Problem: Image and menus are reversed left to right

•Rear projection mode is probably turned on. Turn Rear Projec- tion off in the Controls menu. The image should immediately return to forward projection. See “Rear Projection” on

page 28.

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

•Adjust the brightness. See “Brightness” on page 21.

•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

Try these steps in this order.

1Deactivate the screen saver on your computer.

2Turn Auto Image off and then back on again. See “Auto Image” on page 24.

3Turn Auto Image off and adjust the synchronization and track- ing manually to find an optimal setting. See “Manual Sync” on page 25 and “Manual Tracking” on page 25.

•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

•Just as there are differences in the displays of different moni- tors, there are often differences between the computer image and the projected image. Adjust the brightness, tint and/or contrast from the Display menu. See “Brightness” on page 21, “Tint” on page 21 and “Contrast” on page 21.

Problem: Lamp seems to be getting dimmer

•The lamp begins to lose brightness when it has been in use for a long time. Replace the lamp as described in “Replacing the Projection Lamp” on page 33.
