Check the Color Wheel and Reseat the Cable

If the color wheel cable is not properly seated in its ZIF connector, the color wheel will not start when the

Power button is pressed. When the color wheel does not spin, there is no lamp enable signal, and the

lamp will not strike.

Normally, you hear the brief high-pitched sound when the color wheel spins up to speed. If you don't hear

the sound, or if you are not sure, you can do a visual check to confirm the color wheel operation.

If the color wheel is not spinning, the first item to check is the color wheel cable connection and reseat it if

necessary.

To check color wheel operation and reseat the cable, do the following:

Power up the projector with the top off (page 64).

NOTE

The lamp and the lamp door must be in place to start the projector with the top case

removed.

Examine the color wheel to see if it is spinning. The color wheel is inside the circular shroud on

the optical engine.
