4. After servicing, see to it that all the protective devices
such as insulation barriers, insulation papers shields are
properly installed.
5. After servicing, make the following leakage current
checks to prevent the customer from being exposed to
shock hazards.

1.2. 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 metal- Figure. 1
lic cabinet part on the equipment such as screwheads,
connectors, control shafts, etc. When the exposed metal-
lic part has a return path to the chassis, the reading
should be between 1 MΩ and 5.2 MΩ. When the exposed
metal does not have a return path to the chassis, the
reading must be infinity.

2 Warning
2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically
Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec-
trostatically 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 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 alumi-
num 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 antistatic solder removal device. Some solder removal devices not classified as “antistatic (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 compara-
ble 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 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) suf-
ficient to damage an ES device).

Check for the ASTA mark or the BSI mark on the body of the

If the plug contains a removable fuse cover you must ensure

that it is refitted when the fuse is replaced.
If you lose the fuse cover, the plug must not be used until a
replacement cover is obtained.
A replacement fuse cover can be purchased from your local 2.3.2.3. How to Replace the Fuse
Panasonic Dealer. 1. Remove the Fuse Cover with a screwdriver.

If the fitted moulded plug is unsuitable for the socket outlet in

your home then the fuse should be removed and the plug cut
off and disposed of safety.
There is a danger of severe electrical shock if the cut off plug is
inserted into any 13-ampere socket.

If a new plug is to be fitted please observe the wiring code as

shown below.
If in any doubt, please consult a qualified electrician. 2. Replace the fuse and attach the Fuse cover.

2.4. How to Replace the Lithium Battery
2.4.1. Replacement Procedure
1. Remove the SIDE R OPERATION P.C.B.. (Refer to Disassembly Procedures.)
2. Remove the Lithium battery (Ref. No. “B6951” at foil side of SIDE R OPERATION P.C.B.) and then replace it into new one.

NOTE:
This Lithium battery is a critical component.
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in requirement designed specifically for its use.
Replacement batteries must be of 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.

NOTE:
Above caution is applicable for a battery pack which is for HC-X1000 series, as well.

3 Service Navigation
3.1. Introduction
This service manual contains technical information, which allow service personnel’s to understand and service this model.
Please place orders using the parts list and not the drawing reference numbers.
If the circuit is changed or modified, the information will be followed by service manual to be controlled with original service manual.

3.2. 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.
Distinction of P.C.B. 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 P.C.B. 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 P.C.B. 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°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.
SVKZ000001-----------(0.3mm 100g Reel)
SVKZ000002-----------(0.6mm 100g Reel)
SVKZ000003-----------(1.0mm 100g Reel)
Note
* Ingredient: Tin (Sn) 96.5%, Silver (Ag) 3.0%, Copper (Cu) 0.5%. (Flux cored)

3.3. How to Define the Model Suffix (NTSC or PAL model)
There are four kinds of HC-X1000.
• a) HC-X1000 (Japan domestic model)
• b) HC-X1000PP
• c) HC-X1000E/EE
• d) HC-X1000GC
What is the difference is that the “INITIAL SETTING” data which is stored in Flash ROM mounted on Main P.C.B..

3.3.1. Defining methods:

To define the model suffix to be serviced, refer to the rating label and caution label which are putted on the Unit.

NOTE:
After replacing the MAIN P.C.B., be sure to achieve adjustment.

8
3.4. Baking of replacement IC and defective P.C.B.
When replacing the CSP/BGA/QFN type IC mounted on the P.C.B., the problem of IC crack or foil pattern breaking in the P.C.B.
might sometimes occur by rapid heating.
In order to improve the success rate of IC replacement for repair, it would be required to work out baking of replacement
IC and defective P.C.B. before replacing IC.
Please refer the way of baking as follows.
Replacement IC and defective P.C.B. must be put in the heater together.
• Baking temperature and time (Hour)
80°C / 24 hour

9.1.1. About Light Box
When using VFK1164TDVLB Light Box
If using VFK1164TDVLB Light Box, remove the lens connection ring by loosing thumbscrew and three hexagon screws.

* RFKZ0523 Light Box has no lens connection ring.

How to remove the Front Hood

In order to utilize maximum of the diffusing surface of light box, some adjustment items need the distance between diffusing
surface of light box and camera body becomes several cent-meters.
Before the adjustments, remove the front hood of light box following steps below.

[ For VFK1164TDVLB Light Box ]

[ For RFKZ0523 Light Box ]
