1. Safety Precaution
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
the exposed metallic part has a return path to the chassis, 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
2

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 milliampere. In
case a measurement is outside 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.
2. Warning
2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatic Sensitive
(ES) Devices
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such
components commonly are called Electrostatic Sensitive (ES) Devices. Examples of typical ES devices
are integrated circuits and some field-effect transistor-sand semiconductor "chip" components. The
following techniques should be used to help reduce the incidence of component damage caused by
electrostatic discharge (ESD).
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 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 aluminum 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
3

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, aluminum 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 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 sufficient to damage an ES device).

2.3. Service caution based on legal restrictions
2.3.1. 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.
5

- 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)
Note
* Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%
2.4. How to replace the Lithium Battery
REPLACEMENT PROCEDURE
1. Remove the Top case, Front Panel, RAM/Digital P.C.B. Module, DV
Jack, Rear Panel, Front (L) P.C.B. and Main P.C.B. by referring the
Disassembling Procedure.
2. Unsolder the Lithium Batteries: B7501 and then replace it into new one.
( As shown in 13.2.4. The Main P.C.B. )
NOTE:
The lithium battery is a critical component. ( Type No.: CR2354-1GUFE Manufactured by Panasonic.)
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in equipment designed specifically for its use.
Replacement batteries must be of the same type and manufacture.
They must be fitted in the same manner and location as the original battery, with the correct polarity
contacts observed.
Do not attempt to re-charge the old battery or re-use it for any other purpose.
It should be disposed of in waste products destined for burial rather than incineration.
