When mounting a TV on the wall, make sure not to install the TV by the hanging power and signal cables on the back of the TV.
Do not allow an impact shock or any objects to fall into the product, and do not drop onto the screen with something.
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.

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.

FEATURE OF THIS TV

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
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.

In addition to adhering to the new Energy Star 3.0 specification, LG HDTVs have energy-saving options like the ability to choose a content-specific setting, "video mute" or engaging exclusive Intelligent Sensor technology.
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.
Stream movies, TV shows and video, and get up to the minute news, stock information and weather updates directly to your TV using Yahoo!, Netflix and YouTube.
View videos and photos and listen to music on your TV through USB 2.0 (‘videos’ dependent on model).
Some of these features are not available on all models.

SECURING THE TV TO THE WALL TO PREVENT FALLING WHEN THE TV IS USED ON A STAND

We recommend that you set up the TV close to a wall so it cannot fall over if pushed backwards. Additionally, we recommend that the TV be attached to a wall so it cannot be pulled in a forward direction,
potentially causing injury or damaging the product. Caution: Please make sure that children don’t climb on or hang from the TV.
Insert the eye-bolts (or TV brackets and bolts) to tighten the product to the wall as shown in the picture.
*If your product has the bolts in the eye-bolts position before inserting the eye-bolts, loosen the bolts. * Insert the eye-bolts or TV brackets/bolts and tighten them securely in the upper holes.
Secure the wall brackets with the bolts (sold separately) to the wall. Match the height of the bracket that is mounted on the wall to the holes in the product.
Ensure the eye-bolts or brackets are tightened securely.
Use a sturdy rope (sold separately) to tie the product. It is safer to tie the rope so it becomes horizontal between the wall and the product.
You should purchase necessary components to prevent the TV from tipping over (when not using a wall mount).
Image shown may differ from your TV.
GG
Use a platform or cabinet strong enough and large enough to support the size and weight of the TV.
GG
To use the TV safely make sure that the height of the bracket on the wall and the one on the TV are the same.
