Problem: Image is “noisy” or streaked
Try these steps in this order.
1Deactivate the screen saver on your computer.
2Adjust the synchronization manually to find an optimal set- ting. See “Fine sync” on page 22.
•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 22, “Tint” on page 30 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 Projection Lamp” on page 36.
Problem: Lamp shuts off
•A minor power surge may cause the lamp to shut off. Unplug the projector, wait at least a minute, then plug it back in.
•Make sure the vents are not blocked.
