and Sync buttons on the projector’s control panel or remote control.
There may be dirt or smears on the lens. Clean the lens as described
on page 110.

The colors of the image are not right.
The color balance may be incorrect. If you’re displaying a computer

of red, green, and blue. If you’re displaying video, adjust the Color
and Tint (NTSC only) settings on the Video menu.
Check your monitor’s color balance if you’re displaying a computer
image.
