Problem Solving
Cause and solution
The projector is too hot, which turns off the lamp automatically.
Let it cool for five minutes, then turn it back on. Make sure there
is plenty of space around and under the projector for ventilation.
Also, clean or replace the filter if necessary (see page 48).
If you are using the projector at an altitude above 4900 feet (1500
meters), turn on High Altitude Mode so the fan can properly cool
the projector at the high altitude air pressure (see page 46).
The lamp needs to be replaced (see page 50). Make sure you
have a spare lamp handy. Check to make sure the lamp and lamp
cover are securely installed.
There is an internal problem. Turn off the power switch on the
back of the projector, and unplug it from the electrical outlet.
Then contact Epson for assistance (see page 60).
