Check The Color Wheel And Reseat The Cable - InFocus X1 Service Manual

Check the Color Wheel and Reseat the Cable

If the color wheel cable is not properly seated in its connector, the color wheel will not start when the
projector powers up. 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 does not spin, the first item to check is the color wheel ribbon cable connection and
reseat it if necessary. The cable seats at connectors on the color wheel and the controller ECA.
To check color wheel operation and reseat the cable, do the following:
1. Power up the projector with the top off. (page 80)
NOTE The lamp must be in place and you must close the safety switch to start the projector with
the top case removed.
2. Examine the color wheel to see if it is spinning. The color wheel is located between the
lamphouse and the optical engine.
3. If the color wheel is not spinning, check the ribbon cable connection. The ribbon cable inserts into
a connector at the color wheel motor.
