Check These Items
• Check that the power cable is plugged in and that the main power switch on the projector is on. See pages E-
27 and E-30.
• Ensure that the lamp cover is installed correctly.
• Check to see if the projector has overheated or the lamp has reached the end of its usable life. If there is
insufficient ventilation around the projector or if the room where you're presenting is particularly warm, move
the projector to a cooler location.
• 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.
• Ensure that the off Timer is off. See page E-67.
• Use the menu or Source/Input button to select your source. See page E-31 or E-50.
• Ensure your cables are connected properly.
• Use menus to adjust the brightness and contrast. See page E-51.
• Select correct option in the Signal Select for current signal. See page E-60.
• Select RGB/Component when connecting DVD player to RGB connector of the projector. See page E-60.
• Apply a standard RGB signal when using RGB connector.

• 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.
• Reposition the projector to improve its angle to the screen. See page E-31.
• Use the 3DReform function to correct the trapezoid distortion. See page E-55.
• Adjust the focus. See page E-32.

• Ensure that the distance between the projector and screen is within the adjustment range of the lens. See page
E-22.

Should this happen, let the projector stand until there is no condensation on the lens.

input. See page E-31 or E-50.

wirelessly. See page E-20.
