TROUBLESHOOTING
Solutions to common problems related to your monitor are described here. If none of the solutions presented here solves the problem, unplug the monitor and consult a JVC-authorized dealer or service center for assistance. 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 t
he
structure of the cathode ray tube and will be deleted when another image is displayed.
●
Y
ou experience a mild electric shock when you touch the picture tube.
This phenomenon is due to a normal buildup of static
electricity on the CR
T
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 of
f on any monitor that is not being used.
