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.
Points to be checked Measures (Remedy)
Move the device away from the monitor and turn
off the monitor. Wait at least 30 minutes, then turn
on the monitor.
Adjust "H. POSITION" or "V. POSITION" in SET-UP
MENU.
When the UNDER SCAN or ASPECT button is lit,
press the button to deactivate the function.
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.
