Safety Precautions

General Guide Lines

1. 2. 3. 4.

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 touch current checks to prevent the customer from being exposed to shock hazards. Always ensure panel TKP0E16001 is correctly replaced before returning to customer (see Fig.1).
Fig. 1 Touch-Current Check

1. 2. 3. 4. 5. 6.

Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. Connect a measuring network for touch currents between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Fig. 2. Use Leakage Current Tester (Simpson 228 or equivalent) to measure the potential across the measuring network. Check each exposed metallic part, and measure the voltage at each point. Reserve the AC plug in the AC outlet and repeat each of the above measure. The potential at any point (TOUCH CURRENT) expressed as voltage U1 and U2, does not exceed the following values: For a. c.: U1 = 35 V (peak) and U2 = 0.35 V (peak); For d. c.: U1 = 1.0 V, Note: The limit value of U2 = 0.35 V (peak) for a. c. and U1 = 1.0 V for d. c. correspond to the values 0.7 mA (peak) a. c. and 2.0 mA d. c. The limit value U1 = 35 V (peak) for a. c. correspond to the value 70 mA (peak) a. c. for frequencies greater than 100 kHz. In case a measurement is out of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned to the customer.

Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensitive (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 incidence of component damage caused by electrostatic discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be removed for potential shock reasons prior to applying power to the unit under test. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge build up or exposure of the assembly. Use only a grounded-tip soldering iron to solder or unsolder ES devices. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static (ESD protected)" can generate electrical charge sufficient to damage ES devices. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices. 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). 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. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient to damage an ES device).

IMPORTANT SAFETY NOTICE
There are special components used in this equipment which are important for safety. These parts are marked by in schematic diagrams, exploded views and replacement parts list. It is essential that these critical parts should be replaced with manufacturers specified parts to prevent shock, fire, or other hazards. Do not modify the original design without permission of manufacturer.
About lead free solder (PbF)
Note: Lead is listed as (Pb) in the periodic table of elements. In the information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder. The Lead Free Solder used in our manufacturing process and discussed below is (Sn+Ag+Cu). That is Tin (Sn), Silver (Ag) and Copper (Cu) although other types are available. This model uses Pb Free solder in its manufacture due to environmental conservation issues. For service and repair work, wed suggest the use of Pb free solder as well, although Pb solder may be used. PCBs manufactured using lead free solder will have the PbF within a leaf Symbol stamped on the back of PCB. Caution Pb free solder has a higher melting point than standard solder. Typically the melting point is 50 ~ 70 F (30~40C) higher. Please use a high temperature soldering iron and set it to F (C). Pb free solder will tend to splash when heated too high (about 1100 F or 600 C). If you must use Pb solder, please completely remove all of the Pb free solder on the pins or solder area before applying Pb solder. If this is not practical, be sure to heat the Pb free solder until it melts, before applying Pb solder. After applying PbF solder to double layered boards, please check the component side for excess solder which may flow onto the opposite side. (see Fig.3)
Suggested Pb free solder There are several kinds of Pb free solder available for purchase. This product uses Sn+Ag+Cu (tin, silver, copper) solder. However, Sn+Cu (tin, copper), Sn+Zn+Bi (tin, zinc, bismuth) solder can also be used. (see Fig.4)

Schematic Diagrams

Components identified by mark have special characteristics important for safety. When replacing any of these components, use only manufacturers' specified parts. NOTE 1. RESISTOR All resistors are carbon W resistor, unless marked otherwise. Unit of resistance is OHM ( ) (k=1,000, M=1,000,000) CAPACITORS All capacitors are ceramic 50V unless marked otherwise. Unit of capacitance is F unless otherwise stated. COIL Unit of inductance is H, unless otherwise stated. TEST POINT Test Point Position

EARTH SYMBOL Chassis Earth (Cold) Line Earth (Hot)
VOLTAGE MEASUREMENT Voltage is measured by a D.C. voltmeter. Measurement conditions are as follows: Power source a.c. 220V-240V, 50Hz Colour Bar signal (RF) Receiving Signal All customer controls Maximum position
7. Indicates the Video signal path Indicates the Audio signal path
These schematic diagrams are the latest at time of printing and are subject to change without notice. REMARKS a. b. c. d. Do not touch the hot part, or the hot and cold parts at the same time, as you are liable to a shock hazard. Do not short circuit the hot and cold circuits as electrical components may be damaged. Do not connect an instrument, such as an oscilloscope, to the hot and cold circuits simultaneously as this may cause fuse failure. Connect the earth of the instruments to the earth connection of the circuit being measured. Make sure to disconnect the power plug before removing the chassis.
NOTE 1. The Power Supply Circuit contains a circuit area, which uses a separate power supply to isolate the earth connection. The circuit is defined by HOT and COLD indications in the schematic diagram. All circuits, except the Power Circuit, are COLD.
