Troubleshooting

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

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.
