Maintenance Indicators
Info
If the TEMPERATURE WARNING indicator illuminates, and the power turns off, follow the above possible
solutions and then wait until the projector has cooled down completely before plugging in the power cord and
turning the power back on. (At least 5 minutes.)
If the power is turned off and then turned on again, as during a brief test, the LAMP REPLACEMENT indica-
tor may be triggered, preventing the power from going on. Should this occur, take the power cord out of the
wall outlet and plug it back in again.
If you want to clean the air vents during projector operation, be sure to first press 
 and after the power has
turned off and the cooling fan has stopped, then clean the vents.
Do not unplug the power cord after the power has been turned off and while the cooling fan is running. The
cooling fan runs for about 90 seconds.
About the TEMPERATURE WARNING indicator
If the temperature inside the projector in-
creases, due to blockage of the air vents, or
the setting location, “
” will blink in the
lower left corner of the picture. If the tem-
perature keeps on rising, the lamp will turn
off and the TEMPERATURE WARNING in-
dicator will blink, the cooling fan will run for
further 90 seconds, then the power will be
shut off. After “
” appears, be sure to
perform the following measures.
I The warning lights on the projector indicate problems inside the projector.
I If a problem occurs, either the TEMPERATURE WARNING indicator or the LAMP REPLACEMENT
indicator will illuminate red, and the power will turn off. After the power has been turned off, follow
the procedures given below.
