SAFETY PRECAUTION

IMPORTANT SERVICE SAFETY PRECAUTION

WARNING1. For continued safety, no modification of any circuit should be

attempted.

2. Disconnect AC power before servicing.

BEFORE RETURNING THE RECEIVER (Fire &Shock Hazard)Before returning the receiver to the user, perform the followingsafety checks:

3. Inspect all lead dress to make certain that leads are not pinched,and check that hardware is not lodged between the chassis andother metal parts in the receiver.

4. Inspect all protective devices such as non-metallic control knobs,insulation materials, cabinet backs, adjustment and compartmentcovers or shields, isolation resistor-capacitor networks, mechanicalinsulators, etc.

5. To be sure that no shock hazard exists, check for leakage current inthe 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 paral-leled by a 0.15F capacitor in series with all exposed metal cabinetparts and a known earth ground, such as electrical conduit or elec-trical ground connected to an earth ground.

Use an AC voltmeter having with 5000 ohm per volt, or higher, sen-sitivity or measure the AC voltage drop across the resistor.

Connect the resistor connection to all exposed metal parts having areturn to the chassis (antenna, metal cabinet, screw heads, knobsand control shafts, escutcheon, etc.) and measure the AC voltagedrop across the resistor.

All checks must be repeated with the AC cord plug connectionreversed. (If necessary, a nonpolarized adaptor plug must be usedonly for the purpose of completing these checks.)

Any reading of 0.75 Vrms (this corresponds to 0.5 mA rms AC.) ormore is excessive and indicates a potential shock hazard whichmust be corrected before returning the monitor to the owner.

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

SAFETY NOTICEMany electrical and mechanical parts in LCD color television havespecial safety-related characteristics.

These characteristics are often not evident from visual inspection, norcan protection afforded by them be necessarily increased by usingreplacement components rated for higher voltage, wattage, etc.

Replacement parts which have these special safety characteristics areidentified in this manual; electrical components having such featuresare identified by " " and shaded areas in the Replacement Parts Listand Schematic Diagrams.

For continued protection, replacement parts must be identical to thoseused in the original circuit.

The use of a substitute replacement parts which do not have the samesafety characteristics as the factory recommended replacement partsshown in this service manual, may create shock, fire or other hazards.

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the servicing guidelines which follow:

curit, qui ne sont souvent pas videntes vue. Le degr de protec-

tion ne peut pas tre ncessairement augmente en utilisant des

pices de remplacement talonnes pour haute tension, puissance,

etc.

Les pices de remplacement qui prsentent ces caractristiques sont

identifies dans ce manuel; les pices lectriques qui prsentent ces

particularits sont identifies par la marque " " et hachures dans la

liste des pices de remplacement et les diagrammes schmatiques.

Pour assurer la protection, ces pices doivent tre identiques celles

utilises dans le circuit d'origine. L'utilisation de pices qui n'ont pas

les mmes caractristiques que les pices recommandes par l'usine,

indiques dans ce manuel, peut provoquer des lectrocutions, incen-

dies, radiations X ou autres accidents.

Ne peut effectuer la rparation qu' un technicien spcialis qui s'est parfaitement accoutum toute vrification de scurit et aux

conseils suivants.

N'entreprendre aucune modification de tout circuit. C'est danger-

eux.

Dbrancher le rcepteur avant toute rparation.

Inspecter tous les faisceaux de cbles pour s'assurer que les fils

ne soient pas pincs ou qu'un outil ne soit pas plac entre le chs-

sis et les autres pices mtalliques du rcepteur.

Inspecter tous les dispositifs de protection comme les boutons de

commande non-mtalliques, les isolants, le dos du coffret, les cou-

vercles ou blindages de rglage et de compartiment, les rseaux

de rsistancecapacit, les isolateurs mcaniques, etc.

S'assurer qu'il n'y ait pas de danger d'lectrocution en vrifiant la

fuite de courant, de la facon suivante:

Brancher le cordon d'alimentation directem-ent une prise de cou-

rant de 120V. (Ne pas utiliser de transformateur d'isolation pour

cet essai).

A l'aide de deux fils pinces, brancher une rsistance de 1.5 k

10 watts en parallle avec un condensateur de 0.15F en srie

avec toutes les pices mtalliques exposes du coffret et une terre

connue comme une conduite lectrique ou une prise de terre

branche la terre.

Utiliser un voltmtre CA d'une sensibilit d'au moins 5000/V pour

mesurer la chute de tension en travers de la rsistance.

Toucher avec la sonde d'essai les pices mtalliques exposes qui

prsentent une voie de retour au chssis (antenne, coffret mtalli-

que, tte des vis, arbres de commande et des boutons, cusson,

etc.) et mesurer la chute de tension CA en-travers de la rsistance.

Toutes les vrifications doivent tre refaites aprs avoir invers la

fiche du cordon d'alimentation. (Si ncessaire, une prise

d'adpatation non polarise peut tre utilise dans le but de termin-

er ces vrifications.)

La tension de pointe mesure ne doit pas dpasser 0.75V (corre-

spondante au courant CA de pointe de 0.5mA).

Dans le cas contraire, il y a une possibilit de choc lectrique qui

doit tre supprime avant de rendre le rcepteur au client.

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:

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 dam-

age 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 solderingbit, 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 bepeeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm thesteady 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 asrequired.

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.

Lead-free wire solder for servicing

Indicates lead-free solder of tin, silver and copper. Indicates lead-free solder of tin, silver and copper.

2. Upgrading of each microprocessor software

2.1. Software version upgradeThe 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

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)

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 upgradeNOTE: 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 the same items as listed in the Main software version upgrade.

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.

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-VIDEOterminal 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 (inabilityto start).

4. After the unit startup, the system upgrade screen as shown below appears within 10-30 seconds.

5. A failure in the process will trigger the upgrade failure screen. The word NG changes to red for the item failed.

NOTE: In the event of a failure, repeat the upgrading process. If the process repeatedly fails, it is likely that the hardware is troubled.

6. Upon completion of the whole process, the upgrade success screen as shown below appears. You can check the new software version on thisscreen. The version information appears after the upgrade is complete.

7. Shut off the AC power to the unit (unplug the AC cord), and remove the SD card for version upgrade.

8. Now the software version upgrade is complete.

NOTE: When you are done with the software version upgrade, start the set, go to the top page of the adjustment process screen and check the mon-itor microprocessor software version information.

LC-32D41U/LC-32M41U/LC-40C32U Service Manual CHAPTER 7. MAJOR IC INFORMATIONS

[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 sepa-rates and decodes the compressed audio and video data to send the signals. In the visual system, the graphic processor makes it possible tooverlap subtitles and perform scaling. Digital video signals (Y, Pb and Pr, or 480I/P, 720P and 1081I) and downconverted NTSC signals (Y/C andcomposite, 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. Usingthese interfaces, the CPU controls peripheral circuits of the tuner, SD Memory Cards, CableCARDs, etc. One of the UARTs is used by the CPU toestablish communications with the monitor microcomputer in the unit, where remote control information or other data is exchanged. Another UARTis used for RS-232C serial communications to connect the unit to a PC.
