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.

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 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.

Cleaning 

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 benzene.

 

•

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 

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.

 

• If water or another substance enters the 

product (like an AC adapter, power cord, or TV), 

disconnect the power cord and contact the 

service center immediately. Otherwise, this may 

result in fire or electric shock.

 

• Use only an authorized AC adapter and power 

cord approved by LG Electronics.  

Otherwise, this may result in fire, electric shock, 

malfunction, or product deformation.

 

• Never disassemble the AC adapter or power 

cord. This may result in fire or electric shock.
