When the temperature inside the projector reaches a

operating temperature), it can be turned on again by
pressing the ON/STAND-BY button.

even after the temperature inside the projector returns
to normal. When the projector is turned on again, the
WARNING TEMP. 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 the air
vents of the projector are not blocked.
– Has the projector been installed near an Air-Conditioning/
Heating Duct or Vent? Move the installation of the
projector away from the duct or vent.
– Is the filter clean? Replace the filter with a new one.

of the projector and the LAMP/SHUTTER 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 and
contact the service center.
