    let you know when a problem occurs.
    If the projector is not working correctly, first turn it off and unplug it. 
    Then plug the power cord back in and turn on the projector. If this 
    does not solve the problem, check the status lights on top of the 
    projector and try the solutions recommended in the following table.

    Solving Problems with the Image or 
    Sound
    No image appears on the screen.
    ■Check that the power light is green, not flashing, and the lens cap 
    is off. 
    ■The projector may be in standby or sleep mode. If the projector 
    has not received any input signal for 30 minutes, it turns off the 
    lamp to conserve the lamp life and save energy. If the power light 
    is orange, press the P 
    Power button to turn the projector on.
    ■Press the A/V Mute button to make sure the picture has not been 
    turned off temporarily. 
    ■If the power was switched off and then on again, the projector 
    may still be cooling down. Wait until the power light stops 
    flashing and remains orange; then press the P 
    Power button 
    again.
    ■Check the Video Signal or Input Signal setting in the Image 
    menu to make sure it is correct for the selected source. See 
    page 50 for more information.

    Nothing appears on the external monitor.
    ■Make sure the VGA computer cable is connected to your 
    computer’s video port and the projector’s 
    Computer1/Component Video1 port. It will not work if you 
    connected the computer cable to the projector’s 
    Computer2/Component Video2 port.
    ■Make sure the cable from your monitor is connected to the 
    projector’s 
    Monitor Out port.
    You see a blue screen with the message No Signal displayed.
    ■Make sure the cables are connected correctly, as described in

    ■Make sure the power to your computer or video source is turned 
    on.
    ■If you’ve connected a computer and one or more video sources, 
    you may need to press the 
    Source button (on the projector) or 
    the 
    Computer1/2 or S-Video/Video button (on the remote 
    control) to select the correct source. Allow a few seconds for the 
    projector to sync up after pressing the button.
    ■If you’ve connected a laptop computer, make sure it’s set to 
    display on an external monitor. See page 31. 
    If you’re using a PC laptop:
    ■Hold down the Fn key and press the function key that lets you 
    display on an external monitor. It may have an icon such as

    CRT/LCD. Allow a few seconds for 
    the projector to sync up after pressing it. Check your laptop’s 
    manual or online help for details. 
    On most systems, the   or 
    CRT/LCD key lets you toggle 
    between the LCD screen and the projector, or display on both at 
    the same time.  
    						
    							Solving Problems77
    ■Depending on your computer’s video card, you might need to use 
    the Display utility in the Control Panel to make sure that both the 
    LCD screen and external monitor port are enabled. See your 
    computer’s documentation or online help for details.

    ■Make sure your computer’s resolution doesn’t exceed UXGA and 
    the frequency is supported by the projector. See page 88. If 
    necessary, change your computer’s resolution setting as described 
    below. 
    ■Make sure the correct Video Signal is selected in the Image 
    menu. See page 50. It should normally be set to 
    Auto.

    Only part of the computer image is displayed.
    ■You may need to adjust the Position setting in the Image menu. 
    See page 49 for more information.
    ■If you changed the Aspect Ratio setting for a different source, you 
    may need to change it back to 4:3. See page 50 for instructions.
    ■Make sure your computer’s resolution setting is correct. Ideally, 
    it should be 1024 
    × 768 (for the PowerLite 74c) or 800 × 600 
    (for the PowerLite 54c) to match the projector’s native resolution.

    resolution. 
    ■You also may need to modify existing presentation files if you 
    created them for a different resolution. See your software 
    documentation for specific information.
    ■If you used the E-Zoom feature, press Esc on the remote control 
    to cancel zooming and return to full screen size.
    The image isn’t rectangular, but trapezoid-shaped.
    ■Make sure the projector isn’t placed off to one side of the screen, 
    at an angle, or the image won’t be rectangular. Place it directly in 
    front of the center of the screen, facing the screen squarely.
    ■If you’ve tilted the projector upward, the image will be broader at 
    the top. Turn on Auto Keystone correction as described on 
    page 52 or hold down the   or   side of the 
    Keystone 
    button on top of the projector until the image is rectangular. 
    						
    							Solving Problems79
    The image contains static or noise.
    ■If you’re using a computer cable longer than 6 feet, or an 
    extension cable, the image quality may be reduced.
    ■Keep your computer and video cables separated from the power 
    cord as much as possible to prevent interference.
    ■The video signal may be split between the computer and the 
    projector. If you notice a decline in the projected image quality 
    when the image is displayed simultaneously on your laptop 
    computer and the projector, turn off the laptop’s LCD display.
    ■Check the Input Signal or Video Signal setting in the Image 
    menu.
    ■Make sure the cables are securely connected.
    ■Select the correct resolution; see “Compatible Video Formats” on 
    page 88.
    ■Try adjusting the Sync and Tracking settings in the Image 
    menu.
    The image is blurry.
    ■Adjust the focus using the focus ring.
    ■Make sure the lens cap is off.
    ■There may be dirt or smears on the lens. Clean the lens as 
    described on page 64.
    ■Make sure the lens is not fogged by condensation. You may need 
    to wait before using the projector after moving it from a cold 
    environment.
    ■Make sure the projection distance is within the range described on 
    page 14.
    ■Adjust the Sharpness setting on the Image menu (see page 49). 
    You should be able to see the effect on the screen immediately. 
    If you’re projecting from a computer, you may also need to adjust 
    the 
    Tracking and Sync as described in the next section. If you 
    don’t like the new settings, you can always select 
    Reset to return 
    to the factory default settings. 
    						
    							80Solving Problems
    You see vertical stripes or the image still looks blurry after 
    trying the solutions in the previous section.
    ■If you’re projecting from a computer and displaying an image that 
    contains a lot of fine detail, you may notice one or more vertical 
    stripes or bands, or some of the characters may look heavy or 
    blurred. Press the 
    Auto button on the remote control. This resets 
    the projector’s tracking and sync settings.
    ■If further adjustment is needed, you can fine-tune the Tracking 
    and 
    Sync settings manually using the Image menu as described 
    on page 49. 
    1. Fill the screen with an image containing fine detail when 
    making these adjustments. For example, in Windows you can 
    select a pattern to appear as your desktop background. Or try 
    projecting black text on a white background.
    2. Adjust the 
    Tracking to eliminate vertical stripes. 
    3. Adjust the 
    Sync to increase the sharpness of the image.
    The colors of the image are not right.
    ■Try selecting a different Color Mode. 
    ■If you’re displaying video, adjust the Color and Tint settings on 
    the Image menu. See page 48 for instructions.
    ■Adjust the Brightness and Contrast settings on the Image 
    menu.
    ■Try adjusting the Color Adjustment setting on the Advanced 
    menu.
    ■If the images appear too green or too purple, check that the 
    Input Signal or Video Input setting is correct on the Image 
    menu.
    ■Check your computer display settings to correct the color balance.
    ■If the image seems dark, the lamp may be nearing time for 
    replacement. Check the lamp hours as described on page 55 and 
    replace it, if necessary, as described on page 67.
    note
    Because of the different 
    technologies used, your 
    projected image may not 
    exactly match the colors on 
    your laptop or computer 
    monitor.
