Re: Color wheel for a 4805

You are describing two separate problems. The line (or shadowing) on one side is a light tunnel failure. The whining noise is a color wheel problem. It wil either freeze up eventually and the projector will shut down or the glass will shatter and you have a black & white image.

Re: 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..

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

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.

    Glass prism


    Thanks for contacting us regarding your product questions or concerns. It appears you are wanting to know how to reach the glass prism from your 4805?

    My initial question would be, why are you looking to access the glass prism in your 4805? This is a very dilicate process internally of your projector which helps it opperate. Are you trying to self-repair your projector?

    Let me know. I'll be waiting for your reply.
