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.
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.
power supply needs to be replaced. you can get the part from an infocus service center, or send it to the to repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com
when you power it on, do you hear a high-pitched whir? if not, you need to replace the colorwheel. it's also the colorwheel if you hear a buzzing instead. if the colorwheel does not spin, the lamp won't come on. if the colorwheel is ok, check the lamp. is the screen on the side of the lamp clogged with dust? is the inside of the lamp bulging, spotted, or foggy? if so, replace the lamp and clean out your projector with canned air. dust blocks air flow and keeps in the heat. this shortens the life of your lamp and projector. if you do need the colorwheel replaced, you could get the part from an infocus service center and do it yourself, or send it in for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com
If you have any video at all and it's only Black and white there is a 99.99% chance that your Color Wheel has lost all of it's glass color filters. You can confirm this by removing the lamp. then look straight into the projector where the lamp was and you should see the color wheel of colored glass segments (Red, Green and blue) I believe you won't see them because they came off of the wheel. Also if you lift up the projector and turn it around in various angles and you will hear the small pieces of broken glass from the color wheel. Unfortunately you will need to take it to an authorized service center for repair. Be prepared to spend upwards of $300 for the repair.
if mains is ok and fan running ok, could be a bulb service issue, all lcd projectors have an internal lamp life counter which counts down and once the lamp has reached the end of its life it will not fire up and a new bulb will be required.
