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.
Problems
No power supply.
No picture with the
power on.
No sound.
Shaking picture.
No colors, wrong
color, or dark picture.
Unnatural, irregularly
colored, or distorted
picture.
Dark stripes appear
at the top and bottom
of the screen, picture
vertically squeezed.
The overall picture
size is too small.
Function buttons on
the front panel do not
function.
The INPUT SELECT
buttons do not
function.
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 be deleted when another image is displayed.
● You 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.
