Power failure, fan lock and filter error detection

The projector provides the detection circuits of the power failure, the fan lock and the AMC filter error. When the de-
tection circuit detects an error at the power supply line, at the fan operation circuit or at the AMC filter control circuit,
the projector will turn into the standby mode to protect the other circuits defective.
the projector is shut down; and the LAMP indicator is light-
ing and other indicators are blinking.
When the projector detects an abnormal condition (Power supply lines failure
, fans failure or AMC filter failure), it will be automatically shut down to protect
the inside of the projector and the LAMP indicator lights on and other indica-
tors blink. In this case, unplug the AC power cord and plug it, and then turn on
the projector once again to verify operation. If the projector cannot be turned
on and these indicators are still lighting and blinking, unplug the AC power
cord. See the troubleshooting chapter.
