Power failure and fan lock detection

The projector provides the detection circuits of the power failure and the fan lock. When the detection circuit detects
an error at the power supply line or at the fan operation 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 lighting
and other indicators are blinking.
When the projector detects an abnormal condition (Power supply lines failure
or fans failure), it will be automatically shut down to protect the inside of the
projector and the LAMP indicator lights on and other indicators 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.
