Do you hear the fan start up? or does the projector lamp come on (you start to see an image)?
If yes to either:
When the temperature inside the projector reaches a
certain level, the projector will be automatically shut down
to protect the inside of the projector. The POWER indicator
is blinking while the projector is being cooled down. When
the projector has cooled down sufficiently (to its normal
operating temperature), it can be turned on again by
pressing the POWER ON-OFF button.
After the temperature inside the projector returns to normal, the
WARNING indicator still continues to blink. When the projector is
turned on again, the WARNING indicator stops blinking.
Then check the matters below:
– Did you provide appropriate space for the projector to be
ventilated? Check the installing condition to see if
ventilation slots are not blocked.
– Is the projector not installed near the ventilation duct of
air-conditioning equipment which may be hot? Install the
projector away from the ventilation duct of airconditioning
– Are the air filters clean? Clean the air filters periodically. Let me know if you need to know how to do this.
If no to either:
When the projector detects an abnormal condition, it is
automatically shut down to protect the inside and the
WARNING indicator will be red. In this case, disconnect the
AC power cord and reconnect it, and then turn the projector
on once again for check. If the projector cannot be turned
on and the WARNING indicator emits a red light, disconnect
the AC power cord and contact the service station for check
Please let me know if this helped solve the problem. If not, is there anything else you observed - whether or not you believe it's relevant.
