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 FN+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. 50 Fixing Problems
