Lamp outTake out the lamp and check if it is broken. Replacing the Lamp   p.126
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.
Internal temperature error  
(overheating)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.   p.16
 If the air filters are blocked, clean or replace them.   p.124
When the power cable is plugged back in, the projector will return to its previous state, so press 
the [Power] button on either the projectors 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 
Te r m s booklet.
High-speed cooling in progress (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.   p.16
 If the air filters are blocked, clean or replace them.   p.124
Lamp replacement notification Replace the lamp with a new one.   p.126
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.
