M a i n t e n a n c e & T r o u b l e s h o o t i n g

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 29.

3Adjust the synchronization and tracking manually to find an optimal setting. See “Manual Sync” on page 29 and “Manual Tracking” on page 30.

•If you’re using an extension cable between the CablePro and the projector, make sure it’s Boxlight-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 + or -” on page 22, “Color” on page 26 and “Contrast” on page 25.

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 37.

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.

Problem: Remote not operating correctly

•You might need to replace the batteries. See “Replacing the Bat- teries in the Remote Control” on page 39.

•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 25 feet.
