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 all indicators are blinking.
When the projector detects an abnormal condition (Power supply lines failure , fans failure), it will be automatically
shut down to protect the inside of the projector and all of 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 blinking, the projector may has an internal error. Unplug the AC power cord. See the troubleshoot-
ing chapter.
WARNING
DO NOT LEAVE THE PROJECTOR WITH THE AC POWER CORD CONNECTED UNDER AN
ABNORMAL CONDITION. IT MAY RESULT IN FIRE OR ELECTRIC SHOCK.
