Measures (Remedy)
Move the device away from the monitor.
Set the [DEGAUSS] item in the <MAIN MENU>
screen to degauss the screen.
When degaussing, wait more than 30 minutes for
maximum effect.
Adjust the picture size (H SIZE, V SIZE) or
position (H POSITION, V POSITION) in the
[SIZE/POSITION ADJ.] item in the <MAIN
MENU> screen.
Adjust the picture distortion (PINCUSHION, PIN.
BALANCE, TRAPEZOID and PARALLELO-
GRAM) in the [DISTORTION ADJ.] item in the
<MAIN MENU> screen.
It may not be possible to expand the picture due
to the selected input mode. In this case,
adjustment is impossible.
Adjust the [SCAN SIZE] or [ASPECT] item in
[FUNCTION SELECT] in the <MAIN MENU>
screen.
Set the CONTROL LOCK function to OFF.

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 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.
If the INPUT A or INPUT B indicator blinks:
It means that a malfunction has been detected by the monitor’s self-test function.
INPUT A indicator blinks : bus control malfunction
INPUT B indicator blinks : deflection control malfunction
When one of these indicators blink, the protection function automatically cuts power.
If this happens, turn the power off, unplug the monitor and consult a JVC-authorized dealer or service center for repair.
