• Check that the power cable is plugged in and that the power button on the projector cabinet or the remote
control is on. See pages 29 and 31 .
• Ensure that the lamp cover is installed correctly. See page 136 .
• Check to see if the projector has overheated or the lamp usage exceeds 2100 hours (up to 4100 hours : Eco
mode). If there is insufficient ventilation around the projector or if the room where you’re presenting is par-
ticularly warm, move the projector to a cooler location.
• If you turn on the projector immediately after the lamp is turned off or when the temperature is high, the fans
run without displaying an image for some time and then the projector will display the image. Wait for a
moment.
• The lamp may fail to light. Wait a full minute and then turn on the power again.
• The lamp has reached the end of its usable life. Replace the lamp. See page
134 .
After replacing the lamp, press and hold the HELP button on the remote control for a minimum of 10 seconds
to clear the lamp usage time. This will allow you to turn on the projector.
• Ensure that the Power Management is off. See page 120 .
• Use the SOURCE button on the projector cabinet or the COMPUTER, VIDEO or VIEWER button on the remote
control to select your source. See page 40 .
• Ensure your cables are connected properly.
• Use menus to adjust the brightness and contrast. See page
88 .
• Open the mirror cover. See page 6 .
• Reset the settings or adjustments to factory preset levels using the Reset in the Menu. See page 129 .
• Enter your registered keyword if the Security function is enabled. See page 60 .
• When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning
on the power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook
PC is turned on after connecting with the projector.
* If the screen goes blank while using your remote control, it may be the result of the computer's screen-
saver or power management software.
* If you accidentally hit the POWER button on the remote control, wait 90 seconds and then press the POWER
button again to resume.
