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 INPUT SELECT A/B and DC INDICATOR lamps on the front panel start flashing after the screen
goes blank...
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/B
and DC INDICATOR 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.
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.
Points to be checked 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 UNDER SCAN button to remove 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 flashing.
2. Turn off the AC or DC switch on the rear panel.
3. When using the AC power supply, unplug the AC
power cord.
When using the DC power supply, remove the battery
or unplug the DC power cord.
4. Contact your dealer with the information about which
indicators are flashing.
