• Protect the power cord from being walked on
or pinched particularly at plugs, convenience
receptacles, and the point where they exit
from the apparatus.
• CAUTION concerning the Power Cord
(Can differ by country):
It is recommended that appliances be
placed upon a dedicated circuit; that is, a
single outlet circuit which powers only that
appliance and has no additional outlets or
branch circuits. Check the specification
page of this owner’s manual to determine
necessary power requirements for this set.
Do not connect too many appliances to the
same AC power outlet as this could result
in fire or electric shock. Do not overload
wall outlets. Overloaded wall outlets,
loose or damaged wall outlets, extension
cords, frayed power cords, or damaged or
cracked wire insulation are dangerous. Any
of these conditions could result in electric
shock or fire. Periodically examine the cord
of your appliance, and if its appearance
indicates damage or deterioration, unplug
it, discontinue use of the appliance, and
have the cord replaced with an exact
• Only use attachments/accessories specified
by the manufacturer.

• Grounding
• Cleaning
(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, lightening rods, or gas pipes.
When cleaning, unplug the power cord and
wipe gently with a soft cloth to prevent
scratching. Do not spray water or other
liquids directly on the TV as electric shock
may occur. Do not clean with chemicals such
as alcohol, thinners, or benzine.
• Moving
Make sure the product is turned off,
unplugged, 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
Short-circuit
Breaker
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, any objects to
fall into the product, and do not drop anything
onto the screen.
• 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 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 so as 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
an antenna discharge unit, size of grounding
conductors, location of antenna discharge
unit, connection to grounding electrodes and
requirements for the grounding electrode.

• Dot Defect
Preventing image burn or burn-in on your
TV screen
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
• If a fixed image displays on the TV screen for
a long period of time, it will be imprinted and
become a permanent disfigurement on the
screen. This is image burn or burn-in and not
covered by the warranty.
• If the aspect ratio of the TV is set to 4:3 for a
long period of time, image burn may occur on
the letterboxed area of the screen.
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 high-speed 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.
• Avoid displaying a fixed image on the TV
screen for a long period of time to prevent
image burn.
• 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.
• 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.
• 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.

17. Extended 3D (Command: x v) (For 3D TV)
Digital channels have a Physical, Major, and
Minor channel number. The Physical number is
the actual digital channel number, the Major is
the number that the channel should be mapped
to, and the Minor is the sub-channel. Since the
ATSC tuner automatically maps the channel to
the Major number, the Physical number is not
required when sending a command.

The table above lists the binary code which
must be converted to Hexadecimal before
sending. For example:
When TV is in the standby mode, TV will turn
on by POWER button of remote control only.
The binary code to tune the sub source to
an NTSC cable channel is 1000 0001, which
translates to 81 in Hex.

Example) To specify the value of the 5th band
(10 kHz) as +5:
Data 05 = 0010 0010 in binary = 22
Total = ma 00 00 00 1E 00 03 22
To specify the value of the 5th band as +5,
100 in binary, which falls in 7th, 6th and
5th bit, is necessary. To calculate the value,
take 0, with the minimum value of -10, as a
base. Then the value for +5 is 15 that equals
01111 in binary. To consolidate these values
and send it as a command, first, put the two
binary digits together: 10001111. This equals
8F in hexadecimal. Enter jv 00 8F to use as a
command.

CHILD SAFETY:
PROPER TELEVISION PLACEMENT MATTERS
THE CONSUMER ELECTRONICS INDUSTRY CARES
• Manufacturers, retailers and the rest of the consumer electronics industry are committed to
making home entertainment safe and enjoyable.
• As you enjoy your television, please note that all televisions – new and old- must be supported on
proper stands or installed according to the manufacturer’s recommendations. Televisions that
are inappropriately situated on dressers, bookcases, shelves, desks, speakers, chests, carts, etc.,
may fall over, resulting in injury.
TUNE IN TO SAFETY
• ALWAYS follow the manufacturer’s recommendations for the safe installation of your television.
• ALWAYS read and follow all instructions for proper use of your television.
• NEVER allow children to climb on or play on the television or the furniture on which the television
is placed.
• NEVER place the television on furniture that can easily be used as steps, such as a chest of
drawers.
• ALWAYS install the television where it cannot be pushed, pulled over or knocked down.
• ALWAYS route cords and cables connected to the television so that they cannot be tripped
over, pulled or grabbed.
WALL OR CEILING MOUNTYOUR TELEVISION
• ALWAYS contact your retailer about professional installation if you have any doubts about your
ability to safely mount your television.
• ALWAYS use a mount that has been recommended by the television manufacturer and has a
safety certification by an independent laboratory (such as UL, CSA, ETL).
• ALWAYS follow all instructions supplied by the television and mount manufacturers.
• ALWAYS make sure that the wall or ceiling where you are mounting the television is appropriate.
Some mounts are not designed to be mounted to walls and ceilings with steel studs or cinder
block construction. If you are unsure, contact a professional installer.
• Televisions can be heavy. A minimum of two people is required for a wall or ceiling mount
installation.
MOVING AN OLDER TELEVISION TO A NEW PLACE IN
YOUR HOME
• Many new television buyers move their older CRT televisions into a secondary room after the
purchase of a flat-panel television. Special care should be made in the placement of older CRT
televisions.
• ALWAYS place your older CRT television on furniture that is sturdy and appropriate for its size
and weight.
• NEVER place your older CRT television on a dresser where children may be tempted to use the
drawers to climb.
• ALWAYS make sure your older CRT television does not hang over the edge of your furniture.
