Troubleshooting
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 29.
•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 18 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. A resolution of 800x600 yields the highest quality image.
Problem: Image isn’t centered on the screen
•Reposition the image. Refer to “Horizontal position” on page 22 and “Vertical position” on page 22.
•Be sure the projector is at a 90 degree angle to the screen.
Problem: Only the start-up screen displays
•Verify that the cables are connected correctly. See page 7 through page 9 for connection procedures.
•Verify that the proper input source is connected. See “Source” on page 15.
