SAFETY NOTICE
Many electrical and mechanical parts in LCD 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 and etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
components having such features are identified by “ å”
IMPORTANT SERVICE SAFETY PRECAUTION
ËServiceworkshouldbeperfomedonlybyqualifiedservicetechnicianswhoarethoroughlyfamiliar
withallsafetychecksandtheservicingguidelineswhichfollow:
and shaded areas in the Replacement Parts Lists 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.
WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.

TEST PROBE
•Use an AC voltmeter having with 5000 ohm per volt, or
higher, sensitivity or measure the AC voltage drop
across the resisor.
•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 and 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 0.75V peak (this corresponds to 0.5
milliamp.peak 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:
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 and 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,
and connect the DC power cable into the receiver's
DC jack. (Do not use an isolation transformer for this
test).

AVIS POUR LA SECURITE
De nombreuses pièces, électriques et mécaniques, dans
les téléviseurs présentent des caractéristiques spéciales
relatives àla sécurité, qui ne sont souvent pas évidentes
àvue. Le degréde 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
ËNe 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 àcelles utilisées dans le circuit d’origine.
L’utilisation de pièces qui n’ont pas les mêmes
caractéristiquesquelespiècesrecommandéesparl’usine,
indiquées dans ce manuel, peut provoquer des
électrocutions, incendies, radiations X ou autres acci-
dents.
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 placéentre 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
réglageetdecompartiment,lesréseauxderésistance-
capacité, 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 dans la prise CA de
110~240 V et le câble d’alimentation CC dans le jack
du moniteur. (Ne pas utiliser un transformateur pour
cet essai.)
•A l’aide de deux fils àpinces, brancher une résistance
de 1,5kΩ10 watts en paralléle 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 sensibilitéd’au moins
5000Ω/V pour mesurer la chute de tension en travers
de la résistance.
•Toucher avec la sonde d’essai les piéces 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 mesure
la chute de tension CA en-travers de la résistance.
Toutes les vérifications doivent être refaites aprés avoir
inverséla fiche du cordon d’alimentation. (Si
nécessaire, une prise d’adpatation non polarisée peut
être utilisée dans le but de terminer ces vérifications.)
Une valeur de 0.75 V RMS ou plus (correspond à0.5
mA C.A.) est excessive et implique un danger de
secousse électrique, qui devra être suppriméavant
de retourner l'appareil àl'utilisateur.

ËPrecautions for using lead-free solder
1Employing lead-free solder
“Main PWB”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.
2Using 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.
3Soldering
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.
Special attention must be paid to coils of L6500 - L6503.
