Fixing Problems 60
If the red lamp light is flickering quickly:
• Check that the cover over the lamp at the side of the projector is correctly installed and
fully attached. Check the tab at the top of the cover and latch at the bottom.
Start-up problems
If no lights or sounds turn on:
• Be sure that the power cable is securely connected to the projector and the other end is
plugged into an outlet with power.
• Be sure the main disconnect switch is turned on.
• Press the power button again.
• Unplug the power cord for 15 seconds, then plug it in and press the power button
again.
Picture problems
If a “scanning” or “waiting” message is displayed on a blank screen:
• Press the source button on the projector or remote control one or more times until the
correct source name is selected.
• Be sure the external source is turned on and connected.
• For a computer connection, ensure your notebook computer’s external video port is
turned on. Refer to the computer manual. On some notebooks, for example, press the
F
N +F4 or F N +F5 function keys to turn on the external video port.
If the wrong input source is displayed:
• Press the source button on the projector or the remote control one or more times to select
another active input source.
If the image is out of focus:
• Be sure the lens cover is open.
• While displaying the on-screen menu, adjust the focus ring. (The image size should not
change; if it does, you are adjusting the zoom, not the focus.)
• Ensure the projection screen is 1 to 10 m (3 to 33 ft) from the projector.
• Check the projection lens to see if it needs cleaning.
