The following are not malfunctions:

• When a bright still image (such as a white cloth) is displayed for a long period, it may appear to be colored. This is due to the structure of the cathode ray tube and will disappear when another image is displayed.

• You may sometimes experience a mild electric shock when you touch the picture tube. This phenomenon is due to a normal buildup of static electricity on the CRT and is not harmful.

• The monitor emits a strange sound when the room temperature changes suddenly. This is only a problem if an abnormality appears on the screen as well.

• If two or more monitors are placed close each other, their images may shake or be distorted. This phenomenon is due to mutual interference; it is not a malfunction. Move the monitors away from each other until the interference disappears or turn the power off on any monitor that is not being used.

7Self-check Indications

When the screen goes blank, and one or more of the INPUT SELECT A through D lamps on the front control

panel start flashing...

This monitor has a self-check function, which allows it to detect malfunctions and alert you. This makes troubleshooting easier. Whenever a problem occurs, a combination of “self-check indicators” (INPUT SELECT A through D lamps) will flash and the monitor’s power automatically turns off. If this happens, follow the steps below and contact your dealer to resolve the problem.

1. Check which indicators are flashing.

2. Turn off the main power switch on the back of the monitor.

3. Disconnect the Power Cord from the AC outlet.

4. Contact your dealer with the information about which indicators are flashing.

NOTE:

•If you turn on the monitor’s power immediately after turning it off (or after a short-term power failure), the self-check indicators may flash, and no image may be displayed.

When this happens, turn off the power, and wait at least 10 seconds before turning it on again. If the self-check indicators have stopped flashing, you can use the monitor as usual.
