1 Before Use (Caution)

Be sure to disconnect the mains cord before adjusting the voltage selector.

Use a minus(-) screwdriver to set the voltage selector (on the rear panel) to the voltage setting for the area in which the unit will
be used. (If the power supply in your area is 117V or 120V, set to the “127V” position.)

Note that this unit will be seriously damaged if this setting is not made correctly. (There is no voltage selector for some countries,
the correct voltage is already set.)

2 Before Repair and Adjustment

Disconnect AC power, discharge Power Supply Capacitors C5815, C5818, C9513, C9533, C9534, C9816 and C9817 through a
10Ω, 5W 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 consum ption at AC 100/110V at 50/60 Hz & AC 240V at 50Hz in NO SIGNAL (vol. min, at CD mode) should be ~500mA
.

3 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 speake r 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 Safety Precautions

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

4.1.1. 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 1MΩand 5.2MΩ.

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

.

Figure 1

4.1.2. 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 capacitor, 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 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.

5 Prevention of Electro Static Discharge (ESD) to

Electrostatically Sensitive (ES) Devices

Some semiconducto r (solid state) devices can be damaged easily by 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 electro static discharge (ESD).

1. Immediately before handling any semiconducto r component or semiconductor-equipped assembly, drain off any ESD on your
body by touchin g 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 build up or exposu re of the assembly.

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

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

5. Do not use freon-propelle d chemicals. These can generate electrical charges sufficie nt 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, 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 body 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).

6 Handling the Lead-free Solder

6.1. 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

·

use a high temperature soldering iron. In case of 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).

· W hen 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.

solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please

8 Cautions to be taken when handling Optical Pickup

The laser diode used inside optical pickup could be destroyed due to static electricity as a potential difference is caused by
electrostatic load discharged from clothes or human body. Handling the parts carefully to avoid electrostatic destruction during
repair.

8.1. Handling Optical Pickup

1. Do not impact on optical pickup as the unit structurally uses an extremely precise technology.

2. Short-circuit the flexible cable of optical pickup remove from the circuit board using a short-circuit pin or clip in order to prevent
laser diode from electrostatic destruction (Refer to Fig. 8.1 and Fig. 8.2)

3. Do not handle flexible cables forcibly as this may cause snapping. Handle the parts carefully (Refer to Fig. 8.1)

4. A new optical pickup is equipped with an anti-static flexible cable. After replacing and connecting to the flexible board, cut the
anti-static flexible cable. (Refer to Fig. 8.1)

Fig. 8.1

8.2. Replacing Precautions for Optical Pickup Unit

DVD/CD Optical Pickup

The optical pickup by which part supply was carried out attaches the short clip to the flexible board for laser diode electrostatic
discharge damage prevention. Please remove the short clip and be sure to check that the short land is open, before connecting.
(Please remove solder, when the short land short-circuits.)

8.3. Grounding for Preventing Electrostatic Destruction

1. Human body grounding

Use the anti-static wrist strap to discharge the static electricity accumulated in your body. (Refer to Fig. 8.2)

2. Work place grounding

Place a conductive material (conductive sheet) or iron board where optical pickup is placed . (Refer to Fig. 8.2)

Note :

Keep your clothes away from optical pickup as wrist strap does not release the static electricity charged in clothes.

· The voltage value and waveforms are the reference voltage

of this unit measured by DC electronic voltmeter (high
impedance) and oscilloscope on the basis of chassis.
Accordingly, there may arise some error in voltage values
and waveforms depending upon the internal impedance of
the tester or the measuring unit.

· Importance safety notice :

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

Caution !

IC, LSI and VLSI are sensitive to static electricity.
