• Check that the power cable is plugged in, the main power switch is on, and that the power button on the

cabinet or the remote control is on.

• Ensure that the lamp cover is installed correctly. See page E-36.

• Check to see if the rear projection display has overheated or the lamp usage exceeds 2100 hours (3150

hours in Eco mode). If there is insufficient ventilation around the rear projection display or if the room where

you're presenting is particularly warm, move the rear projection display to a cooler location.
