❑A blank screen is displayed.
The computer signal cannot be interpreted by the
projector. Verify the display format (see page 65 or 66).
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
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, “Maintenance.”
❑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 Video menu. If you’re displaying video, adjust the color
and tint (NTSC only) settings on the Video menu.
❑There is no sound.
First check that the volume setting is not turned all the way
down and that the audio/visual cable is securely attached to
both the projector and the audio source.
The wrong source is selected. Press either the Computer or
Video button on the remote control or control panel to
select the proper source.
