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 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 expose d metallic cabinet part on
the equipment such as screwheads, connectors, control shafts, etc. When the expose d metallic part has a return path to the
chassis, 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
.
Figure. 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 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
SA-PMX1E / SA-PMX1EB / SA-PMX1EG

SA-PMX1E / SA-PMX1EB / SA-PMX1EG
1.3. Before Repair and Adjustment
Disconnect AC power, discharge Power Supply Capacitors C500, C501, C513, C625, C626, C633, C634, C901, C900, C902 and
C909 through a 10Ω, 1W 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 230V, 50 Hz in NO SIGNAL mode should be ~300 mA (E/EG).
·Current consumption at AC 230V-240V, 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 speake r connec tion 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 handlin g 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 removal 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-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 conduc tive 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 installe d.
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).

4 Handling Precautions For Traverse Deck
The laser diode in the traverse deck (optical pickup) may break down due to potent ial 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 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. To prevent the breakdown of the laser diode, an antistatic shorting pin is inserted into the flexible board (FFC board).
3. Take care not to apply excessive stress to the flexible board (FFC board). When removing or connecting the short pin, finish
the job in as short time as possible. (Fig 4.1)
4. Do not turn the variable resistor (laser power adjustment). It has already been adjusted.
·Grounding for electrostatic breakdown prevention
1. Work table 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)
Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is place, 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).
Caution when replacing the Traverse Deck
The traverse deck 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. 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 (86°F) 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±86°F).
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)
RFKZ06D01K-----------(0.6mm 100g Reel)
RFKZ10D01K-----------(1.0mm 100g Reel)
