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.

Make sure the lamp has not been in use for over 2,050 hours. The lamp automatically shuts off at 2,050 hours and the LED blinks orange. See “Replacing the Projection Lamp” on page 33.

Check the projector’s lamp to ensure that it is securely con- nected in the lamp module. Make sure the lamp door is installed. See “Replacing the Projection Lamp” on page 33.

Problem: Only the start-up screen displays

Verify that the cables are connected correctly. See page 9 through page 12 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 Computer and Video (remote only)” on page 18.

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 44 or your computer’s manual for details.
