Try these steps in this order.

Deactivate the screen saver on your computer.

Turn 

off and then back on again. See “Auto 

Adjust the synchronization and tracking manually to find an 
optimal setting. See “Manual Sync” on page 36 and “Manual 
Tracking” on page 36.

•

If you’re using an extension cable between the CableWizard 
and the projector, make sure it’s In Focus-approved.

•

The problem could be with your computer’s graphics board. 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 Display 
menu. Just as there are differences in the displays of different 
monitors, there are often differences between the computer 
image and the projected image. See “Brightness” on page 27, 
“Tint” on page 31 and “Contrast” on page 31. 

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 Pro-
jection Lamp” on page 41.

Problem: Lamp shuts off
•

A minor power surge may cause the lamp to shut off. Turn the 
projector off, wait at least 30 seconds, then turn it back on.

•

You might need to replace the batteries. See “Replacing the Bat-
teries in the Remote Control” on page 43.

•

Make sure you’re pointing the remote either at the back or front 
of the projector, or at the projection screen.

•

Make sure the remote is within its operating range of 40 feet.
