Placement for watching
We suggest you to watch the LCD display at a distance of 3-7
times that of the screen height, and not in excessive brightness. It
is easy to cause eye fatigue if you watch LCD display for too long
or in a dark room. To obtain clear picture, do not expose the screen
to direct illumination or sunlight. Use spot lighting directed down
from the ceiling if you can.

LCD SCREEN

• Although the LCD screen is made with high precision technology
and has effective pixels of 99.99% or more, black dots or bright
points or light (red, blue, or green) may appear constantly on the
LCD screen. This is a structural property of the LCD panel and is
not a malfunction.
• The LCD screen is made with high-precision technology. To
achieve a high level of performance and picture quality, this LCD
display's backlight setting is set to maximize the brightness of
the LCD display. However, uneven brightness may be observed
when the LCD display is viewed in a dark environment without
an input source or a blank screen. This is a normal condition, not
a malfunction of the LCD display. To improve this condition,
change the Picture mode, Backlight setting, enable the Light
Sensor, or turn on the Power management.
• Avoid exposing the LCD screen surface to direct sunlight. It is
likely to damage the LCD panel.
• Do not push or scratch the LCD screen, or place objects on top
of the LCD display. The image may be uneven or the LCD panel
may be damaged.
• If the LCD display is used in a cold place, a smear may occur in
the picture or the picture may become dark. It is not caused by a
failure. This condition will improve as the temperature rises.
• When still pictures are displayed continuously, ghosting may
occur. It should disappear after a short period of time.
• The screen and cabinet get warm when the LCD display is in use.
This is a normal condition.
• Spraying insect repellent with volatile material on the screen will
cause damage.
• Do not make prolonged contact with rubber or plastic material.
Broken pieces
Do not throw anything at the LCD display.
Doing so may break the screen glass and cause
serious injury.
If the surface of the LCD display cracks, unplug
the AC power cord before touching the LCD
display. Otherwise electric shock may result.
Handling of broken glass and liquid crystal leakage
If the LCD panel gets damaged, crystalline liquid leakage may
occur, or scattered broken glass may result. Do not touch broken
glass or crystalline liquid which is toxic, with bare hands as cuts,
poisoning or skin irritation may occur. Also do not glass fragments
or leaked crystalline liquid get into your eyes or mouth. Should
either contacted your eyes or mouth, rinse the contacted area
thoroughly with water and consult your doctor.
SERVICING
Do not attempt to repair the LCD display
yourself, since opening the cabinet may
expose you to dangerous voltage or other
hazards. Ask qualified service personnel to
do the servicing for your LCD display.
Replacement parts
When replacement parts are required, be sure the service technician
certifies in writing that he/she has used replacement parts specified
by the manufacturer that have the same characteristics as the
original parts. Unauthorized substitutions may cause a fire, an
electric shock or other hazards.
Safety check
Upon completion of repairs to the LCD display, ask the service
technician to perform routine safety checks (as specified by
the manufacturer) to determine that the LCD display is safe for
operating, and to so certify.
Ask a qualified service technician to dispose of the LCD display.
