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 Points to be checked Measures (Remedy)
No power supply. Is the power plug loosened or disconnected? Firmly insert the power plug.
No picture with the
power on. Is the video signal output from the connected
component? Set the connected component correctly.
Is the input signal selected properly? Select the required video signal input with the
Input select button. (See page 6.)
Is the video cable disconnected? Connect the video signal cable fi rmly.
(See page 11.)
No sound. Is the audio signal output from the connected
component? Set the connected component correctly.
Is the volume output set to minimum? Adjust the speaker volume with the
VOLUME/SELECT buttons. (See page 6.)
Is the audio cable disconnected? Connect the audio signal cable fi rmly.
(See page 11.)
Shaking picture. Is the monitor close to a device generating a
strong magnetic fi eld? Move the device away from the monitor until the
picture stabilizes.
No colours, wrong
colour, or dark picture. Is the colour system selected properly? Set the COLOR SYSTEM in the <MENU>
screen mode to [AUTO] mode. (See page 7.)
Has the picture control setting (CONTRAST,
BRIGHT, CHROMA or PHASE) been changed? Set each picture control to the standard setting.
(See page 6.)
Unnatural, irregularly
coloured, or distorted
picture. Is the monitor close to a speaker, magnet or any
other device generating a strong magnetic fi eld? Move the device away from the monitor and turn
the monitor’s power off. Wait at least 30 minutes,
then turn the power on again.
Front panel button does
not function. Are the operation buttons on the front panel
locked? ( Has CONTROL LOCK function set to
ON?) Set the CONTROL LOCK to OFF in the
<SET-UP MENU> screen mode. (See pages 8
and 9.)
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 coloured. 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.
