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: FO R C O N T I N U E D PROTECTION
AGAINST A RISK OF FIRE REPLACE ONLY WITH
SAME TYPE FUSE.

F701 (250V 5A)

• 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.

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

1.

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

Débrancher le récepteur avant toute réparation.

2.

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

F701 (250V 5A)
F721 (250V 2A)
F4732 (250V 2A)

VERIFICATIONS CONTRE L'INCEN-DIE ET LE
CHOC ELECTRIQUE

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

3.

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.

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 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.

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.

Closed Caption
information

Closed Captions and Digital Closed Captions

Your TV is equipped with an internal Closed Caption
decoder. It allows you to view conversations, narration
and sound effects as subtitles on your TV. Closed
Captions are available on some TV programs and on
some VHS home video tapes at the discretion of the
program provider.

Digital Closed Caption service is a new caption service
available only on digital TV programs (also at the
discretion of the service provider). It is a more flexible
system than the original Closed Caption system,
because it allows for a variety of caption sizes and font
styles. When the Digital Closed Caption service is in
use, it will be indicated by the appearance of DTVCC.

Not all programs and VHS videotapes offer closed
captions. Please look for the “ ” symbol to ensure
that captions will be shown.

In the Closed Caption system, there can be more than
one caption service provided. Each is identified by its
own number. The “CC1” and “CC2” services display
subtitles of TV programs superimposed over the
program's picture.

In the Closed Caption system, the “T1 (TEXT1)” or “T2
(TEXT2)” services display text that is unrelated to the
program being viewed (e.g., weather or news). These
services are also superimposed over the program
currently being viewed.

•

The CC button keeps a record of the last service
selected in its memory.
If the last closed caption mode (e.g. 1/5 DTVCC) you
selected is not available for the next program, or on
another channel, the closed caption service that is
available is automatically selected.
Closed Caption services that appear in parentheses will
not be stored in the CC button's memory as your last
selected service. Only services that you have selected
with the CC button are stored.

Examples:

In a case where there are two closed caption services
provided (for instance, DTVCC and CC1), and DTVCC
is displayed as your current selection, if DTVCC is not
broadcast for the next program, the other closed caption
service, CC1, will be displayed.

Four kinds of closed caption service (CC1, CC2, T1 (TEXT1),

•
T2 (TEXT2)) are potentially available, but a broadcast
may contain none or only some of these services at the
discretion of the program provider.
