The following are not malfunctions:

You may see two horizontal lines on the monitor. They are the shadows of the “damper lines” that are necessary for composing the monitor. These lines are not a malfunction.

INPUT SELECT

When a bright still image (such as a white cloth) is displayed for a long period, it may appear to be coloured. 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 operated next to 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.

When black vertical lines appear on the screen

Black vertical lines may appear on the screen if the aperture grill is tilted as a result of being shaken or jolted during shipment.

In this case, try tapping the monitor on the side. If this does get rid of the lines, follow the procedure below.

1.Display a white screen, so that the problem area can be seen clearly.

2.Maximize contrast and brightness, then place a bright white rectangle on the area.

3.After a while, the lines should disappear.
