TROUBLESHOOTING
Before calling your dealer or service center for assistance, check the following:
1. Make sure the projector is connected to your computer or video equipment as described in the section "CONNECTING
PROJECTOR" on pages 11 ~ 13.
2. Check cable connections. Verify that all computer, video and power cords are properly connected.
3. Verify that all power is switched on.
4. If the projector still does not produce an image, re-start your computer.
5. If an image still does not appear, unplug the projector from your computer and check your computer monitor display. The
problem may be 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 power up the projector. Power the equipment back on in this order: Projector
then computer.)
