larger thread screws go into plastic, smaller thread screws go into metal.

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 Infocus 4805 is just showing the INFOCUS logo and not showing the picture from the TV. all connections are correct but no signal....help


Powering On
  • If your InFocus 4805 projector is having a hard time powering on or doesn't power on at all, it could be one of two things. Due to the extreme temperature of the lamp that causes the temperature of the projector to rise, every InFocus 4805 projector has a cooling system. Check your projector's cooling solution, as it may need to be replaced. Also check the projector's fan---if the fan doesn't spin, the unit will not turn on. If the problem is the fan, you'll have to get it replaced. You can do this at the same place you bought your projector.
  • The Lamp
  • If your InFocus 4805 Projector powers on but does not project any light, the lamp will need to be replaced. All projector lamps must be replaced at some point---how often usually depends on how much use the device gets. Simply order a replacement lamp, unscrew the old one and screw the new one in. The projector will then work like new.
  • Color Wheel
  • If your InFocus 4805 projector powers on and is displaying images but the colors on the images appear warped or are not in the proper places, your "color wheel" will need to be replaced. The color wheel is a small device that essentially acts like a prism. Light is projected through it and it displays the appropriate colors on screen the way they appear in the original video source. Order a replacement color wheel that fits your model and use your instruction manual as a guide as you swap the old one out and put the new one in.

    Color wheel sounds like a buzz saw. Fan is quiet because there is no noise in the cool-down mode. Can this be replaced by user?


    Baily, I have had my HC1500U color wheel replaced two times due to the color wheel's unpleasant "buzz saw" effect showing up every few thousand hours of usage. It is happening again for the third time and I am still within Coscto's warranty so I am going to have it replaced again...will never buy a DLP projector again...too many moving parts that can break!

    Would love to be able to replace it myself if you ever find a place that sells the color wheel.

    Shattered color wheel


    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.

    I heard a pop and now the projector only shows black and white.


    The color wheel has failed in youtr projector. There are 4 pieces of glass in the color wheel which fit togeter in a "pie" formation and they are red, blue, yellow & clear. This wheel is spun by a motor. The glass is glued to the motor's hub, and, when it fails the glass segments are thown off the hub. This gives you a B&W picture because all of the light is allowed to shine through the optics all of the time. Replace the color wheel with Toshiba part no: 23125963. It will be about $65. No soldering is involved, just use care with the ribbon cable to the motor. You will need a no. 2 phillips screwdriver and a set of jeweles screwdrivers to do this.
