■

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 124.

■

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.

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 73).
