SAFETY PRECAUTION
Service Manual
IMPORTANT SERVICE SAFETY PRECAUTION
Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the servicing guidelines which follow:
WARNING
1. For continued safety, no modification of any circuit should be attempted.
2. Disconnect AC power before servicing.
CAUTION: FOR CONTINUED PROTECTION AGAINST A RISK OF FIRE REPLACE ONLY WITH SAME TYPE FUSE.
AV
F701 (125V 8A), F4701, F5701 (250V 3A ~ 115
O
C)
• Use an AC voltmeter having with 5000 ohm per volt, or higher, sen­sitivity or measure the AC voltage drop across the resistor.
• Connect the resistor connection to all exposed metal parts having a return to the chassis (antenna, metal cabinet, screw heads, knobs and control shafts, escutcheon, etc.) and measure the AC voltage drop across the resistor.
All checks must be repeated with the AC cord plug connection reversed. (If necessary, a nonpolarized adaptor plug must be used only for the purpose of completing these checks.)
Any reading of 0.75 Vrms (this corresponds to 0.5 mA rms AC.) or more is excessive and indicates a potential shock hazard which must be corrected before returning the monitor to the owner.
DVM
BEFORE RETURNING THE RECEIVER (Fire & Shock Hazard)
Before returning the receiver to the user, perform the following safety checks:
3. Inspect all lead dress to make certain that leads are not pinched, and check that hardware is not lodged between the chassis and other metal parts in the receiver.
4. Inspect all protective devices such as non-metallic control knobs, insulation materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacitor networks, mechanical insulators, etc.
5. To be sure that no shock hazard exists, check for leakage current in the following manner.
• Plug the AC cord directly into a 120 volt AC outlet.
• Using two clip leads, connect a 1.5k ohm, 10 watt resistor paral­leled by a 0.15µF capacitor in series with all exposed metal cabinet parts and a known earth ground, such as electrical conduit or elec­trical ground connected to an earth ground.

SAFETY NOTICE
Many electrical and mechanical parts in LCD color television have special safety-related characteristics.
These characteristics are often not evident from visual inspection, nor can protection afforded by them be necessarily increased by using replacement components rated for higher voltage, wattage, etc.
Replacement parts which have these special safety characteristics are identified in this manual; electrical components having such features
are identified by " " and shaded areas in the Replacement Parts List and Schematic Diagrams.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
For continued protection, replacement parts must be identical to those used in the original circuit.
The use of a substitute replacement parts which do not have the same safety characteristics as the factory recommended replacement parts shown in this service manual, may create shock, fire or other hazards.

VERIFICATIONS CONTRE L'INCEN-DIE ET LE CHOC ELECTRIQUE
Avant de rendre le récepteur à l'utilisateur, effectuer les vérifica­tions suivantes.
Inspecter tous les faisceaux de câbles pour s'assurer que les fils
3. ne soient pas pincés ou qu'un outil ne soit pas placé entre le châs­sis et les autres pièces métalliques du récepteur.
4.
Inspecter tous les dispositifs de protection comme les boutons de commande non-métalliques, les isolants, le dos du coffret, les cou­vercles ou blindages de réglage et de compartiment, les réseaux de résistancecapacité, les isolateurs mécaniques, etc.
5.
S'assurer qu'il n'y ait pas de danger d'électrocution en vérifiant la fuite de courant, de la facon suivante:
Brancher le cordon d'alimentation directem-ent à une prise de cou­rant de 120V. (Ne pas utiliser de transformateur d'isolation pour cet essai).
A l'aide de deux fils à pinces, brancher une résistance de 1.5 k 10 watts en parallèle avec un condensateur de 0.15µF en série avec toutes les pièces métalliques exposées du coffret et une terre connue comme une conduite électrique ou une prise de terre branchée à la terre.
Utiliser un voltmètre CA d'une sensibilité d'au moins 5000/V pour mesurer la chute de tension en travers de la résistance.
Toucher avec la sonde d'essai les pièces métalliques exposées qui présentent une voie de retour au châssis (antenne, coffret métalli­que, tête des vis, arbres de commande et des boutons, écusson, etc.) et mesurer la chute de tension CA en-travers de la résistance. Toutes les vérifications doivent être refaites après avoir inversé la fiche du cordon d'alimentation. (Si nécessaire, une prise d'adpatation non polarisée peut être utilisée dans le but de termin­er ces vérifications.) La tension de pointe mesurèe ne doit pas dépasser 0.75V (corre­spondante au courant CA de pointe de 0.5mA). Dans le cas contraire, il y a une possibilité de choc électrique qui doit être supprimée avant de rendre le récepteur au client.

