What To Do If You See a Blank Screen

If an image doesn’t appear, try the following:

Make sure the cables are connected correctly, as described on page 11 for a projector or monitor or page 14 for a computer.

Make sure everything is turned on.

Make sure the Main and Upper lights on the control panel and the upper lamps are on.

If you are using a video source, such as a laptop or desktop computer, you may need to switch video sources. See the next section for instructions.

If an image still doesn’t appear, refer to Chapter 4 for more help.
