Turn off the projector and unplug the power cable. Wait 60 minutes to allow the projector to cool thoroughly. Turn the projector upside down and remove the lamp door by removing the two screws and sliding the lamp door tabs out of the two tab bays.
To reset the lamp timer, press the decrease volume button on the keypad and then the increase volume button within 3 seconds. A t that point the L E D will turn green and you can power on the projector. You can also navigate to the Settings>Service menu and select Lamp Reset to reset the lamp timer.
