If the red lamp light is flickering quickly:
• Check that the cover over the lamp is correctly installed and fully attached.
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.
• 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 FN+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 removed.
• 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 1.5 to 10 m (5 to 33 ft) from the projector.
• Check the projection lens to see if it needs cleaning.
• For a computer connection, set the display resolution as the computer to the same
resolution as the projector, 1024 × 768 (see “Specifications” on page 55). If the
computer has multiple monitors, adjust the resolution of the monitor assigned to the
projector.
• For a computer connected to the S-video port, the picture cannot be as high resolution
as what you see on the computer display.
