Problem: Image is too wide or narrow for screen
•
Adjust the zoom or projector placement.
•
Adjust the width of the image. See page 24.
Problem: Image is out of focus
•
Turn the projection lens to focus the image.
•
Make sure the projection screen is at least 3.6 feet (1 m) from
the projector, and that the projector is at a 90 degree angle to
the screen.
•
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 System menu. The image should immediately return to
forward projection. See page 25.
Problem: Projected image is distorted
•
Try resetting the projector. See page 23.
•
Adjust the tuning of the image. See page 24.
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, color and/or
contrast in the Main menu. See page 22.
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 31.
Problem: Lamp shuts off
•
A minor power surge may cause the lamp to shut off. Turn off
the projector, wait at least a minute, then turn it back in.
•
Make sure the vents on the bottom and back of the projector
are not blocked.
