Power up with top case removed to check fans and voltages
You can check the three fans and the lamp blower by removing only the top case and front bezel/bezel
vent. Once these parts are removed, you can power up the projector and verify whether each fan/blower
operates.
While the top case is removed, you can also check voltages on the fans and on the power
supply/controller connector.
1
Remove the following parts:
Top case (see page 19)
Front bezel and Front Bezel Vent (see page 10)
NOTE
The lamp and the lamp door must be in place to start the projector with the top case
removed.
2
Use a compatible remote control to power up the projector. To do this, point the remote at the
rear of the projector and press Power.
If you do not have a remote, go to page 110 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.

Do one or all of the following:
Check controller ECA voltages (see page 101).
Check the thermal switch (see page 105).
Follow the directions below to check fan and blower operation.
