either the lamp hours are close to or exceeding 1400 hrs and the lamp needs replacing, or the ballast is starting to fail. with the projector on, check the lamphours in the menu. after you replace the lamp (if it needs it), reset the lamp timer by holding down the down arrow, right arrow, and enter buttons, then press power.

SOURCE: projector lamp shows blue on white screen

the red is cutting out. white=blue+green+red. without red, you get blu+green, or cyan. if this was an lcd projector, i'd say it's a burnt light filter, the red lcd, or the lcd has come unplugged. but since this is a dlp projector, you have either a dmd board issue or a main board issue. either way, it'll be pricey.

SOURCE: The projector does not show

It could be 3 things--
1. You need a new cable
2. This is unlikely, but the red segment could be off the colorwheel, but if this was the case the wheel would be way out of balance and the projector would be vibrating like crazy.
3. The "color ramps" or colorwheel index in the hidden factory menu may need to be adjusted.

My projector won't project anything. the computer recognizes the projector, but the projector does not recognize the computer. also when i turn on the projector the benq logo doesn't show.


Disconnect all inputs to the BENQ and power on. Do the lights come on as per normal operation. Does the lamp come on when the power button is pressed. Does anything show when the menu is selected.

My InFocus 4805 SP projector is showing just black and white


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
