NOTE
 
► TV can be placed in standby mode in order to reduce the power consumptio\
n. And TV should be 
switched off using the power switch on the TV if it will not be watched for some time, as this will 
reduce energy consumption.
 
The energy consumed during use can be significantly reduced if the level\
 of 
brightness of the picture is reduced, and this will reduce the overall r\
unning cost.
 
 CAUTION
 
► Do not step on the glass stand or subject it to any impact. It may break\
, causing possible injury from frag-
ments of glass, or the TV may fall.
 
► Do not drag the TV. The floor or the product may be damaged.

When assembling the desk type stand, check 
whether the bolt is fully tightened. (If not tightened 
fully, the product can tilt forward after the product 
installation.) If you tighten the bolt with excessive 
force, the bolt can deviate from abrasion of the 
tightening part of the bolt. 
Carefully place the TV screen side down 
on a cushioned surface to protect the 
screen from damage.1
Assemble the parts of the  Stand Body with 
the  Stand Base of the TV.

KENSINGTON SECURITY 
SYSTEMCAREFUL INSTALLATION 
ADVICE 
 
■ You should purchase necessary components 
to fix the TV safety and secure to the wall on 
the market.
 
■    Position the TV close to the wall to avoid the 
possibility of it falling when pushed.
 
■    The instructions shown below are a safer way 
to set up the TV, by fixing it to the wall, avoid-
ing the possibility of it falling forwards if pulled. 
This will prevent the TV from falling forward 
and causing injury. This will also prevent the 
TV from damage. Ensure that children do not 
climb or hang from the TV.
3
Use the eye-bolts or TV brackets/bolts to fix the 
product to the wall as shown in the picture. 
(If your TV has bolts in the eyebolts, loosen then 
bolts.)
* Insert the eye-bolts or TV brackets/bolts and 
tighten them securely in the upper holes.
Secure the wall brackets with the bolts on the 
wall. Match the height of the bracket that is 
mounted on the wall.
Use a sturdy rope to tie the product for align-
ment. It is safer to tie the rope so it becomes 
horizontal between the wall and the product.

System.
For further information, contact http://www.kens-
ington.com, the internet homepage of the

NOTE
 
► When moving the TV undo the cords first.
 
► Use a platform or cabinet strong and large 
enough to support the size and weight of the TV.
 
► To use the TV safely make sure that the height of 
the bracket on the wall and on the TV is the 
same.
NOTE
 
► The Kensington Security System is an optional 
accessory.
 
► 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 monitors performance.
 
► Avoid touching the LCD screen or holding your 
finger(s) against it for long periods of time.
    Doing so may produce some temporary distortio
n
   effects on the screen.

► Should Install wall mount on a solid wall per-
pendicular to the floor.
 
► Should use a special wall mount, if you want 
to install it to ceiling or slanted wall.
 
► The surface that wall mount is to be mount-
ed on should be of sufficient strength to sup-
port the weight of TV set; e.g. concrete, nat-
ural rock, brick and hollow block.
 
► Installing screw type and length depends on 
the wall mount used. Further information, 
refer to the instructions included with the 
mount.
 
► LG is not liable for any accidents or damage 
to property or TV due to incorrect installa-
