qA blank screen is displayed.
The computer signal cannot be interpreted by the 
projector. Verify the display format (see page 69, 70). 
When you see a blank screen, you cannot access the 
projector menus.
qThe 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 
operation panel. 
There may be dirt or smears on the lens. Clean the lens as 
described in Chapter 4, “Maintenance.”
qThe 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.
qThere is no sound.
First check that the volume setting is not turned all the way 
down and that the RCA audio cable is securely attached to 
both the projector and the audio source. Also, make sure 
that the Mute button is off.
The wrong source is selected. Press either the Computer or 
Video button on the remote control or Source button on 
the operation panel to select the proper source.
