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, make 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
3

the exposed metallic part has a return path to thechassis, 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 .
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 1.5k , 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 mu3st not exceed 1/2 milliamp. In case
a measurement is outsideof 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.
2. PREVENTION OF ELECTRO STATIC DISCHARGE
(ESD) TO ELECTROSTATICALLY 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 transistorsand semiconductor "chip" components.
The following techniques should be used to help reduce the incidence of component damage caused
by electro static discharge (ESD).
4

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 dischargingESD 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 alminum 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, alminum foil or comparableconductive 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 hamless 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 todamage an ES device).

4.1. 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°C (86°F) more than that of the normal solder.
Definition of PCB Lead Free Solder being used
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
6

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°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)
Note
* Ingredient: tin (Sn) 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt
(Co) / Germanium (Ge) 0.1 to 0.3%
5. PREVENTION OF STATIC ELECTRICITY DISCHARGE
The laser diode in the traverse unit (optical pickup) may brake down due to static electricity of clothes
or human body. Use due caution to electrostatic breakdown when servicing and handling the laser
diode.
5.1. 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.
5.1.1. Worktable grounding
1. Put a conductive material (sheet) or iron sheet on the area where the
optical pickup is placed, and ground the sheet.
5.1.2. Human body grounding
1. Use the anti-static wrist strap to discharge the static electricity form
your body.
5.1.3. Handling of optical pickup
1. To keep the good quality of the optical pickup maintenance parts
during transportation and before installation, the both ends of the laser
diode are short-circuited. After replacing the parts with new ones,
7

remove the short circuit accordingto the correct procedure. (See this
Technical Guide.)
2. Do not use a tester to check the laser diode for the optical pickup.
Failure to do so will damage the laser diode due to the power supply in
the tester.
5.2. Handling Precautions for Traverse Unit (Optical Pickup)
1. Do not give a considerable shock to the traverse unit (optical pickup)
as it has an extremely high-precise structure.
2. When replacing the optical pickup, install the flexible cable and cut its
short land with a nipper. See the optical pickup replacement procedure
in this Technical Guide. Before replacing the traverse unit, remove the
short pin for preventingstatic electricity and install a new unit. Connect
the connector as short times as possible.
3. The flexible cable may be cut off if an excessive force is applied to it.
Use caution when handling the cable.
4. The half-fixed resistor for laser power adjustment cannot be adjusted.
Do not turn the resistor.
