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 " å"

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.

CAUTION: FOR CONTINUED PROTECTION AGAINST A RISK OF FIRE REPLACE ONLY WITH SAME TYPE FUSE. F701 (2A, 250V), F702 (1A, 250V)

WARNING

1. 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 following safety checks:

1. 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.

2. 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.

3. To be sure that no shock hazard exists, check for leakage current in the following manner.

» Plug the AC cord directly into a 110~240 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.

» 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.

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:

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

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.

identifiées par la marque " å " 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.

AVERTISSEMENT

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

2. Débrancher le récepteur avant toute réparation.

VERIFICATIONS CONTRE L'INCEN-DIE ET LE CHOC ELECTRIQUE

Avant de rendre le récepteur à l'utilisateur, effectuer les vérifications suivantes.

1. 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.

2. 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.

3. 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 110-240V. (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.) Tous les courants mesurés ne doivent pas dépasser

0.5 mA. Dans le cas contraire, il y a une possibilité de choc électrique qui doit être supprimée avant de rendre le récepteur au client.

Precautions for using lead-free solder

1 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:

2 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.

3 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.

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

ADJUSTMENT PROCEDURE

This section describes the adjustment procedures which should be followed after replacement of faulty PWB (unit), with special emphasis on the precautions to be taken after replacement of Main Unit (DUNTKC619) or CPU Unit (DUNTKC427).

[Replacement of faulty CPU Unit]

1. Adjustment data are stored in the Main Unit. Therefore, no adjustment is needed after replacement of the CPU Unit.

[Replacement of faulty Main Unit]

1. A new Main Unit has no adjustment data. Therefore, all items need to be adjusted.

[Replacement of faulty IC2102 inside Main Unit]

1. A new IC2102 has no adjustment data. However, the data stored in the CPU Unit are automatically recognized and loaded. Therefore, no adjustment is necessary.

Important * Be sure to follow the step below.

[Precaution after PWB replacement or adjustment]

1. After replacement of PWB or adjustment of each part, set "KEY WRITE" to "ON" which is shown in the adjustment OSD menu (Page 2/15). Then press "Enter" and reboot the system.

Page 17

TU-GA1U-S TU-GAD

[Precaution after adjustment] * Be sure to follow the step below.

1. After adjustment of each part, select "KEY WRITE" in the adjustment OSD menu (Page 2/15) and set it to "ON" using the "VOL (+)/(–)" key. Then press "Enter" and reboot the system.

[Entering the process adjustment mode]

1) Connect the Display and the AVC system using the system cable. Plug the power cable of each unit into a wall outlet. Power up the system using the power switch of the remote controller or the main unit.

2) Enter the standby mode using the remote controller or the main unit switch. (Both the power LED of the Display and that of the AVC system light up in red.)

3) Press "Power" switch of the Display and shut off the power.

4) While simultaneously pressing the "VOL (–)" key and "INPUT" key of the Display, press "Power" switch of the Display and turn on the power. (Keep pressing the "VOL (–)" and "INPUT" keys until the specific display appears on the screen.) If you have failed (only the ordinary startup display appeared), try this step again.

5) Make sure that a K mark is displayed in the top left of the screen.

6) Simultaneously press the "VOL (–)" key and the "CH(Ù)" key of the Display. Several blue text lines appearing on the screen indicate the successful entry into the process adjustment mode.

[Exiting the process adjustment mode]

1) You can exit the process adjustment mode by pressing "Power" switch of the Display and shutting off the power.

[Remote controller key operation]

Channel up/down keys: Moves selection line by line (up/down). Volume up/down keys: Changes setting of the selected line (+1/-1). Cursor up/down keys: Navigates the page (previous/next). Cursor right/left keys: Changes setting of the selected line (+10/-10). Input: Cycles the input. (TUNER → BSD → INPUT1 → INPUT2 → INPUT 3 → INPUT4 → INPUT5)

Enter: Executes the functions. * With the necessary input signals being fed, the input switches itself after the relevant adjustment gets

started. Supply the video and component signals to INPUT1.

[Others]

* Viewing factory settings (backup data)Select EEP RECOVER in the adjustment OSD menu (Page 12/12). Using "VOL (+)/(–)" key, change the setting from "OFF" to "ON". Then press "ENTER" key.

Caution: Use due care in handling the information described here lest your users should know how to

enter the process adjustment mode. If the settings are tampered in this mode, unrecoverable system damage may result.

HOW TO UPGRADE THE INTERNAL PROGRAM

The model employs the following software.

