1 Safety Precautions

1.1. General Guidelines

1. When servicing, observe the original lead dress. If a short circuit is found, repla ce all parts which have been overheated or damaged by the short circuit.

2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.

3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.

1.2. Touch-Current Check

1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.

2. Connect a measuring network for touch cu rrents between each exposed metallic part on the set and a good earth ground such as a water pipe as shown in Figure 1.

3. Use the Leakage Current Tester (Simpson 228 or equivalent) to measure the potential across the measuring network.

4. Check each exposed metallic part and measure the voltage at each point.

5. The potential at any point (touch current) expressed as voltage U For AC: U1 = 35 V (peak) and U2 = 0.35 V (peak); For DC: U

NOTE :

The limit value of U DC.

The limit value U

= 1.0 V,

= 0.35 V (peak) for AC and U1 = 1.0 V for DC correspond to the values 0.7 mA (peak) AC and 2.0 mA

= 35 V (peak) for AC correspond to the value 70 mA (peak) AC for frequencies greater than 100 kHz.

and U2, do not exceed the following values:

6. Should a measurement be out of the limits specified, there is a possibility of a sh ock hazard, and the equipment should be repaired and rechecked before it is returned to the customer.

2 Prevention of Electro Static Discharge (ESD) to

Electrostatically Sensitive (ES) Devices

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such co mponents commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some fieldeffect transistors and semiconductor “chip” componen ts. The following techniques should be used to help reduce the incidence of component damage caused by electro static 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.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminium foil to prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static (ESD protected)” can generate electrical charges sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it (mo st replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminium foil or comparable conductive material).

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.

8. 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).

3 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 (PbF) used in our manufacturing process and discussed below is (Sn+Ag+Cu). Those are Tin (Sn), Silver (Ag) and Copper (Cu), although other types are available.

This model uses PbF in its manufacture due to environmental conservati on issues. For se rvice an d repair work, we woul d suggest the use of PbF as well, although Pb may be used.

PCBs manufactured using lead-free will have the “PbF with in a leaf Symbol” stamped on their back.

Caution

• PbF has a higher melting point than that of standard solder. Typically the melting point is 50 ~ 70°F (30~40°C) higher. Please use a high temperature soldering iron and set it to 700 ± 20°F (370 ± 10°C).

• PbF 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 PbF on the pins or solder area before applying Pb. If this is not practical, be sure to heat the PbF until it melts, before applying Pb.

• After applying PbF to double layered boards, please check the component side for excess solder which may flow onto the opposite side (see Figure 2).

Figure 2

Suggested PbF

There are several kinds of PbF available for purchase. This produ ct uses Sn+Ag+Cu (tin, silver, copper) solder. However, Sn+Cu (tin, copper) and Sn+Zn+Bi (tin, zinc, bismuth) solders can also be used.

11 Schematic Diagram

11.1. Schematic Diagram Notes

Notes :

1. Resistor Unit of resistance is OHM [Ω] (K = 1 000, M = 1 000 000).

2. Capacitor Unit of capacitance is μF unless otherwise noted.

3. Coil Unit of inductance is μF unless otherwise noted.

4. Test Point

: Test Point position

TX-LR32C10

5. Earth Symbol

: Chassis Earth (Cold) : Line Earth (Hot)

6. Vo ltage Measurement Voltage is measured using DC voltmeter . Conditions of the measurement are the following :

Power Source....................AC AUTO 110-240 V, 50/60 Hz

Receiving Signal................Colour Bar signal (RF)

All customer’s controls.......Maximum positions

7. Number in red circle indicates waveform number. (See waveform pattern table)

8. When an arrow mark ( ) is found, connection is easily found from the direction of the arrow.

9. Indicates the major signal flow: Video Audio

10. This schematic diagram is the latest at the time of printing and subject to change without notice.

Remarks :

1. The Power 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. Take the following precautions: All circuits, except the Power Circuit are cold. Precautions:

a. Do not touch the hot part or the hot and cold parts at the same time or you may be shocked. b. Do not short-circuit the hot and cold circuits or a fuse may blow and parts may break.

c. Do not connect an instrument such as an oscilloscope to the hot and cold circuits simultaneously or a fuse may blow.

Connect the earth of instruments to the earth connection of the circuit being measured.

d. Make sure to disconnect the power plug before removing the chassis.
