Measures (Remedy)
Firmly insert the power plug.
Turn the main power ON. (See page 6.)
Set the connected component correctly.
Select the required video signal input with the
Input select button. (See page 10.)
Connect the video signal cable firmly.
(See pages 16 and 17.)
Set the connected component correctly.
Adjust the speaker volume with the VOLUME/
SELECT button. (See page 10.)
Connect the audio signal cable firmly.
(See pags 16 and 17.)
Move the device away from the monitor until the
picture stabilizes.
Set COLOR SYSTEM in the  screen to
AUTO. (See page 12.)
Set each picture control to the standard setting.
(See page 10.)
Press the COLOR OFF button and BLUE CHECK
button to adjust. (See page 11.)
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.
Switch the aspect ratio to 4:3 with the ASPECT
button on the front panel.
Press the UNDER SCAN button to turn off the
button. (See page 4.)
Set CONTROL LOCK in the 
screen to OFF. (See pages 13 and 14.)

(See page 18.)
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 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.

●To use the SWITCHED OUT terminal, the main power must be ON. (Unlike a bridged output, this connector outputs relocked
digital signals.)
●Signal output from the SWITCHED OUT terminal can be changed by selecting INPUT C (SDI 1) or INPUT D (SDI 2). You can
use the front panel buttons or do it via external control.
●When INPUT-A or INPUT-B is selected, this terminal outputs the signals last selected. In the standby mode, signals from the
SDI 1 connector are output.
