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 connected in
•
the lamp module. See "Replacing the Projection Lamp" on page 33.
Make sure that the cables do not have any bent pins.

You might need to adjust the brightness up or down until the text is
•
visible. Refer to "Brightness" on page 23 for more information.
Problem: The screen resolution is not right
Make sure the computer's video card is set for a resolution of no
•
