1 Safety Precautions1.1. 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, ensure that all the protective devices such as insulation barriers, insulation papers shields are properly installed. 3. After servicing, check for leakage current to prevent 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. Using an ohmmeter measure the resistance value, 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 thechassis, the reading should be between 1MΩ and 5.2Ω.When the exposed metal does not have a return path to the chassis, the reading must be .

Fig. 1

1.1.2. LEAKAGE CURRENT HOT CHECK (See Figure 1.) 1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 1.5kΩ, 10 watts resistor, in parallel with a 0.15µF 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. Should measurement is outside of the limitsspecified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned tothe customer.

2 Before Repair and AdjustmentDisconnect AC power, discharge Power Supply Capacitors C546~C549 through a 10 Ω, 1 W resistor to ground.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 230 V, 50Hz in NO SIGNAL mode should be ~410 mA.

3 Protection CircuitryThe protection circuitry may have operated if either of the following conditions are noticed: · No sound is heard when the power is turned on. · 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.

4 Handling the Lead-free Solder4.1. About lead free solder (PbF)Distinction of PbF P.C.B. :P.C.B.s (manufactured) using lead free solder will have a PbF stamp on the P.C.B.Caution: · Pb free solder has a higher melting point than standard solder. Typically the melting point is 50 - 70°F (30 - 40°C) higher.

Please use a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F(370 ± 10°C).

· Pb free solder will tend to splash when heated too high (about 1100°F/600°C). · When soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat the

soldering points with the Pb free solder until it melts enough.

SB-WA840EE

5 Connection of the Speaker Cables · Be sure to connect speaker cables before connecting the AC power supply cord. · The load impedance of any speaker used with this unit must be 4Ω. · Be sure to connect the cable from the right speaker to the right terminal and the cable from the left speaker to the left terminal.

1. Strip off the outer covering, and twist the center conductor. Make sure the bare ends of the wires are not unravelled. (If they are,twist them tight again.)

2. Insert the wire to the rear panel of the unit and close the lever.

7 Voltage Measurement and Waveform ChartNote:

· Indicated voltage values are the standard values for the unit measured by the DC electronic circuit tester (high-impedance)with the chassis taken as standard.Therefore, there may exist some errors in the voltage values, depending on the internal impedance of the DC circuit tester.

· Circuit voltage and waveform described herein shall be regarded as reference information when probing defect pointbecause it may differ from actual measuring value due to difference of Measuring instrument and its measuring conditionand product itself.

Notes:

14 Parts Location and Replacement Parts List

· Important safety notice:

Components identified by mark have special characteristics important for safety.Furthermore, special parts which have purposes of fire-retardant (resistors), high-quality sound (capacitors), low noise(resistors), etc are used.When replacing any of these components, be sure to use only manufacturer’s specified parts shown in the parts list.

· The parenthesized indications in the Remarks columns specify the areas or colour. (Refer to the cover page for area or colour)

Parts without these indications can be used for all areas. · Capacitor values are in microfarads (µF) unless specified otherwise, P= Pico-farads (pF), F= Farads. · Resistance values are in ohms, unless specified otherwise, 1K=1,000 (OHM). · The marking (RTL) indicates that the Retention Time is limited for this items. After the discontinuation of this assembly in

production, the item will continue to be available for a specific period of time. The retention period of a availability is dependenton the type of assembly, and in accordance with the laws governing part and product retention. After the end of this period, theassembly will no longer be available.

· [M] Indicates in the Remarks columns indicates parts supplied by PAVCSG.
