My infocus 4805 only projects in black & White. NO MORE COLOR. How can i fix this?

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.

Your projector is DLP technology. It employs a "color wheel" to provide colors other than blank/white. That "pop" you heard unfortunately may have been a malfunction of the color wheel mechanism, probably the motor. (It runs at very high RPM)

Sounds like you may have to find a shop to service your projector.

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.

if I had to guess, I'd say your colorwheel is caput. If you have color on other sources though, it is likely your cables.

the color wheel has fallen apart and must be replaced. try googling the manufacturer for service.

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.

Cheers

first reset to factory settings (menu, settings, factory reset). if problem persists, replace the colorwheel.

Either the color wheel has thrown off all 6 of it's colored glass filters (most likely) and needs to be replaced. Or in the picture menu someone had turned the color all the way down (Less likely).


Good Luck!

Hi Stella,
There is a button on the projector called "Auto Image"
Most people don't realize it's even there.
Press it while you are seeing this problem and most likely the projector will figure out the image issue and all will be well.
Note: this feature is nowhere in the menu(s)

Good Luck!

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.
