Communication On and make sure the A/V Settings options are set correctly.

Solutions to Projector Power or Shut-Off Problems
If the projector does not come on when you press the power button or it shuts off unexpectedly, try the
following solutions:
• Make sure the power cord is securely connected to the projector and to a working electrical outlet.
• The projector's buttons may be locked for security. Unlock the buttons or use the remote control to
turn on the projector.
• If the projector's lamp shuts off unexpectedly, it may have entered standby mode after a period of
inactivity. Press the power button to wake the projector and adjust the Sleep Mode Timer setting to
change the sleep interval.
• If the power button on the remote control does not turn on the projector, check its batteries and make
sure the Remote Receiver setting is turned on in the projector's menu, if available.
• The power cord may be defective. Try another power cord. If that doesn't work, disconnect the cord
and contact Epson.
