When I hooked up my Infocus projector to my desktop, the display had a red tint. It is not the bulb; I hooked it up to my DVD player and it was fine.

Usually this is a hardware acceleration setting problem on the 'advanced' properties setting in your 'screen resolution' properties on your computer. Re-set the hardware acceleration to the 2nd setting and this should fix your issue. We have this regularly when we project on a double projector system and the one projector keeps shifting everything left until we adjust the hardware acceleration settings on the computer. No more issue.

You have to go into projectors' menu and tell it what the input is. Scroll thru menu and you'll see a handful of options for input.

replace all cables with NEW ones.

make sure you have the correct input selected. if you're using a computer, make sure it's on computer and not component.

first swap out the source cable. if the problem persists, reset the settings to factory default. if the problem still persists, your colorwheel may be bad.

if it only has a blue tint when the computer or video is hooked up, reset the settings to factory default and replace the cables. if the splash screen (when it says "infocus") has the blue tint, one of the light filters are fried due to excessive heat and dust. unfortunately, you'll have to replace the entire optical engine.

make sure you're on vga and not component input. it's a dlp (there is a colorwheel), so no bad lcds.

it there is no high-pitched squeal when it starts up, the colorwheel needs replacing. the lamp won't light without it. the part is under $50, but installation is quite involved.

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!

The bulb won't do that. What you're describing sounds like a light tunnel failure.
