CAUTION concerning the Power Cord:
It  is  recommend  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 be certain.
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  replacement  part  by  an  authorized
servicer.  Protect  the  power  cord  from  physical
or  mechanical  abuse,  such  as  being  twisted,
kinked,  pinched,  closed  in  a  door,  or  walked
upon.  Pay  particular  attention  to  plugs,  wall
outlets, and the point where the cord exits the
appliance. 
Do  not  make  the  TV  with  the  power  cord
plugged  in.  Do  not  use  a  damaged  or  loose
power  cord.  Be  sure  do  grasp  the  plug  when
unplugging the power cord. Do not pull on the
power cord to unplug the TV. WARNING - To reduce the risk of fire or electrical
shock,  do  not  expose  this  product  to  rain,

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 out-
let).  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.

If  an  outdoor  antenna  is  installed,  follow  the
precautions below. An outdoor antenna system
should  not  be  located  in  the  vicinity  of  over-
head  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 dis-
charge  unit,  connection  to  grounding  elec-
trodes  and  requirements  for  the  grounding
electrode.

“Cracking”  noise:  A  cracking  noise  that  occurs
when  watching  or  turning  off  the  TV  is  gener-
ated  by  plastic  thermal  contraction  due  to
temperature  and  humidity.  This  noise  is  com-
mon  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 on the product.This generat-
ed sound does not affect the performance and
reliability of the product.2023

FEATURE OF THIS TV
Manufactured  under  license  from  Dolby  Laboratories.
“Dolby“and  the  double-D  symbol  are  trademarks  of
Dolby Laboratories. 
When a fixed image (e.g. logos, screen menus, video game, and computer display) is displayed on the TV
for an extended period, it can become permanently imprinted on the screen. This phenomenon is known
as “image burn” or “burn-in.” Image burn is not covered under the manufacturer’s warranty. 
In order to prevent image burn, avoid displaying a fixed image on your TV screen for a prolonged period
(2 or more hours for LCD, 1 or more hours for Plasma). 
Image  burn  can  also  occur  on  the  letterboxed
areas  of  your  TV  if  you  use  the  4:3  aspect
ratio setting for an extended period.
IMPORTANT INFORMATION TO PREVENT “IMAGE BURN
/ BURN-IN” ON YOUR TV SCREEN

television, HDTV formats include 1080i and 720p
resolutions.

This  TV  contains  the  detailed  calibrations  necessary
for  professional  certification  by  the  Imaging  Science
Foundation. The resulting ISF “day” and “night” modes
will  then  be  accessible  by  the  user  to  experience  the
best their LG HDTV has to offer.
Sophisticated  and  detailed  calibrations  can  be  made
through the ISFccc mode.
Detailed calibration requires a licensed technician.
Please  contact  your  local  dealer  to  inquire  about  an
ISF certified technician.
AV Mode is three preset picture and audio settings. It
allows  the  viewer  to  quickly  switch  between  common
settings. It includes Cinema, Sports, and Game Modes.
Displays HDTV programs in full 1920 x 1080p resolu-
tion for a more detailed picture.
Automatically  enhances  and  amplifies  the  sound  of
human  voice  frequency  range  to  help  keep  dialogue
audible when background noise swells.
Unlike other sensors which can only sense brightness
of ambient light, LG’s “Intelligent Sensor” uses 4,096
sensing  steps  to  evaluate  its  surroundings.  Using  a
sophisticated  algorithm,  the  LG  processes  picture
quality  elements  including  brightness,  contrast,  color,
sharpness  and  white  balance.  The  result  is  a  picture
optimized  for  it’s  surroundings,  more  pleasing  to
watch  and  which  can  also  save  up  to  50%  in  power
consumption. 
View  videos  and  photos  and  listen  to  music  on  your
TV through USB 2.0 (‘videos’ dependent on model).