» Main software (AVC System) » Monitor microprocessor software (Display) » Card microprocessor software

The main software and the monitor microprocessor software can be upgraded by using a general-purpose SD memory card, while the card microprocessor software by using a PC card. The followings are the procedures for upgrading, explained separately for each of the main software, the monitor microprocessor software and the card microprocessor software.

Main software version upgrade

Get ready before you start

» SD memory card of 8MB or higher capacity » PC running on Windows 98/98SE/ME/2000/XP operating system » SD memory card reader/writer with USB connectivity, PC card adapter » SD memory card formatting software

(Downloadable at http://panasonic.jp/support/audio/sd/download/sd_formatter.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.)

Page 37

TU-GA1U-S TU-GAD

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 KA1UAxxx.SDC (named tentatively) for version upgrade to the root directory

(folder) of the SD card drive. Note : In the SD card drive, do not put other folders or unrelated files, or more than one binary image files

for version upgrade.

5 Now the SD card for version upgrade is ready.

Page 38

TU-GA1U-S TU-GAD

How to upgrade the software

Software upgrading can be done regardless of whether a dedicated display is connected or not. You can view the progress on the dedicated display if it is connected. When such display is not used, see the power LED on the AVC System which blinks according to the status of upgrading. It should be noted that, unlike the digital model, the progress of upgrading does not appear on the screen of the TV set connected to the video output terminal of the AVC System.

1 Shut off the AC power to the AVC System (i.e. unplug the AC power cable). 2 Insert the SD card for version upgrade (prepared as above) into the service socket below the CENTER

CHANNEL INPUT terminal in the rear of the AVC System, keeping the cut corner of the SD card at the right-hand side. Note : If the SD card is inserted with wrong orientation, the card will go deep inside the set beyond retrieval.

Use due care to insert the SD card correctly.

3 While depressing the SYSTEM RESET button in the front of the AVC System, turn on the AC power (i.e.

plug in the AC power cable). Note : After the AVC System is started, you may release the SYSTEM RESET button.

4 After the AVC System startup, the system upgrade screen as shown below appears in several to 10-odd

seconds.

5 Even a single failure in the process will trigger the upgrade failure screen as shown below. 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, the hardware

failure is likely.

6 Upon completion of the whole process, the upgrade success screen as shown below appears. You can

check the new software version on this screen. The version information appears after the upgrade is complete.

7 Shut off the AC power to the AVC System (unplug the AC power cable), 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

process adjustment screen and check the main software version information.

Monitor microprocessor software version upgrade

Get ready before you begin

Get ready the same items as listed in the "Main software version upgrade". In addition, the display unit whose software is to be upgraded and the AVC System unit should also be ready.

Preparations

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 for monitor microprocessor software version upgrade to the SD card drive.

How to upgrade the software

The software upgrade is performed in the environment where the AVC System is connected to the display unit whose software is to be upgraded. During the monitor microprocessor software version upgrade, the progress of upgrading will appear neither on the display screen nor on the screen of the TV set connected to the monitor output terminal of the AVC System. The upgrading status is seen by the blinking of the display side power LED indicator. 1 Connect the display to the AVC System correctly. Turn on the AC power of each unit (plug in the AC power

cable).

2 Turn on the main power switch (not the receiver power switch) of the display beforehand. 3 Shut off the AC power to the AVC System (i.e. unplug the AC power cable). 4 Insert the SD card for version upgrade (prepared as above) into the service socket below the CENTER

Use due care to insert the SD card correctly.

5 While depressing the SYSTEM RESET button in the front of the AVC System, turn on the AC power (i.e.

plug in the AC power cable). Note : After the AVC System is started, you may release the SYSTEM RESET button.

Caution!! The moment this operation is done, the upgrading process of the monitor microprocessor software starts. While the upgrade is ongoing, never turn off the power to the display or the AVC System. Otherwise the upgrade will fail and the system may be damaged seriously beyond recovery (inability of the display unit startup).

6 After the AVC System startup, the display side power LED starts blinking in green in several to 10-odd

seconds.

7 Wait until the display side power LED stops blinking, the AVC System restarts automatically, and the

normal startup screen appears on the display (it will take 2-3 minutes).

8 Shut off the AC power to the AVC System (unplug the AC power cable), and remove the SD card for

version upgrade.

9 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

process adjustment screen and check the monitor microprocessor software version information.

Card microprocessor software version upgrade

1 When the set is turned on, unplug the AC power cable from the outlet for forced shutdown. 2 Insert a new microprocessor software card into the PC card slot. 3 Plug the AC power cable into the outlet. 5 Press the Menu button and select the card mode. 5 The card microprocessor program is automatically loaded from the PC card. 6 When the loading is over, "Finished" message appears. 7 Unplug the AC power cable from the outlet for forced shutdown.
