    When Having Some Trouble
    If you are having a problem with the projector, first check the projectors 
    indicators.
    The projector is provided with the following two indicators. These indicators 
    alert you to problems with projector operation.
    The following tables show what the indicators mean and how to remedy 
    problems that they indicate.

    High internal 
    temperatureThe lamp will turn off automatically and 
    projection will stop. Wait for about 5 minutes 
    without operating the projector. After 5 minutes 
    have elapsed, unplug the power cord and then plug 
    it back in again. 
    If the projector overheats, check the following two 
    points.
    Check that the air inlet and air outlet are clear, 
    and that the projector is not positioned against a 
    wall.
    If the air filter is dirty, it should be cleaned.
    When the power cord is plugged back in, the 
    projector will return to its previous state, so press 
    the [Power] button on either the projectors control 
    panel or the remote control to turn it back on. If 
    the projector continues to overheat even after the 
    above points have been checked, or if the 
    indicators show a problem when the power is 
    turned back on, stop using the projector, 
    disconnect the power cord from the electrical 
    outlet, and contact your dealer or the nearest 
    address provided at “International Warranty 
    Conditions” in Safety Instructions/ World-Wide 
    Warranty Terms.

    Problem with 
    lampDisconnect the power cord from the electrical 
    outlet and then remove the lamp and check if it is 
    broken. If the lamp is not broken, reinstall it. If the 
    lamp is broken, replace it. Then reconnect the 
    power cord and press the [Power] button on either 
    the projectors control panel or the remote control 
    to turn the power back on.
    If the indicators still show a problem, stop using 
    the projector, disconnect the power cord from the 
    electrical outlet, and contact your dealer or the 
    nearest address provided at International 
    Warranty Conditions in Safety Instructions/
    World-Wide Warranty Terms.
    78
    If the lamp is broken, remove it while being very 
    careful not to injure yourself on the broken edges, 
    and replace it with a new lamp. (Projection cannot 
    be carried out until the lamp is replaced.)
    78
    Check that the lamp and the lamp cover are 
    securely installed. If the lamp or lamp cover is not 
    securely installed, the lamp will not switch on.78

    Tip :
     If the projector is not operating properly even though the indicators are all showing 
    normal, refer to When the Indicators Provide No Help on the following page.
     If an indicator is showing a status which does not appear in the previous tables, 
    contact your dealer or the nearest address provided at International Warranty 
    Conditions in Safety Instructions/ World-Wide Warranty Terms.
    Internal problem Stop using the projector, disconnect the power 
    cord from the electrical outlet, and contact your 
    dealer or the nearest address provided at 
    “International Warranty Conditions” in Safety 
    Instructions/ World-Wide Warranty Terms.
    High-speed 
    cooling in 
    progress(This is not an abnormality, but if the temperature 
    rises too high again, projection will stop 
    automatically.)
    Set the projector up in a place which is well-
    ventilated, and so that the air filter and exhaust 
    vents are clear.
    Clean the air filter.

    again?
    After the power is turned off (during cool-down
    ), the 
    [Power] buttons on the projectors control panel and the 
    remote control will not work. Wait until cool-down has 
    finished. You can then use the [Power] buttons. (p.31)
    Is sleep mode active?
    When sleep mode has been set to ON, the lamp turns off 
    automatically if no operations are carried out for 30 
    minutes while no image signal is being input. The Power 
    indicator lights orange at this time.

    Blue for messages to be displayed. If a message is 
    displayed, refer to the item indicated.

    Check the mode which corresponds to the frequency 
    of the image signals being output from the computer.
    Refer to the documentation provided with your computer 
    for details on changing the resolution and frequency of the 
    image signals being output from the computer. (p.90)
    Are the cables connected correctly?
    (p.17 - p.25)
    Does the input signal match the connected source?
    Use the [Source] button on the projectors control panel (or 
    the [Computer] or [S-Video/ Video] button on the remote 
    control) to select the correct signal source. (p.30)
    Is the power for the computer or video source turned 
    on? (p.29)
    If a laptop computer or a computer with a LCD screen 
    has been connected to the projector, it is necessary to 
    output the image signals to the projector rather than 
    to the screen.
    Normally image signals are output to only the computers 
    LCD screen, so you need to change the output to an 
    external destination. For some computer models, when the 
    image signals are output externally, they no longer appear 
    on the LCD screen. For details, refer to the section of the 
    documentation provided with your computer under a 
    heading such as External output, Connecting an external 
    monitor or similar. (p.30)

    Poor image quality
    Has the focus been adjusted correctly? 
    (p.37)
    Has the front adjustable feet been adjusted so that the 
    image angle is too big?
    If the image angle is too big, the image will be out of focus 
    vertically. (p.34)
    Is the projector at the correct distance?
    The recommended distance from the projector to the screen 
    is within 1.0 - 11.7 m (3.2 - 38.5 ft.). Set up the projector so 
    that the projection distance is within this range. (p.15)
    Is the projector beam perpendicular to the screen?
    (p.34)
    Is the lens dirty?
    (p.74)
    Has condensation formed on the lens?
    If the projector is suddenly taken from a cold environment 
    to a warm environment, condensation may form on the 
    surface of the lens, and this may cause the images to appear 
    fuzzy. Set the projector up in the room approximately one 
    hour before it is to be used. If condensation forms on the 
    lens, turn off the power and wait for the condensation to 
    disappear.
    Have the Sync
    .,  Tracking and Position been 
    adjusted correctly?
    If the Auto Setup command in the Video menu is set to 
    OFF, press the [Auto] button on the remote control to 
    adjust these settings. If the images have not been correctly 
    adjusted after using the automatic setup function and after 
    pressing the [Auto] button, adjust the settings manually 
    using the respective menus.
    (p.38, 49)
    Are the image signal format settings correct?
    If a computer, component video
      or RGB-Video source is 
    connected to the projector, use the Input Signal command 
    in the Video menu to select the signal format which 
    matches the signal connected source. (p.49, 50)
    If a composite video
     or S-Video source is connected to 
    the projector, use the Video Signal command in the 
    Video menu to select the video signal format. (p.51)
