Shutting down the projectorThe projector automatically blanks the screen after no active source is 
detected for 30 minutes. This blank screen helps preserve the life of the pro-
jector. The image returns when an active source is detected or a remote or 
keypad button is pressed. The Interactive Display on the projector indicates 
the shutdown status.
Screen Save
You can make the blank screen appear after five minutes by turning on 
Screen Save in the Settings>System menu. See page 33. There are six time 
options for the Screen Save feature. They range from five minutes to 30 min-
utes with five minute intervals.
Pow e r  S av e
The projector also has a Power Save feature that automatically turns the 
lamp off after no signals are detected for 5 minutes. After 3 additional min-
utes with no signal, the projector powers down. If an active signal is 
received before the projector powers down, the image is displayed. You 
must press the Pow e r button to display an image after 30 minutes have 
passed. When Power Save is enabled, Screen Save is disabled. See page 33.
Turning off the projector
To turn off the projector, press the Powe r button and verify that you want to 
turn the projector off by pressing the Powe r button again within 3 seconds. 
You can cancel the shutdown by not pressing the Pow e r button a second 
time. The lamp turns off and the LED blinks green for 1 minute while the 
fans continue to run to cool the lamp. When the lamp has cooled, the LED 
lights green and the fans stop. Unplug the power cable to completely power 
off the projector.
Troubleshooting your setupIf your image appears correctly on the screen, skip to the next section 
(page 25). If it does not, troubleshoot the setup. The Interactive Display and 
LED on top of the projector indicate the state of the projector and can help 
you troubleshoot. 
 
The following tables show common problems. In some cases, more than one 
possible solution is provided. Try the solutions in the order they are pre-
sented. When the problem is solved, you can skip the additional solutions.
