Take out the lamp and check if it is broken. Replacing the Lamp
If the lamp is not broken, put it back in and then turn the power on. If the lamp still does not turn
on, replace it with a new lamp.
If this does not solve the problem, stop using the projector and disconnect the power cable from
the electrical outlet. Then contact your dealer or the nearest address provided in the "International
Warranty Conditions" section of the Safety Instructions/World-Wide Warranty Terms booklet.
If the lamp is broken.
Contact your local dealer for further advice.
(Projection cannot be carried out until the lamp is replaced.)
Check that the lamp and the lamp cover are securely installed. If the lamp or lamp cover is not
securely installed, the lamp will not switch on.
The lamp will turn off automatically and projection will stop. Wait for about 5 minutes without
operating the projector. After about 5 minutes have elapsed, unplug the power cable and then
check the following two points.
•Check that the air filter and air exhaust vent are clear, and that the projector is not positioned
against a wall.
•If the air filters are blocked, clean or replace them.
When the power cable is plugged back in, the projector will return to its previous state, so press
the [Power] button on either the projector's control panel or the remote control 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, disconnect
the power cable from the electrical outlet, and contact your dealer or the nearest address provided
in the "International Warranty Conditions" section of the Safety Instructions/World-Wide Warranty
Terms booklet.
(This is not an abnormality, However, if the temperature rises too high again, projection will stop
automatically.)
•Check that the air filters and air exhaust vent are clear and that they are not up against a surface
such as a wall.
•If the air filters are blocked, clean or replace them.
Replace the lamp with a new one.
If you continue to use the lamp after it has passed the replacement period, the possibility that the
lamp may break will increase. Replace the lamp with a new one as soon as possible.
* The indicator status will vary depending on the projector status at the time.
