SAFETY PRECAUTION
IMPORTANT SERVICE SAFETY PRECAUTION
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:
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 110-240 volt 50/60Hz 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.
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.
Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the
servicing guidelines which follow:
CAUTION: FOR CONTI N U E D PROTECTION
AGAINST A RISK OF FIRE REPLACE ONLY WITH
SAME TYPE FUSE.
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.
Ne peut effectuer la réparation qu' un technicien spécialisé qui s'est parfaitement accoutumé à toute vérification de sécurité et aux
conseils suivants.
N'entreprendre aucune modification de tout circuit. C'est dangereux.
Débrancher le récepteur avant toute réparation.
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 110-240V 50/60Hz. (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.

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 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.
Lead-free wire solder for servicing
Indicates lead-free solder of tin, silver and copper.Indicates lead-free solder of tin, silver and copper.
The HDCP-KEY ROM shall be protected and managed for its information inside. In servicing this ROM, therefore, take the following information protection/management measures.
1) When disposing of the component parts and PWBs, destruct the IC itself in a proper way.
(For repairing or replacing the component parts and PWBs as well as clearing those in stock)
2) In storing the component parts, protect and manage them against theft and disclosure.
(For storing the service parts, service units, etc.)
