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.

F701 (250V 8A), F702 (250V 2A) F4702 (250V 4A), F4701/F4703 (250V 3A 127

• 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.

PRECAUTIONS A PRENDRE LORS DE LA REPARATION

Ne peut effectuer la réparation qu' un technicien spécialisé qui s'est parfaitement accoutumé à toute vérification de sécurité et aux conseils suivants.

•

AVERTISSEMENT

N'entreprendre aucune modification de tout circuit. C'est dangereux.

Débrancher le récepteur avant toute réparation.

PRECAUTION: POUR LA PROTECTION CONTINUE CONTRE LES RISQUES D'INCENDIE, REMPLACER LE FUSIBLE

F701 (250V 8A), F702 (250V 2A) F4702 (250V 4A), F4701/F4703 (250V 3A ~ 127

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 ne soient pas pincés ou qu'un outil ne soit pas placé entre le châssis et les autres pièces métalliques du récepteur.

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.

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 kΩ 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 5000Ω/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.

LC-46D92U/LC-52D92U

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.

CHAPTER 3. ADJUSTMENT

Service Manual

[1] ADJUSTMENT PROCEDURE

The adjustment values are set to the optimum conditions at the factory before shipping. If a value should become improper or an adjustment is required due to part replacement, make an adjustment according to the following procedure.

1. After replacement of any PWB unit and/or IC for repair, please note the following.

When replacing the MAIN unit, make sure to prepare the new units loaded with updated software.

2. Upgrading of each microprocessor software

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

2.2.1 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)

2.2.2 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.)

3 – 1

LC-46D92U/LC-52D92U

2. When the formatting is over, the following window appears. Click [OK].

3. Click [Exit] to finish the formatting.

NOTE: When you are done, take out the SD card once to make sure it is finished, and then insert it again.

4. Copy the binary image file DA60UAxx.SDC (named temporarily) for version upgrade to the root directory (folder) of the SD card drive.

NOTE: In the SD card drive, do not store other folders or unrelated files, or more than one binary image files for version upgrade.

Now the SD card for version upgrade is ready.

2.2.3 Upgrading the software

1. Turn off the AC power (Unplug the AC power cord).

2. Insert the upgrading SD card (prepared as instructed above) into the service slot.

NOTE: Be careful not to insert the SD card in the wrong way. Otherwise the card may come into the set and fail to come out.

3. Turn on the AC power (Plug in the AC power cord).

4. A couple to dozen seconds after the set starts, the upgrade screen below shows up.

3 – 2

LC-46D92U/LC-52D92U

5. If any of the procedures fails, the following upgrade failure screen shows up. For the failing procedure, the “NG” marking turns red.

NOTE: In such case, try to upgrade the software again. If it still fails, the hardware may be in trouble.

6. When all the procedures are complete, the following upgrade success screen shows up. The new software version can be confirmed on screen. The version number appears when each item has been successfully upgraded. Finally the main version number appears on screen.

7. Turn off the AC power (Unplug the AC power cord). Take out the upgrading SD card.

8. Now the software has been upgraded.

NOTE: Then get the set started and call the process adjustment screen 1/26 to check the main software version.

CAUTION: 1) Do not take out and put in the SD memory card during formatting.

2) With the SD formatted, all the data stored on the medium will be deleted.

3) Do not start the SD formatting with the memory card’s WRITE PROTECT switch still on.

4) If the SD memory card format software does not recognize the SD memory card, take out and put in the SD memory card again, and click the “UPDATE” button.

5) After checking the performance, use the set under its interface environment.

6) The SD formatting is impossible on drives that are not recognized “REMOVABLE”.

2.3. Upgrading the monitor microprocessor software

2.3.1 Kit

Have the above “Upgrading the main software” kit or equivalent at hand.

2.3.2 Preparations

As discussed in “Upgrading the main software” earlier, create the SD card for upgrading the monitor microprocessor software. For this SD card, use the monitor microprocessor upgrading binary image file.

2.3.3 Upgrading procedure

To follow the monitor microprocessor software upgrading, the monitor screen upgrade progress indicator and the flashing power LED indicator can be used.

1. Turn off the AC power (Unplug the AC power cord).

2. Insert the upgrading SD card (prepared as instructed above) into the service slot at the back of the set. Insert the SD card with its logo-printed face upward (visible). Be careful not to insert the SD card in the wrong way. Otherwise the card may come into the set and fail to come out.

3. Turn on the AC power (Plug in the AC power cord).

CAUTION: Now the monitor microprocessor software starts getting upgraded. Be very careful not to turn off the power while the software is being

upgraded. Otherwise the software will fail to upgrade itself and the set will fail to get started.

3 – 3

LC-46D92U/LC-52D92U

4. A couple to dozen seconds after the set starts, the upgrade screen below shows up. The upgrade progress is indicated on screen. The power LED indicator goes out once and then starts flashing in blue. (It takes 2-3 minutes to get the monitor microprocessor software upgraded.)

5. If the procedure fails, the following upgrade failure screen shows up and the “NG” marking turns red. The power LED indicator fails to start flashing in blue. Even if the usual screen reappears in several seconds, do the procedure from Step “1” again.

NOTE: In case of failure, try to upgrade the software again. If it still fails, the hardware may be in trouble.

6. When the procedure is complete, the following upgrade success screen shows up. The new software version can be confirmed on screen. The upgrade success can also be confirmed when the power LED indicator and the OPC LED indicator start flashing alternately in blue and green, respectively. Double-check the upgrading and turn off the AC power (Unplug the AC power cord). Take out the upgrading SD card. Now the software has been upgraded.

Finally get the set started and call the process adjustment screen 1/29 to check the monitor microprocessor software version.

3 – 4

LC-46D92U/LC-52D92U

3. Entering and exiting the adjustment process mode

1) Before entering the adjustment process mode, the AV position RESET in the video adjustment menu.

2) While holding down the “VOL (–)” and “INPUT” keys at a time, plug in the AC cord of the main unit to turn on the power.

The letter “<K>” appears on the screen.

3) Next, hold down the “VOL (–)” and “CH ( )” keys at a time.

(The “VOL (–)” and “CH ( )” keys should be pressed and held until the display appears.)

Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment process mode.

When you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.

4) To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to make a forced shutdown. (When the power was turned off with the remote controller, once unplug the AC cord and plug it again. In this case, wait 10 seconds or so before plugging.)

CAUTION: Use due care in handling the information described here lest your users should know how to enter the adjustment process mode. If the

1.11. IC8101 (RH-iXB281WJZZQ)

This LSI with MPEG-2 system decoder performs back-end processing for digital broadcasting. It is equipped with a CPU (processor core: AM33-3), de scrambler (DES), transport stream de-multiplexer, 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 de scrambler. Then using the de-multiplexer, 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 down-converted 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 Cable CARD interface, etc.) and a GPIO. Using these interfaces, the CPU controls peripheral circuits of the tuner, SD Memory Cards, Cable CARDs, 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.

1.12. IC8301/8302/8303/8304 (RH-iXB765WJQZQ)

These are 256-Mb (4 Mb x 16 I/O x 4 banks) F-die DDR SDRAMs.
