Error/Warning Displays
If for any reason an error occurs in this monitor, the LEDs above the picture adjusting knob flash at 1-second
intervals (informing you of the error/warning display).
Maintenance
• To clean the cabinet or surface of the liquid crystal protection panel, gently wipe with a soft, dry cloth.
If the surfaces are extremely dirty, use a soft cloth dipped in a weak detergent solution and then wrung-out to clean the
surfaces, then use a dry cloth to finish. Water or similar substances getting inside the monitor can cause a malfunction.
• Never use thinner or benzene to clean this unit.
Doing so would cause the surface of the monitor to become discolored, and cause paint to peel.
• Do not spray cleansers directly onto the monitor.
Water or similar substances getting inside the monitor can cause a malfunction.
Maintenance Inspections
Maintenance inspections are necessary for the user to use this equipment safely. It is important to keep monitor
functions in good condition at all times through periodical and appropriate maintenance. In order to use this monitor
for a long time, and to make full use of all of its functions, be sure to carry out the following maintenance
inspections.
1. Necessity of periodical maintenance services
A backlight is used in the liquid crystal panel. This
part (consumable) deteriorates as time passes, and
can cause performance levels to drop, or may cause
a malfunction.
Therefore, in addition to the after-service repairs
performed if a malfunction occurs, it is essential that
general servicing and maintenance servicing are
conducted on a regular basis, to prevent malfunctions
and accidents caused by the deterioration of
consumable parts, and to keep the monitor working
normally.
2. Standard maintenance time guidelines and items
to be performed
The following maintenance performance times give
standard guidelines for when to perform maintenance,
and do not indicate the individual lifespan of your
equipment. Also, note that the deterioration time
varies depending on the usage environment and way
in which the equipment is used.
* You cannot replace just the backlight unit on its own.
Error/Warning displays Symptom Solution
Inverter error
If a malfunction occurs in the inverter that
controls the backlight brightness, the
backlight will switch OFF.
The screen becomes completely black. Switch the power supply OFF once, then
switch it back ON again. If an error is still
displayed, contact the vendor where you
purchased the monitor.
Fan stop
Error
The fan in the back of the monitor stops if
a malfunction occurs. If a picture is being
displayed when the malfunction occurs, it
will continue being displayed as is. Switch the power supply OFF once, then
switch it back ON again. If the error is still
displayed after this, contact the vendor
where you purchased the monitor
immediately.
If a fan stop error occurs, setting “FAN
MOTOR” to “OFF” in the “SYSTEM
CONFIG” menu (refer to page 21) allows
you to continue using the monitor with
reduced screen brightness.
