1-2. General GuidelinesWhen 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 Check2) Leakage Current Hot Check3) Prevention of Electro Static Discharge (ESD) to Electrostatically Sensitive
1-3. Important Notice1-3-1. Follow the regulations and warningsMost 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.
1-3-2. Be careful to the electrical shock������������� ���������� �������������������������������������������������������to rain or excessive moisture. This TV must not be exposed to dripping or splashing water, ���������������������������������������������������������������������������������
1-3-3. 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 techniques should be used to help reduce the incidence of component damage caused by electros static discharge (ESD).
1-3-4. About lead free solder (PbF)This product is manufactured using lead-free solder as a part of a movement within the consumer products industry at large to be environmentally responsible. Lead-free solder must be used in the servicing and repairing of this product.
�!"!#��$������ ������ ������%������������'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.

Check the insulation between the antenna terminal or external metal and the AC cord plug blades. And be sure the safety of that.
General Servicing Precautions1. Always unplug the receiver AC power cord from the AC power source before; a. Removing or reinstalling any component, circuit board module or any other receiver assembly. b. Disconnecting or reconnecting any receiver electrical plug or other electrical connection. c. Connecting a test substitute in parallel with an electrolytic capacitor in the receiver.
CAUTION: A wrong part substitution or incorrect polarity installation of electrolytic capacitors may result in an explosion hazard.
2. Test high voltage only by measuring it with an appropriate high voltage meter or other voltage measuring device (DVM, FETVOM, etc) equipped with a suitable high voltage probe. Do not test high voltage by "drawing an arc".
5. Do not defeat any plug/socket B+ voltage interlocks with which receivers covered by this service manual might be equipped.
?��$�����������������������:��������������������������������������������
CAUTION: @������������������������ ��������������:��������������������eiver.
3. Do not spray chemicals on or near this receiver or any of its assemblies.
4. Unless specified otherwise in this service manual, clean electrical contacts only by applying the following mixture to the contacts with a pipe cleaner, cotton-tipped stick or comparable non-abrasive applicator; 10% (by volume) Acetone and 90% (by volume) isopropyl alcohol (90%-99% strength).
CAUTION:�����������K�������������������$��������������������������������������������������������������������������������� Capacitors may result in an explosion hazard.
6. Do not apply AC power to this instrument and/or any of its electrical assemblies unless all solid-state device heat sinks are correctly installed.
7. Always connect the test receiver ground lead to the receiver chassis ground before connecting the test receiver positive lead.
Always remove the test receiver ground lead last. Capacitors may result in an explosion hazard.
9. Remove the antenna terminal on TV and turn on the TV.
10. Insulation resistance between the cord plug terminals and the eternal exposure metal should be more than Mohm by using the 500V insulation resistance meter.
11. 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

Electrostatically Sensitive (ES) Devices
1-3-7. Ordering Spare Parts
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed to prevent potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.
#���@��������������!������������������������������ ��������������������� ������������to damage ES devices.
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed.
CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
Some semiconductor (solid-state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor "chip" components. The following techniques should be used to help reduce the ncidence of component damage caused by static by static electricity.
4. Use only an anti-static type solder removal device. Some solder removal devices not ������������Y���!����Y����� ��������������������� ����������������� ��[\��������
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it.(Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material).
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the ����� ����:����������������������K�������� ��������������������:��������������� ��an ES device.)
Please include the following informations when you order parts. (Particularly the Version letter)
