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.

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 disc is broken and not repairable, problem is unless you know someone that can get the part you have to take your projector to an authorised service centre.
