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, ensure that all the protective devices such as
3
insulation barriers, insulation papers shields are properly installed.
3. After servicing, check for leakage current checks 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 the chassis, the reading
should be between 1M and 5.2 . / 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 1.5k , 10 watts resistor, in parallel with a 0.15 F
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
4
the measurement is outside of the limits specified, there is a possibility
of a shock hazard, and the equipment should be repaired and re-
checked before it is returned to the customer.
1.2. Caution for AC Cord
1.3. Before Repair and Adjustment
Disconnect AC power, discharge Power Supply Capacitors C272, C472, C501, C909, C910, C911 & C923
through a 10 , 1W resistor to ground.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid
state devices.
5
After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
- Current consumption at AC 230 V, 50 Hz in NO SIGNAL mode should be
~250 mA. (E/EG)
- Current consumption at AC 230-240 V, 50 Hz in NO SIGNAL mode
should be ~250 mA. (EB)
1.4. 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. Prevention of Electro Static Discharge (ESD) to
Electrostatically Sensitive (ES) Devices
Some semiconductor (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 semiconductor component or
semiconductor-equiped 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 equiped with ES devices, place
the assembly on a conductive surface such as aluminium foil, to
prevent electrostatic charge build up 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 remover device. Some solder removal
devices not classified as “anti-static (ESD protected)” can generate
6
electrical charge 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, 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).
3. Precaution of Laser Diode
Caution :
This product utilizes a laser diode with the unit turned "ON", invisible
laser radiation is emitted from the pick up lens. / Wavelength : 780 nm /
Maximum output radiation power from pick up : 100 W/VDE / Laser
radiation from pick up unit is safety level, but be sure the followings:
1. Do not disassemble the optical pick up unit, since radiation from
exposed laser diode is dangerous.
2. Do not adjust the variable resistor on the pick up unit. It was already
adjusted.
3. Do not look at the focus lens using optical instruments.
4. Recommend not to look at pick up lens for a long time.

4. Handling Precautions For Traverse Deck
The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused
by static electricity of clothes or human body.
So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
Handling of CD traverse deck (optical pickup)
1. Do not subject the traverse deck (optical pickup) to static electricity as
it is extremely sensitive to electrical shock.
2. The short land between the No.4 (LD) and No.5 (GND) pins on the
flexible board (FFC) is shorted with a solder build-up to prevent
damage to the laser diode.
3. Take care not to apply excessive stress to the flexible board (FFC
board) (Fig 4.1).
4. Do not turn the variable resistor (laser power adjustment). It has
already been adjusted.
Fig 4.1
Grounding for electrostatic breakdown prevention
1. Human body grounding (Fig 4.2)
Use the anti-static wrist strap to discharge the static electricity from
your body.
2. Work table grounding (Fig 4.2)
9
Put a conductive material (sheet) or steel sheet on the area where the
traverse deck (optical pickup) is placed, and ground the sheet.
Caution :
The static electricity of your clothes will not be grounded through the
wrist strap. So, take care not to let your clothes touch the traverse deck
(optical pickup).
Fig 4.2
Caution when Replacing the Optical Pickup :
The traverse has a short point shorted with solder to protect the laser
diode against electrostatics breakdown. Be sure to remove the solder
from the short point before making connections.
5. Handling the Lead-free Solder
5.1. 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 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
