the power cord from the wall outlet. Then plug the power cord back in
and turn on the projector. If this does not solve the problem, check the
warning lights at the top of the projector. These lights alert you to
problems with projector operation.

Problems with the Image or Sound
 An image does not appear on the screen.
Check that the power light is on and the lens cover is off. Also make
sure the cables are installed correctly, as described in Chapter 1.
The correct image source may not be selected. Press the Source button
on the remote control or the control panel to choose the other image
source.
Only part of the computer image is displayed.
If the computer’s output resolution setting is set higher than 640 x
480, the projector resizes the image. If the computer output is not
compatible with this resizing, choose a different display setting on the
computer. In Windows 3.1, use Windows Setup in the Main program
group. For a Macintosh, choose Control Panels under the Apple menu525 l Troubleshooting 
						

							and then Monitors; in the Monitors screen, choose Options and make
sure Macintosh Hi-Res Display or another 640 x 480 display is
selected. For supported display settings, see Chapter 6.
If a 640 x 480 display is selected, see Chapter 6 for supported display
settings. You also may need to modify existing presentation files if you
created them for a different resolution. See your software manual for
specific information.
The message NO SIGNAL is displayed.
An image source not connected to the projector is selected, the signal is
not being output from the computer, or the signal is not reaching the
projector. Make sure the connectors are securely attached to both the
projector and the image source. Then check that the image source is
selected correctly. When NO SIGNAL is displayed, you cannot access
the projector menus.
A black screen is displayed.
The computer signal cannot be interpreted by the projector. Verify the
display format (see page 57). When you see a black screen, you cannot
access the projector menus.
The image or parts of the image are blurred or not in focus.
Turn the focus ring on the projector to see if this improves the image.
Also check that the projector is within the recommended distance for
the size of the screen. (See the table on page 4 for more information.)
For the sharpest images, the projector must be perpendicular to the
screen and the projection surface must be flat.
Problems with the Image or Sound53

Video Image main menu. If you’re viewing a computer image, also try
adjusting the Comp Tracking and Comp Sync buttons on the
projector’s control panel.
There may be dirt or smears on the lens. Clean the lens as described in
Chapter 4.
The colors of the image are not right.
The color balance may be incorrect. If you’re displaying a computer
image, adjust the red, green, and blue settings in the Computer image
option menu. If you’re displaying video, adjust the color and tint
(NTSC only) settings on the Video image main menu.
There is no sound.
First check that the volume setting is not turned all the way down and
that the video/audio cable is securely attached to both the projector
and the audio source.
The wrong source is selected. Use the Source button on the remote
control or control panel to change the source.545 l Troubleshooting
