TROUBLESHOOTING

Before calling your dealer or service center for assistance, check the items below once again.

1.Make sure you have connected the projector to your computer or video equipment as described in “CONNECTING PROJECTOR” on pages 12–14.

2.Check the cable connection. Make sure that all computers, video equipment, and power cords are properly connected.

3.Make sure that all power is switched on.

4.If the projector still does not produce an image, restart your computer.

5.If an image still does not appear, disconnect the projector from your computer and check your computer monitor’s display. A problem may be noticed with your graphics controller rather than with the projector. (When you reconnect the projector, be sure to turn the computer and monitor off before you turn on the projector. Turn on equipment in the order of the projector and computer.)
