•Make sure that the power cord is properly connected to a fully functional 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 35.
•Make sure that the cables do not have any bent pins.
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 25 for more infor- mation.
Problem: The screen resolution is not right
•Make sure the computer’s video card is set for a resolution of no greater than 1024x768.
