• Check the filter element. Clean or replace it if necessary. For
more information, please refer to Chapter 4, Maintenance.
• Check the rear exhaust vent. If the projector has reached an
overtemperature condition and the fan is working, you
should feel a strong rush of hot air from the vent. If the fan
is not working, the projector needs service.
After the projector returns to its normal operating temperature,
the TEMP indicator will go out. To turn the lamp back on, first
turn the power switch off and on again, then press the
STANDBY/ON key on the Control panel.
Note: The remote’s STANDBY/ON key won’t work after an
overtemperature condition until the power ON/OFF switch is
cycled and the lamp is turned on from the Control panel.
