I repair electronics professionally. I have repaired dozens of PRM-25 projectors that give a color wheel error. The problem is usually not that the color wheel is broken, but that the color wheel cannot spin, because so much dust has collected inside the projector.

What I do is open the case, and carefully blow out all of the dust with an electric duster. While I have the projector open, I also take out the two fans that come out easily (one is on the side, near the lens. The other is next to another fan, but it's the one towards the back of the projector). I clean those separately, and I even use a detail brush to get into each fan blade. I also put the duster nozzle into the blower vent and blow it out.

TIP: Be careful! the color wheel is made of very delicate glass.

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.
