Solutions to Projector Power or Shut-Off Problems
If the projector does not turn on when you press the power button or it turns
off unexpectedly, try the following solutions:
• Make sure the power cord is securely connected to the projector and to a
working electrical outlet.
• If the power button on the remote control does not turn on the projector,
check its batteries and make sure at least one of the remote receivers are
available in the Remote Receiver setting in the projector's Settings menu.
• The projector's buttons may be locked for security. Unlock the buttons in
the Control Panel Lock setting or use the remote control to turn on the
projector.
• If the projector's light source turns off unexpectedly, it may have entered
sleep mode after a period of inactivity. Perform any operation to wake the
projector. To turn off sleep mode, set the Sleep Mode setting to Off.

• If the projector turns off unexpectedly, the A/V mute timer may be enabled
(EB‑PU2120W). To turn off the A/V mute timer, set the A/V Mute Timer
setting to Off.

to Off.

• If the projector's light source turns off, the status indicator is flashing, and
the temp (temperature) indicator is lit, the projector has overheated and
turned off.
• The cooling fans may run in standby status depending on the projector
settings. Also, when the projector wakes from standby status, the fans may
cause an unexpected noise. This is not a malfunction.
• The power cord may be defective. Disconnect the cord and contact Epson
for help.
Solutions to Problems with the Remote Control
If the projector does not respond to remote control commands, try the
following solutions:
• Check that the remote control batteries are installed correctly and have
power. If necessary, replace the batteries.
• Make sure you are operating the remote control within the reception angle
and range of the projector.
• Make sure the projector is not warming up or shutting down.
• Check to see if a button on the remote control is stuck down, causing it to
enter sleep mode. Release the button to wake the remote control up.
• Strong fluorescent lighting, direct sunlight, or infrared device signals may be
interfering with the projector's remote receivers. Dim the lights or move the
projector away from the sun or interfering equipment.
• Make sure at least one of the remote receivers are available in the Remote
Receiver setting in the projector's Settings menu.
• If you enabled the remote control button lock, press and hold the [Home]
button for about 5 seconds to turn it off.
• If you assigned an ID number to the projector to operate multiple projectors
from the remote control, you may need to check or change the ID setting.
• Set the remote control [ID] switch to Off. You can operate all of the
projectors regardless of the projector ID settings.
