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 and the green Power LED is lit.

•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 from the projection lens at the front of the projector.

•Make sure the projector is turned 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 39.

•Make sure that the CableWizard and 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 + or -” on page 22 for more information.

•Verify that the appropriate input source is selected. See “Com- puter” on page 22 or “Video” on page 23.

Problem: The screen resolution is not right

•Make sure the computer’s graphics card is set for a resolution of no greater than 1280x1024.

Problem: Image isn’t centered on the screen

•Reposition the image. Refer to “Horizontal position” on page 30 and “Vertical position” on page 30.

•If you’re using an extension cable between the CableWizard and the projector, make sure it’s InFocus-approved.
