Solving Projector Operation Problems

The power doesn't turn on.
If the projector doesn't turn on when you press the Ppower
■
button, make sure the power cord is connected to the projector
and plugged into a working electrical outlet.
The power cord may be defective. Disconnect the cord from the
■
outlet and contact Epson as described on page 97.
If you're using the Direct Power On function and you
■
immediately plug the power cord back in after unplugging it, the
power may not turn back on. Press the Ppower button to turn
the projector back on.
The buttons on the projector don't work.
If the Control Panel Lock function has been enabled, you can't use the
buttons on the projector. Try using the remote control instead (make
sure it is set to the correct ID). See page 66 for information about the
Control Panel Lock function.
Description
The lamp may be burnt out. First make sure the lamp cover is
securely installed. If that's not the problem, the air filter may be
clogged. Clean or replace the air filter as described on pages 74
to 78.
If this does not resolve the problem, let the lamp cool and then
remove it. If the lamp is cracked, replace it as described on page 78.
If the lamp is not cracked, reinstall it. If reinstalling doesn't work,
replace the lamp.
If you're using the projector above an altitude of 4,900 feet (1,500
meters), turn on High Altitude Mode in the Operation menu (see
page 67).
If none of these suggestions resolves the problem, contact Epson as
described on page 97.
