When servicing, observe the original lead dress. If a short circuit is found, replace all parts which

have been overheated or damaged by the short circuit.

After servicing, see to it that all the protective devices such as insulation barriers, insulation papers

shields are properly installed.

After servicing, make the following leakage current checks to prevent the customer from being

exposed to shock hazards.

1) Leakage Current Cold Check

2) Leakage Current Hot Check

3)Prevention of Electro Static Discharge(ESD)to Electrostatically Sensitive

1-2 Important notice

1-2-1. Follow the regulations and warnings

Most important thing is to list up the potential hazard or risk for the service personnel to open the

units and disassemble the units. For example, we need to describe properly how to avoid the

power is off).

This symbol indicates that high voltage is present inside. It is dangerous to

make any king of contact with any inside part of this product.

This symbol indicates that there are important operating and maintenance

instructions in the literture accompanying the appliance

1-2-2. Be careful to the electrical shock

To prevent damage which might result in electric shock or fire, do not expose this TV set to rain or

Filled with liquid, such as vases, must not be place on top of or above the TV

1-2-3. Electro static discharge (ESD)

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

Components commonly are called Electrostatically Sensitive (ES) Devices. The following

tech-niquesshouldbeusedtohelpreducetheincidenceofcomponentdamagecausedbyelectro

Static discharge (ESD).

1-2-4. About lead free solder (PbF)

This product is manufactured using lead-free solder as a part of a movement within the consum-er

Confirm that the screws ,parts and wiring which were removed in order to service are put in the

original positions, or whether there are the portions which are deteriorated around the serviced

places serviced or not. Check the insulation between the antenna terminal or external metal and

the AC cord plug blades. And be sure the safety of that.

Insuration Test

1. Unplug the plug from the AC outlet.

2. Remove the antenna terminal on TV and turn on the TV.

3. Insulation resistance between the cord plug terminals and the eternal exposure metal

should be more than M ohm by using the 500V insulation resistance meter

4. If the insulation resistance is less than M ohm, the inspection repair should be required.

If you have not the 500V insulation resistance meter, use a Tester.

External exposure metal: Antenna terminal Headphone jack
