the cable’s green connectors into the green component-out connector on the 
video device and into the green component connector (labeled “Y”) on the 
projector. Plug the component cable’s blue connectors into the blue compo-
nent-out connector on the video device and into the blue component con-
nector (labeled “Pb”) on the projector. Plug the component cable’s red 
connectors into the red component-out connector on the video device and

Shutting down the projectorThe projector automatically displays a black screen after no active source is 
detected for 30 minutes. This black 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.Screen SaveYou can make the black screen appear after five minutes by turning on 
Screen Save in the Settings>System menu. See page 32. 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 aveThe projector also has a Power Save feature that automatically turns the 
lamp off after no signals are detected for 20 minutes. After 10 additional 
minutes 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 Power button to display an image after 30 minutes have 
passed. When Power Save is enabled, Screen Save is disabled. See page 31.Turning off the projectorTo turn off the projector, press the power button and verify that you want to 
turn the projector off by pressing the power button again within 3 seconds. 
You can cancel the shutdown by not pressing the power 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 23). If it does not, troubleshoot the setup. 
The LED on top of the projector’s keypad indicates 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.
