Solving Projector Operation Problems
The power doesn’t turn on.
■ If the projector doesn’t turn on when you press the
P
power
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 78.
■ 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
P
power 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, or
press and hold the projector’s
Enter
button for seven seconds to
release the lock (see page 55).
Solving Problems With the Image

■
Check that the

A/V Mute

A/V Mute
button on the

temporarily.

The projector may be in standby or sleep mode. If the

light is orange, press the

If the power was switched off and then on again, the projector
may be cooling down. Wait until the
P
power light stops flashing
and remains orange; then press the
