    usual•Check that the power cable is plugged in and that the power button on the
    projector cabinet or the remote control is on. See pages E-20 and E-21.
    •Ensure that the lamp cover or lamp housing is installed correctly. See page
    E-47.
    •Check to see if the projector has overheated or the lamp has reached the end
    of its usable life. If there is insufficient ventilation around the projector or if
    the room where you’re presenting is particularly warm, move the projector
    to a cooler location.
    •The lamp may fail to light. Wait a full minute and then turn on the power
    again.
    •The lamp has reached the end of its usable life. Replace the lamp.
    •Wait for 60 seconds (cooling period)to see if the lamp turns on by itself.
    POWER and STATUS LEDs blinking green at the same time indicates the
    main power was interrupted during previous operation.
    •Ensure that the Power Management is off. See page E-42.
    •Use the VIDEO, S-VIDEO, C-VIDEO or COMP. button on the remote control
    or the SOURCE button on the cabinet to select your source (Video, S-Video,
    Component or Computer). See page E-23.
    •Ensure your cables are connected properly.
    •Use menus to adjust the brightness and contrast. See page E-35.
    •Reset the settings or adjustments to factory preset levels using “Reset” in
    the menu. See page E-44.
    •Enter your registered keyword if the Security function is enabled. See page
    E-39.
    •When using with a notebook PC, be sure to connect between the projector
    and the notebook PC before turning on the power to the notebook PC. In
    most cases signal cannot be output from RGB output unless the notebook
    PC is turned on after connecting with the projector.
    *If the screen goes blank while using your remote control, it may be the
    result of the computer’s screensaver or power management software.
    *For more detailed, see page E-52.
    •Reposition the projector to improve its angle to the screen. See pages E-23
    and E-24.
    •Use the Keystone correction function to correct the trapezoid distortion. See
    page E-26.
    •Check if an appropriate color is selected in “Wall Color”. If so, select an
    appropriate option. See page E-35.
    •Adjust “Hue” in “Picture”. See page E-35.

    •Adjust the focus. See page E-26.
    •Reposition the projector to improve its angle to the screen. See pages E-23
    and E-24.
    •Ensure that the distance between the projector and screen is within the ad-
    justment range of the lens. See pages E-11 to E-14.
    •Condensation may form on the lens if the projector is cold, brought into a
    warm place and is then turned on. Should this happen, let the projector
    stand until there is no condensation on the lens.
    •Use the VIDEO, S-VIDEO, C-VIDEO or COMP. button on the remote control
    or the SOURCE button on the cabinet to select the source you want to input.
    •Adjust the computer image manually with the Horizontal /Vertical Position.
    See page E-37.
    •Connect a source the projector supports. See Compatible Input Signal List
    on page E-58.
    •Install new batteries. See page E-8.
    •Make sure there are no obstacles between you and the projector.
    •Stand within 22 feet (7 m) of the projector. See page E-9.
    •See the Power/Status/Lamp Indicator on page E-49.
    •Press the AUTO ADJ. button on the projector cabinet or the remote control.
    See page E-27.
    •Adjust the computer image manually with the Clock and Phase in “Image” of
    the menu. See page E-37.

    7. TROUBLESHOOTING
    If there is no picture, or the picture is not displayed correctly.
    •Power on process for the projector and the PC.
    Be sure to connect the RGB cable between the projector and the computer before turning on the computer.
    There are some notebook PCs, which do not output signal unless there is a projector or monitor connected
    first.
    NOTE: You can check the horizontal frequency of the current signal in the projector’s menu under Information. If it reads “0kHz”, this means there is no signal being output from the computer. See page E-43 or go to next step.
    •Enabling the computer’s external display.
    Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the
    projector. When using a PC compatible laptop, a combination of function keys will enable/disable the external
    display. Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external
    display to come on or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combi-
    nations to toggle through external display selections.
    •Non-standard signal output from the computer
    If the output signal from a notebook PC is not an industry standard, the projected image may not be displayed
    correctly.
    Should this happen, deactivate the notebook PC’s LCD screen when the projector display is in use. Each
    notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the previous
    step. Refer to your computer’s documentation for detailed information.
    •Image displayed is incorrect when using a Macintosh
    When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the
    projector) according to your resolution. After setting, restart your Macintosh for the changes to take affect.
    For setting display modes other than those supported by your Macintosh and the projector, changing the DIP
    switch on a Mac adapter may bounce an image slightly or may display nothing. Should this happen, set the
    DIP switch to the 13 fixed mode and then restart your Macintosh. After that, restore the DIP switches to a
    displayable mode and then restart the Macintosh again.
    NOTE: A Video Adapter cable manufactured by Apple Computer is needed for a PowerBook which does not have a mini D-Sub 15-pin connector.
    •Mirroring on a PowerBook
    *When using the projector with a Macintosh PowerBook, output may not be set to 1024 x 768 unless “mirror-
    ing” is off on our PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.
    •Folders or icons are hidden on the Macintosh screen
    Folders or icons may not be seen on the screen. Should this happen, select [View] → [Arrange] from the Apple
    menu and arrange icons.
