Problem

No Video

Possible Solution

Check that all components in the system (monitor,

cameras, VCRs, multiplexers, etc.) have power and

are turned on.

Check that the camera lens cap is removed and the

lens is set to proper aperture.

Check cable(s) for proper connections and

condition.

Connect a known good video source directly to the

monitor to make certain the monitor is not the

problem.

If no video equipment is “looped through” the

monitor, make certain that a cable is NOT

connected to the loop-through connector.

Make certain the Under Scan LED is off.

Enter the Menu and adjust the Contrast, Brightness,

Color and Tint settings.

Check that the lens aperture is set correctly.

Enter the Menu and adjust the Brightness setting.

Enter the Menu and adjust the H-Position and V-

Positon as necessary.

Move the cursor to the bottom menu item using the

Up or Down buttons. Then, scroll through the

language choices using the Left and Right buttons.