AVIS POUR LA SECURITE
De nombreuses pièces, électriques et mécaniques, dans les télévi­seur ACL présentent des caractéristiques spéciales relatives à la sé­curité, qui ne sont souvent pas évidentes à vue. Le degré de protec­tion ne peut pas être nécessairement augmentée en utilisant des pièces de remplacement étalonnées pour haute tension, puissance, etc. Les pièces de remplacement qui présentent ces caractéristiques sont identifiées dans ce manuel; les pièces électriques qui présentent ces particularités sont identifiées par la marque " " et hachurées dans la liste des pièces de remplacement et les diagrammes schématiques.
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Pour assurer la protection, ces pièces doivent être identiques à celles utilisées dans le circuit d'origine. L'utilisation de pièces qui n'ont pas les mêmes caractéristiques que les pièces recommandées par l'usine, indiquées dans ce manuel, peut provoquer des électrocutions, incen­dies, radiations X ou autres accidents.

PRECAUTIONS FOR USING LEAD-FREE SOLDER
Employing lead-free solder
• “PWBs” of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals. The alphabetical character following LF shows the type of lead-free solder.
Example:
Indicates lead-free solder of tin, silver and copper. Indicates lead-free solder of tin, silver and copper.
Using lead-free wire solder
• When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause dam­age or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 °C, we recommend you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.
Soldering
• As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 °C which is higher than the conventional lead solder by 40 °C, and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of time. However, Since the land may be peeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on and off the power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
• Be careful when replacing parts with polarity indication on the PWB silk.

Caution: Never “POWER OFF” the unit when software upgrade is ongoing. Otherwise the system may be damaged beyond recovery.
2.1. Software version upgrade
The model employs the following software.
•Main software
• Monitor microprocessor software
The main software and the monitor microprocessor software can be upgraded by using a general-purpose SD memory card.
The followings are the procedures for upgrading, explained separately for each of the main software, the monitor microprocessor software.
2.2. Main software version upgrade
Get ready before you start
• SD memory card of 32MB or higher capacity
• PC running on Windows 98/98SE/ME/2000/XP operating system
• SD memory card reader/writer with USB connectivity.
• SD memory card formatting software
(Downloadable at http://panasonic.jp/support/audio/sd/download/sd_formatter_e.html)
Preparations
To upgrade the main software, it is necessary to get ready the SD card for version upgrade before you start.
Follow the steps below and create the SD card for version upgrade.
1. Insert the SD card into the SD card reader/writer. Start the SD card formatting software. Click [Format]. (When you have the drive options, select the drive where the SD card is inserted before you proceed.)

2.3. Monitor microprocessor software version upgrade
NOTE: If “Monitor version” in the process menu is “2.00M”, the monitor microprocessor software can not be rewritten (because IC2002 has been
replaced with the mask type).
Get ready before you begin
Get ready the same items as listed in the “Main software version upgrade”.
Preparation
Create the SD card for monitor microprocessor software version upgrade in the same manner as explained in the “Main software version upgrade”. Copy the binary image file M150Mxxx.SDC (named temporarily) for monitor microprocessor software version upgrade to the SD card drive.
How to upgrade the software
1. Shut off the AC power to the unit (i.e. unplug the AC cord).
2. Insert the SD card for version upgrade (prepared as above) into the service socket located lower side from center at terminals, above S-VIDEO terminal in the rear of the unit, in a way that the cut corner of the SD card comes at the upper side.
NOTE: If the SD card is inserted in a wrong way, the card will go deep inside the unit beyond retrieval. Take due care to insert the SD card correctly.
3. Turn on the AC power (i.e. plug in the AC cord).
CAUTION: The moment this operation is done, the upgrading of the monitor microprocessor software starts. While the upgrade is ongoing,
never power off the unit. Otherwise the upgrade will fail and the system may have a serious damage beyond recovery (inability to start).
4. After the unit startup, the system upgrade screen as shown below appears within 10-30 seconds.

