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 cabinetpart on the equipment such as screwheads, connectors,control shafts, etc. When the exposed metallic part has areturn path to the chassis, the reading should be between1M and 5.2M.When the exposed metal does not have a return path to thechassis, the reading must be .
1.1.2. Leakage current hot check(See Figure 1 .)
1. Plug the AC cord directly into the AC outlet. Do not use anisolation transformer for this check.
2. Connect a 1.5k, 10 watts resistor, in parallel with a 0.15Fcapacitors, between each exposed metallic part on the setand a good earth ground such as a water pipe, as shown inFigure 1.
3. Use an AC voltmeter, with 1000 ohms/volt or moresensitivity, to measure the potential across the resistor.
4. Check each exposed metallic part, and measure thevoltage at each point.
5. Reverse the AC plug in the AC outlet and repeat each of theabove measurements.
6. The potential at any point should not exceed 0.75 voltsRMS. A leakage current tester (Simpson Model 229 orequivalent) may be used to make the hot checks, leakagecurrent must not exceed 1/2 milliampere. In case ameasurement is outside of the limits specified, there is apossibility of a shock hazard, and the equipment should berepaired and rechecked before it is returned to thecustomer.

1 Safety Precaution1.1. 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.

2 Warning2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatic Sensitive
(ES) DevicesSome semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are calledElectrostatic Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistor-sandsemiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damagecaused 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 asaluminum 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, aluminum foil or comparableconductive material).
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective materialto 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 sufficientto damage an ES device).

2.3. Service caution based on legal restrictions2.3.1. 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 thisequipment 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 (86F) more than thatof the normal solder.
Definition of PCB Lead Free Solder being usedThe 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 35030
degrees C (66286F).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%

10.3. Standard Inspection Specifications after Making RepairsAfter making repairs, we recommend performing the following inspection, to check normal operation.
No. Procedure Item to Check1 Turn on the power, and confirm items pointed out. Items pointed out should reappear.2 Insert RAM disc. The Panasonic RAM disc should be recognized.3 Enter the EE (TU IN / AV IN - AV OUT) mode. No abnormality should be seen in the picture, sound or operation.4 Perform auto recording and playback for one minute using the RAM
disc.No abnormality should be seen in the picture, sound or operation.*Panasonic DVD-RAM disc should be used when recording andplayback.
5 Model with the HDD: Perform auto recording and playback for oneminute using the HDD.
No abnormality should be seen in the picture, sound or operation.
6 If a problem is caused by a VCD, DVD-R, DVD-Video, Audio-CD, orMP3, playback the test disc.
No abnormality should be seen in the picture, sound or operation.
7 Models with SD Card Slot or DV Input Jack: In case of that thetrouble is caused by SD card and/or DV terminal.
Models with SD Card or DV Input Jack;1) SD Card: Check to be able to display and copy the picture.2) DV terminal: Check to be able to record from DVC.
8 After checking and making repairs, upgrade the firmware to thelatest version.
Make sure that [FIRM_SUCCESS] appears in the FL displays.*[UNSUPPORT] display means the unit is already updated tonewest same version. Then version up is not necessary.
9 Transfer [9][9] in the service mode setting, and initialize the servicesettings (return various settings and error information to theirdefault values. The laser time is not included in this initialization).
Make sure that [CLR] appears in the FL display.After checking it, turn the power off.
