You can try giving a good slap 3 inches behind the lens for an unlikely long term fix or you can take the projector apart and reseat the main board to the light engine. However most likely the dmd on the light engine is bad.

We have an Infocus Screenplay 4805 projector. Our colour wheel has broken and we don't seem to able to purchase a replacement part from anywhere. Any help much appreciated!


Same problem... The manufacturer actually does not sell this part. You must simply purchase one off of craigslist or a broken projector and fix it with the parts. Here is a website that shows you how. http://home.comcast.net/~jexkids/Ebay/colorwheel/How_to_replace_Color_Wheel.htm

The picture suffers from colour fringing


either the color wheel has lost a segment or the colorwheel index needs to be adjusted in the hidden menu using the color ramps test screen.

7 wide black vertical interference bars on all screens. Equally spaced with normal looking segments. Like the stripes on a flag. On both maintenance screens and program screens, too. The bars are "fizzzy"...


if these lines are pulsating, it sounds like the connection at back of the engine where it connects to the main board. you can try to reseat it and see if that fixes it. otherwise it could be one or the other. really hard to tell without a test fixture. if the bars are fuzzy like they look like they may be underwater then that would be a bad light tunnel.

Picture colour is wrong. Too much green and pink.


first reset the settings to factory default. then swap out the cable. if you still have trouble, replace the colorwheel.

Blurry screen


Sounds like focus is out. These projectors are like cameras; they have an optic with a focus ring. Try rotating the focus. Some have electronic focus as well. If the manual focus does solve the problem, look through the menu for a focus setting adjustment.
