1 Safety Precautions 

1.1. General Guidelines 

1. 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. 

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

installed. 

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

1.1.1. Leakage Current Cold Check 

1. Unplug the AC cord and connect a jumper between the two prongs on the plug. 

2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on 

the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to the 

chassis, the reading should be between 1M and 5.2M. 

When the exposed metal does not have a return path to the chassis, the reading must be 

1.1.2. Leakage Current Hot Check 

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

2. Connect a 1.5k, 10 watts resistor, in parallel with a 0.15F capacitors, 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 an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across the resistor. 

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

5. Reverse the AC plug in the AC outlet and repeat each of the above measurements. 

6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 or equivalent) 

may be used to make the hot checks, leakage current must not exceed 1/2 milliamp. In case a measurement is outside 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.

1.4. Before Repair and Adjustment 

Disconnect AC power to discharge unit AC Capacitors as such (C5700,C5701, C5703, C5704, C5705, C5708) through a 10 , 10 

W resistor to ground. 

Caution: 

DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. 

After repairs are completed, restore power gradually using a variac, to avoid overcurrent. 

Current consumption at AC 110~127 V, 60 Hz in Power ON, FM Tuner, No Signal, volume minimal mode should be ~ 400 mA. 

Current consumption at AC 220~240 V, 50 Hz in Power ON, FM Tuner, No Signal, volume minimal mode should be ~ 300 mA. 

1.5. Protection Circuitry 

The protection circuitry may have operated if either of the following conditions are noticed: 

• No sound is heard when the power is turned on. 

• Sound stops during a performance. 

The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are 

“shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used. 

If this occurs, follow the procedure outlines below: 

1. Turn off the power. 

2. Determine the cause of the problem and correct it. 

3. Turn on the power once again after one minute. 

Note: 

When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.

2 Warning 

2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatic 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. 

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. 

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 charge 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. (Most 

replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum 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).

2.3. Service caution based on Legal restrictions 

2.3.1. General description about Lead Free Solder (PbF) 

The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards used for this 

equipment in considering the globally environmental conservation. 

The normal solder is the alloy of tin (Sn) and lead (Pb). On the other hand, the lead free solder is the alloy mainly consists of tin 

(Sn), silver (Ag) and Copper (Cu), and the melting point of the lead free solder is higher approx.30 degrees C (86F) more than that 

of the normal solder. 

Definition of PCB Lead Free Solder being used 

The letter of “PbF” is printed either foil side or components side on the PCB using the lead free solder. 

(See right figure) 

Service caution for repair work using Lead Free Solder (PbF) 

• The lead free solder has to be used when repairing the equipment for which the lead free solder is used. 

(Definition: The letter of “PbF” is printed on the PCB using the lead free solder.) 

• To put lead free solder, it should be well molten and mixed with the original lead free solder. 

• Remove the remaining lead free solder on the PCB cleanly for soldering of the new IC. 

• Since the melting point of the lead free solder is higher than that of the normal lead solder, it takes the longer time to melt the 

lead free solder. 

• Use the soldering iron (more than 70W) equipped with the temperature control after setting the temperature at 350±30 degrees 

C (662±86F). 

Recommended Lead Free Solder (Service Parts Route.) 

• The following 3 types of lead free solder are available through the service parts route. 

RFKZ03D01K-----------(0.3mm 100g Reel) 



Note 

* Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%

2.4. Handling Precautions for Traverse Unit 

The laser diode in the optical pickup unit may break down due to static electricity of clothes or human body. Special care must be 

taken avoid caution to electrostatic breakdown when servicing and handling the laser diode in the traverse unit. 

2.4.1. Cautions to Be Taken in Handling the Optical Pickup Unit 

The laser diode in the optical pickup unit may be damaged due to electrostatic discharge generating from clothes or human body. 

Special care must be taken avoid caution to electrostatic discharge damage when servicing the laser diode. 

1. Do not give a considerable shock to the optical pickup unit as it has an extremely high-precise structure. 

2. To prevent the laser diode from the electrostatic discharge damage, the flexible cable of the optical pickup unit removed 

should be short-circuited with a short pin or a clip. 

3. The flexible cable may be cut off if an excessive force is applied to it. Use caution when handling the flexible cable. 

4. The antistatic FPC is connected to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexible 

cable, cut off the antistatic FPC.

2.4.2. Grounding for electrostatic breakdown prevention 

Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be damaged by static electricity 

in the working environment. Proceed servicing works under the working environment where grounding works is completed. 

2.4.2.1. Worktable grounding 

1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet. 

2.4.2.2. Human body grounding 

1. Use the anti-static wrist strap to discharge the static electricity form your body.
