Check The Color Wheel And Reseat The Cable - Toshiba TDP-S3 Service Manual

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. Reseat it if
necessary.
To check color wheel operation and reseat the cable, do the following:
1 Remove the following parts:
Top case (see page 20)
Front bezel and Front Bezel Vent (see page 13)
NOTE The lamp and the lamp door must be in place to start the projector with the top case
removed.
2 To power up the projector, point a compatible remote at the rear of the projector, and press the
Power button on the remote.
If you do not have a remote, go to page 98 to see how to power up the projector with the keypad.
CAUTION When you power the projector up, there is voltage present on the controller ECA and power
supply. Be very careful where you probe and where you touch.
