• Grounding

(Except for devices which are not grounded.)
Ensure that you connect the earth ground
wire to prevent possible electric shock (i.e. a
TV with a three-prong grounded AC plug must
be connected to a three-prong grounded AC
outlet).
If grounding methods are not possible, have
a qualified electrician install a separate circuit
breaker. Do not try to ground the unit by
connecting it to telephone wires, lightning rods,
or gas pipes.

• As long as this unit is connected to the AC wall
outlet, it is not disconnected from the AC power
source even if the unit is turned off.

• Do not attempt to modify this product in any
way without written authorization from LG
Electronics. Unauthorized modification could
void the user’s authority to operate this product.

• Outdoor Antenna Grounding
(Can differ by country):
If an outdoor antenna is installed, follow the

ENGLISH

precautions below. An outdoor antenna system
should not be located in the vicinity of overhead
power lines or other electric light or power
circuits, or where it can come in contact with
such power lines or circuits as death or serious
injury can occur. Be sure the antenna system is
grounded to provide some protection against
voltage surges and built-up static charges.
Section 810 of the National Electrical Code (NEC)
in the U.S.A. provides information with respect
to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to

and all cables have been removed. It may take 2
or more people to carry larger TVs. Do not press
or put stress on the front panel of the TV.

• Ventilation

Install your TV where there is proper ventilation.
Do not install in a confined space such as a
bookcase. Do not cover the product with cloth or
other materials while plugged. Do not install in
excessively dusty places.

• If you smell smoke or other odors coming from
the TV, unplug the power cord and contact an
authorized service center.

• Keep the product away from direct sunlight.

• Never touch this apparatus or antenna during a
lightning storm.

• When mounting a TV on the wall, make sure not
to install the TV by hanging the power and signal
cables on the back of the TV.

• Do not allow an impact shock or any objects to

• Dot Defect

The panel is a high technology product with
resolution of two million to six million pixels.
In a very few cases, you could see fine dots on
the screen while you’re viewing the TV. Those
dots are deactivated pixels and do not affect the
performance and reliability of the TV.

• Generated Sound
Cracking noise A cracking noise that occurs
when watching or turning off the TV is
generated by plastic thermal contraction due to
temperature and humidity. This noise is common
for products where thermal deformation is
required.

Electrical circuit humming/panel buzzing

A low level noise is generated from a high­speed switching circuit, which supplies a large
amount of current to operate a product. It varies
depending upon the product. This generated
sound does not affect the performance and
reliability of the product.

• Take care not to touch the ventilation openings.
When watching the TV for a long period, the
ventilation openings may become hot. This does
not affect the performance of the product or
cause defects in the product.

• Do not install this product on a wall if it could be
exposed to oil or oil mist. This may damage the
product and cause it to fall.

• If the TV feels cold to the touch, there may
be a small flicker when it is turned on. This is
normal; there is nothing wrong with TV. Some
minute dot defects may be visible on the screen,
appearing as tiny red, green, or blue spots.
However, they have no adverse effect on the TV’s
performance. Avoid touching the LCD screen or
holding your finger(s) against it for long periods
of time. Doing so may produce some temporary
distortion effects on the screen.
