Troubleshooting
High temperature
inside projector
(overheating)
The lamp will turn off automatically and projection will stop.
Wait for about 5 minutes without operating the projector. After 5
minutes have elapsed, the projector's cooling fan will stop. When
the cooling fan stops, turn off the main power switch and then
turn it back on again.
If the projector overheats, check the following two points.
•
••
•
Is the setting-up location well ventilated?
Check that the air inlet and air outlet are clear, and that the
projector is not positioned against a wall.
•
••
•
Is the air filter blocked with dust?
If the air filter is dirty, it should be cleaned.
When the main power switch is turned back on, the projector will
return to its previous state, so press the [
STANDBY/ON
] button
on either the remote control or the projector's control panel to turn
it back on. If the projector continues to overheat even after the
above points have been checked, or if the indicators show a
problem when the power is turned back on, stop using the
projector, turn off the main power switch, disconnect the power
cord from the electrical outlet, and contact your dealer.

(This is not an abnormality, but if the temperature rises too high
again, projection will stop automatically.)
•
••
•
Set the projector up in a place which is well-ventilated, and so
that the air inlet and exhaust vents are clear.
•
••
•
Clean the air filter.

Lamp will soon need
to be replaced.
(No abnormality)
Have a new replacement lamp ready.
The lamp service life can become shorter than normal as a result
of the usage conditions, and so the lamp should be replaced as
soon as possible.
* The appearance of the indicator at this time will vary
depending on the status of the projector.

Standby condition (No abnormality)

Cool-down in
progress
(No abnormality)
•
••
•
Wait for a short while.
The cool-down
(lamp cooling operation) period lasts for
about 5 minutes. The actual time will vary depending on factors
such as the ambient air temperature.
•
••
•
The [STANDBY/ON] buttons on both the projector's control
panel and the remote control will not operate while the
indicator is flashing red. When the indicator changes to
flashing orange (after approximately 90 seconds), the
[STANDBY/ON] buttons on the projector's control panel and
the remote control will then work.
•
••
•
If the main power switch at the rear of the projector is turned
off before cool-down is complete, wait for the lamp to cool
down (normally about one hour is required) before turning the
power back on again.
