Solutions to Common Problems

Problem: Nothing on projection screen
Make sure that the power cord is properly connected to a func-
•
tional AC electrical outlet. Make sure that the power cord is
also properly connected to the projector.
If the projector is plugged into a power strip, make sure the
•
power strip is turned on.
Make sure you have removed the lens cap on the projection
•
lens at the front of the projector.
Make sure the projector is switched on.
•
Check the projector's lamp to ensure that it is securely con-
•
nected in the lamp module. See "Replacing the Projection
Lamp" on page 37.
Make sure that the cables do not have any bent pins. Check the
•
power cord for bent pins also.
Problem: Color or text not being projected
You might need to adjust the brightness up or down until the
•
text is visible. Refer to "Brightness" on page 27 for more infor-
mation.
Verify that the appropriate input source is selected. See "Com-
•
puter 1, 2 and 3" on page 23 or "Video 1 and 2" on page 24.
