Problems with the Image or Sound
131
◗ 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. If your projector is attached to a Macintosh, make
sure that the DIP switches on your Macintosh desktop adapter are set
correctly. (See your Macintosh documentation if you need
instructions.) When NO SIGNAL is displayed, you cannot access the
Video menu.
◗ A blank screen is displayed.
The computer signal cannot be interpreted by the projector. Verify the
display format (see page 137). When you see a blank screen, you
cannot access the projector menus.
◗ The image or parts of the image are blurred or not in focus.
Adjust the Brightness and Contrast settings on the Video menu. If
you’re viewing a computer image, also try adjusting the Tracking and
Sync buttons on the projector’s control panel.
There may be dirt or smears on the lens. Clean the lens as described on
page 118.
◗ The colors of the image are not right.
The color balance may be incorrect. If you’re displaying a computer
image, use the Color option in the Video menu to adjust the balance
of red, green, and blue. If you’re displaying video, adjust the Color and
Tint (NTSC only) settings on the Video menu.
