The lamp will turn off automatically and projection will stop. Wait for about 5 minutes until the projector
switches to standby mode, then do the following:
• Make sure the air filter and air exhaust vent are clear, and the projector is not positioned against a wall.
• If the air filters are blocked, clean or replace them. See page 44
.
Press the [Power] button to turn the power back on. If this does not solve the problem and the projector
continues to overheat or the indicators continue to show a problem when the power is turned on, stop using
the projector, disconnect the power cable from the wall outlet, and contact Epson (see page 57
).
Lamp problem
Lamp timer failure
Lamp cover is open
Take out the lamp and check if it is broken. See page 41.
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 Epson (see page 57
).
If the lamp is broken replace it with a new lamp, or contact Epson for further advice (see page 57). If
replacing the lamp yourself, be careful to avoid pieces of broken glass. (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.
When using above an altitude of about 1,500m, make sure you set the "High Altitude Mode" to
"On".
