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 (8A, 125V)

• 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.

F4701, F5701 (3A~, 250V, 115 C)

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

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

7. Débrancher le récepteur avant toute réparation.

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

F701 (8A, 125V),
F4701, F5701 (3A~, 250V, 115 C)

VERIFICATIONS CONTRE L'INCEN-DIE ET LE

CHOC ELECTRIQUE

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

8. 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.

9. 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.

10.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 0.15 F en série avec
toutes les pièces métalliques exposées du coffret et une terre con­nue comme une conduite électrique ou une prise de terre branchée
àlaterre.

• 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.)
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 réndre le recepteur 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:

L Fa

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

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

L F a/a

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.

2.3. Monitor microprocessor software version upgrade

NOTE: If "Monitor version" in the process me nu 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 s ystem may have a serious damage beyond recov ery (inability
to 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 sho wn 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 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.

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 processin g 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.
