1. Make sure you have connected a projector to your computer or video equipment as described in the section "CONNECTING THE PROJECTOR"

2. Check cable connection. Verify that all computer, video and power cord are properly connected.

3. Verify that all power is switched on.

4. If a 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's 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. Turn the projector on, and then the computer.)

6. If the problem still exists, check the following chart.
