1. Precautions

1-1. Safety Precautions

Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as electrical shock.

1-1-1. Warnings

For continued safety, do not attempt to modify the circuit board.

WARNING

1-1-2. Servicing the LED TV

When servicing the LED TV, Disconnect the AC line cord from the AC outlet.1.

It is essential that service technicians have an accurate voltage meter available at all times. Check the calibration of this 2. meter periodically.

1-1-3. Fire and Shock Hazard

Before returning the monitor to the user, perform the following safety checks:

Inspect each lead dress to make certain that the leads are not pinched or that hardware is not lodged between the 1. chassis and other metal parts in the monitor.

Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and 2. compartment covers or shields, isolation resistorcapacitor networks, mechanical insulators, etc.

Leakage Current Hot Check:3.

Disconnect the AC power and DC power jack before servicing.

1-1-4. Product Safety Notices

Some electrical and mechanical parts have special safetyrelated characteristics which are often not evident from visual inspection. The protection they give may not be obtained by replacing them with components rated for higher voltage,

wattage, etc. Parts that have special safety characteristics are identied by

replacement that does not have the same safety characteristics as the recommended replacement part might create

shock, re and/or other hazards. Product safety is under review continuously and new instructions are issued whenever

appropriate.

1. Precautions

1-2. Servicing Precautions

An electrolytic capacitor installed with the wrong polarity might explode.

WARNING

Before servicing units covered by this service manual, read and follow the Safety Precautions section of

CAUTION

NOTE

1-2-1. General Servicing Precautions

Always unplug the unit’s AC power cord from the AC power source and disconnect the DC Power Jack before 1. attempting to: (a) remove or reinstall any component or assembly, (b) disconnect PCB plugs or connectors, (c) connect a test component in parallel with an electrolytic capacitor.

Some components are raised above the printed circuit board for safety. An insulation tube or tape is sometimes used. 2. The internal wiring is sometimes clamped to prevent contact with thermally hot components. Reinstall all such elements to their original position.

After servicing, always check that the screws, components and wiring have been correctly reinstalled. Make sure that 3. the area around the serviced part has not been damaged.

Check the insulation between the blades of the AC plug and accessible conductive parts (examples: metal panels, input 4. terminals and earphone jacks).

Insulation Checking Procedure: Disconnect the power cord from the AC source and turn the power switch ON. Connect 5. an insulation resistance meter (500 V) to theblades of the AC plug. The insulation resistance between each blade of the AC plug and accessible conductive parts (see above) should be greater than 1 megohm.

Always connect a test instrument’s ground lead to the instrument chassis ground before connecting the positive lead; 6. always remove the instrument’s ground lead last.

If unforeseen circumstances create conict between the following servicing precautions and any of the

safety precautions, always follow the safety precautions.

1. Precautions

1-3. Static Electricity Precautions

Some semiconductor (solid state) devices can be easily damaged by static electricity. Such components are commonly

called Electrostatically Sensitive Devices (ESD). Examples of typical ESD are integrated circuits and some eld-effect

transistors. The following techniques will reduce the incidence of component damage caused by static electricity.

Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your 1. body by touching a known earth ground. Alternatively, wear a discharging wrist-strap device. To avoid a shock hazard, be sure to remove the wrist strap before applying power to the monitor.

After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to prevent 2. accumulation of an electrostatic charge.

Do not use freon-propelled chemicals. These can generate electrical charges sufcient to damage ESDs.3.

Use only a grounded-tip soldering iron to solder or desolder ESDs.4.

Use only an anti-static solder removal device. Some solder removal devices not classied as “anti-static” can generate 5. electrical charges sufcient to damage ESDs.

Do not remove a replacement ESD from its protective package until you are ready to install it. Most replacement ESDs 6. are packaged with leads that are electrically shorted together by conductive foam, aluminum foil or other conductive materials.

Immediately before removing the protective material from the leads of a replacement ESD, touch the protective material 7. to the chassis or circuit assembly into which the device will be installed.

Be sure no power is applied to the chassis or circuit and observe all other safety precautions.

CAUTION

Minimize body motions when handling unpackaged replacement ESDs. Motions such as brushing clothes together, or 8.

lifting your foot from a carpeted oor can generate enough static electricity to damage an ESD.

1. Precautions

1-4. Installation Precautions

For safety reasons, more than a people are required for carrying the product.1.

Keep the power cord away from any heat emitting devices, as a melted covering may cause re or electric shock.2.

Do not place the product in areas with poor ventilation such as a bookshelf or closet. The increased internal temperature 3.

may cause re.

Bend the external antenna cable when connecting it to the product. This is a measure to protect it from being exposed 4.

to moisture. Otherwise, it may cause a re or electric shock.

Make sure to turn the power off and unplug the power cord from the outlet before repositioning the product. Also check 5.

the antenna cable or the external connectors if they are fully unplugged. Damage to the cord may cause re or electric

shock.

Keep the antenna far away from any high-voltage cables and install it rmly. Contact with the highvoltage cable or the 6. antenna falling over may cause re or electric shock.

When installing the product, leave enough space (0.4m) between the product and the wall for ventilation purposes. 7.

A rise in temperature within the product may cause re.

If an equipment is provided with a replaceable battery, and if replacement by an incorrect type could result in an 8. explosion (for example, with some lithium batteries), the following applies:

Risk of explosion if battery is replaced by an incorrect type dispose of used batteries according to • the instructions.

Do not dispose of batteries in a re.•

Do not short circuit, disassemble or overheat the batteries.•

CAUTION

Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent • type.

Do not be exposed to excessive heat such as sunshine, re or the like.•

The Smart Touch Control makes it easier and more convenient to use the TV. For example, you can use the remote control's built-in touchpad to move the focus and make selections as you would on a computer using a mouse. In addition, you can use the virtual control panel displayed on the screen to change channels, play media les, and access favorites.

Connecting to the TV 

In order to operate the TV using a Smart Touch Control unit, you must rst pair it to the TV via Bluetooth.

To turn on the TV, point the Smart Touch Control at the remote control receiver of the TV and press the TV button. The 1. remote control receiver's location may vary depending on the model.

A Bluetooth icon will appear at the bottom left of the screen as shown below. The TV will then attempt to connect to the 2. Smart Touch Control unit automatically

Reconnecting the Smart Touch Control Unit 

If you need to reestablish the connection between the TV and the Smart Touch Control unit, press the pairing button at the back of the Smart Touch Control unit.

The pairing button can be accessed by removing the control unit's battery cover. Pressing the pairing button automatically reestablishes the connection between the control unit and the TV.