CHAPTER 7. MAJOR IC INFORMATIONS
Service Manual
[1] MAJOR IC INFORMATIONS
• IC8101 (RH-iXB145WJQZQ)
An LSI of a MPEG-2 system decoder that performs back-end processing for digital broadcasting. This is equipped with a CPU (processor core: AM33-3), descrambler (DES), transport stream demultiplexer, video decoder (MPEG-2 MP @ HL compatible), graphic processor, audio decoder (AC3 compatible), and an NTSC video encoder.
After receiving transport stream from the tuner, the LSI decrypts pay-TV broadcasts with the descrambler. Then using the demultiplexer, it sepa­rates and decodes the compressed audio and video data to send the signals. In the visual system, the graphic processor makes it possible to overlap subtitles and perform scaling. Digital video signals (Y, Pb and Pr, or 480I/P, 720P and 1081I) and downconverted NTSC signals (Y/C and composite, or 480I) can be sent simultaneously. As for the audio system, decoded AC3 audio can be overlapped with sound effects.
The LSI also contains various interfaces (I2C x 2, UART x 3, an SD Memory Card interface, a CableCARD interface, etc.) and a GPIO. Using these interfaces, the CPU controls peripheral circuits of the tuner, SD Memory Cards, CableCARDs, etc. One of the UARTs is used by the CPU to establish communications with the monitor microcomputer in the unit, where remote control information or other data is exchanged. Another UART is used for RS-232C serial communications to connect the unit to a PC.

CHAPTER 10. SCHEMATIC DIAGRAM
Service Manual
[1] DESCRIPTION OF SCHEMATIC DIAGRAM
1. VOLTAGE MEASUREMENT CONDITION:
1) The voltages at test points are measured on exclusive AC adaptor and the stable supply voltage of AC 120V. Signals are fed by a color bar signal generator for servicing purpose and the above voltages are measured with a 20k ohm/V tester.
2. INDICATION OF RESISTOR & CAPACITOR:
RESISTOR
1) The unit of resistance "" is omitted.
(K=k=1000, M=M).
2) All resistors are ± 5%, unless otherwise noted.
(K= ± 10%, F= ± 1%, D= ± 0.5%)
3) All resistors are 1/16W, unless otherwise noted.
CAPACITOR
1) All capacitors are µF, unless otherwise noted.
(P=pF=µµF).
2) All capacitors are 50V, unless otherwise noted.
CAUTION:
This circuit diagram is original one, therefore there may be a slight difference from yours.
SAFETY NOTES:
1) DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE REPLACING PARTS.
2) SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OPERATING.
IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH " " ( ) ARE IMPORTANT FOR MAINTAINING THE SAFETY OF THE SET. BE SURE TO REPLACE THESE PARTS WITH SPECIFIED ONES FOR MAIN­TAINING THE SAFETY AND PERFORMANCE OF THE SET.
AVIS DE SECURITE IMPORTANT:
LES PIECES MARQUEES " " ( ) SONT IMPOR­TANTES POUR MAINTENIR LA SECURITE DE L'APPAREIL. NE REMPLACER CES PIEDES QUE PAR DES PIECES DONT LE NUMERO EST SPECIFIE POUR MAINTENIR LA SECURITE ET PROTEGER LE BON FONCTIONNEMENT DE L'APPAREIL.
