Problem: Image is out of focus

Turn the projection lens to focus the image.

Make sure the projection screen is at least 5 feet (1.5 m) from the projector.

Check the projection lens to see if it needs cleaning.

Problem: Image and menus are reversed left to right

Rear projection mode is probably turned on. Turn “Rear” off in the Custom Setup menu. The image should immediately return to forward projection. See “Image Mode” on page 21.

Problem: the projector displays vertical lines, “bleeding” or spots

Adjust the brightness. Refer to “Bright” on page 15 for more information.

Check the projection lens to see if it needs cleaning.

Problem: no sound

Adjust volume.

Verify audio/input connections.

Adjust audio source.

Problem: Image is “noisy” or streaked

Adjust the synchronization and tracking manually to find an optimal setting. See Sync and Tracking on page 18.

The problem could be with your computer’s video card. If possible, connect a different computer.

Problem: Projected colors don’t match the computer or video player’s colors

Adjust the brightness, tint and/or contrast from the menus. Just as there are differences in the displays of different moni- tors, there are often differences between the computer image and the projected image. Refer to “Bright” on page 15, or Tint or Contrast on page 18.
