1. General Information

1-1 General Guidelines

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

possibility to get electrical shock from the live power supply or charged electrical parts (even 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

excessive moisture. This TV must not be exposed to dripping or splashing water, and objects

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

products industry at large to be environmentally responsible. Lead-free solder must be used in the

servicing and repair of this product.

1-2-5. Use the genewing parts (specified parts)

Special parts which have purposes of fire retardant (resistors),high-quality sound (capacitors), low

noise(resistors), etc. are used.
When replacing any of components, be sure to use only manufacture's specified parts shown in
the parts list.

Safety Component

● Components identified by mark have special characteristics important for safety.

3

1-2-6. Safety Check after Repairment

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

1-2-7. Ordering Spare Parts

Please include the following informations when you order parts. (Particularly the Version

letter)

1. Model number and Version letter
The model number can be found on the back of each product and the Version letter can
