Troubleshooting
Problem: The projector is not running
•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 the projector is turned on.
Problem: Projector is running, but nothing appears on projec- tion screen
•Make sure you have removed the lens cap on the projection lens at the front of the projector.
•Check the projector’s lamp to ensure that it is securely con- nected in the lamp module. Make sure the lamp access grill is installed. See “Replacing the Projection Lamp” on page 27.
Problem: Only the start-up screen displays
•Verify that the cables are connected correctly. See page 7 for connection procedures.
•Make sure that the cables do not have any bent pins.
•Verify that the proper input source is connected. See “Source (keypad only) or Data and Video (remote only)” on page 14.
•You might need to turn everything off and power up the equipment again in the proper order. Refer to your com- puter’s documentation to determine the correct order.
•Make sure your laptop’s external video port is turned on. See the “Portable and Laptop Activation Chart” on page 38 or your computer’s manual for details.
•Make sure your computer’s video board is installed and con- figured correctly.
•Make sure your computer has a compatible video board. The projector isn’t CGA or EGA compatible.
