Troubleshooting
Before calling your dealer or service center for assistance, check the items below once again.
1. Make sure you have properly connected the projector to peripheral equipment as described on pages 22–24.
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.)
6. If a problem still persists, check the following solutions.
