The following are not malfunctions:
• About CRT tube reflection (when Zoom mode is used.)
The screen might appear as brownish white. This is due to a reflection of part of the image on the CRT caused by certain signal sources, and
it is not a malfunction.
• 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.

Self-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
blinking...
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 blink and the
monitor's power automatically turns off. If this happens, follow the steps below and contact your dealer to resolve the problem.
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 blink, 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 blinking,
you can use the monitor as usual.

Measures (Remedy)
Adjust the picture size (H. SIZE, V. SIZE) or
position (H. POSITION, V. POSITION) in "SIZE/
POSI. ADJ."
Adjust the picture distortion (PARALLELOGRAM,
TRAPEZOID) or tilt (ROTATION) in
"DISTORTION ADJ."
It may not be possible to expand the picture due
to the selected input mode. In this case,
adjustment is impossible.
Press the SCAN SIZE button to invalidate the
setting.
Change the input or the input signal.
Set the CONTROL LOCK function to "OFF."
Change the setting of the external control so that
the monitor can be operated by the buttons on
the front panel.
1.Check which indicators are blinking.
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 blinking.
