TROUBLESHOOTING

NO IMAGE ON MAIN DISPLAY

If there is no image on the main screen, a signal will appear on the screen that states, “No Input, Check Cable”. If the cable from the computer to the display is secure, determine the color of the standby LED and follow the appropriate procedure below.

BLACK

Cause: If the standby LED is black, there is no power to the unit.

Recovery:

•Ensure the power cable is plugged into the source.

•Connect the power cable to the AC outlet. Ensure the AC outlet is active.

•Wake up the display by pressing the standby button.

ORANGE

Cause: If the standby LED is orange, there is no video signal.

Recovery:

•Ensure there is a video signal coming from the computer.

•If no image appears, press the Z button on the control panel.

•If this fails to activate the image, use the on-screen menu. Within the Configuration menu is the “Channel Select” option. Switch between A and B to activate the proper channel.

GREEN

Cause: When the standby LED is green, there is both power and a video signal. If there is no image on the main display, there is a possible hardware failure.

Recovery:

•Ensure the video signal coming from the computer is not a black screen.

•Contact Z Microsystems’ Customer Support Department.
