Placement for watching
We suggest you to watch the TV 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 TV 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 TV's
backlight setting is set to maximize the brightness of the TV.
However, uneven brightness may be observed when the LCD
TV is viewed in a dark environment without an input source or
a blank screen. This is a normal condition, not a malfunction
of the TV. 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 TV. The image may be uneven or the LCD panel may be
damaged.
• If the TV 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 TV 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 TV.
Doing so may break the screen glass and cause
serious injury.
If the surface of the TV cracks, unplug the AC
power cord before touching the TV. 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 TV yourself,
since opening the cabinet may expose you
to dangerous voltage or other hazards.
Ask qualified service personnel to do the
servicing for your TV.
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 TV, ask the service technician to
perform routine safety checks (as specified by the manufacturer) to
determine that the TV is safe for operating, and to so certify.
Ask a qualified service technician to dispose of the TV.
