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, 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
ËService work should be performed only by qualified service technicians who are thor-
oughly familiar with all safety checks and the servicing guidelines which follow:
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.
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 120 volt AC outlet. (for
North America)
•Plug the AC cord directly into a 110~240 volt AC outlet.
(for Others)
•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 0.75V rms (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.

AVIS POUR LA SECURITE
De nombreuses pièces, électriques et mécaniques, dans
les téléviseurs de l ' afficharge à cristaux liquides
présentent des caractéristiques spéciales relatives à la
sécurité.
Ces caracténstiques 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
PRECAUTIONS A PRENDRE LORS DE LA REPARATION
ËLa réparation ne peut être effectuée que par un technicien spécialisé qui s'est parfaitement
accoutumé à toute vérification de sécurité et aux conseils suivants.
pièces électriques qui présentent ces particularités sont
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 ou autres accidents.
AVERTISSEMENT
1. Pour la sécurité continue, n'entreprendre aucune
modification de tout circuit.
2. Débrancher l'alimentation CA avant la réparation.
AVANT DE RENDRE LE RECEPTEUR A
L’UTILISATEUR (Incendie et choc électrique)
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 résistance-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:
•Enficher le cordon d'alimentation directement dans une
prise de 120V CA. (Pour L'Aérique du Nord)
•Enficher le cordon d'alimentation directement dans une
prise de 110-240V CA. (Pour d'autres pays)
•A l'aide de deux fils à pinces, brancher une résistance
de 1.5kΩ10 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 CA 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 doit être utilisée
dans le but de terminer ces vérifications.)
La tension de pointe mesurèe ne doit pas dépasser
0.75V RMS (correspondante au courant CA de pointe
de 0.5mA RMS). 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
"All 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.

How to upgrade the software
1Shut off the AC power (i.e. unplug the AC cord).
2Insert the SD card for version upgrade (prepared as above) into the service socket located below left of the
right-side cooling fan in the rear of the unit, in a way that the cut corner of the SD card comes at the right-
hand 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.
3While depressing the "SYSTEM RESET" button located below the RS-232C connector in the rear left side
of the unit, plug in the AC cord.
Note: While depressing the "SYSTEM RESET" button located in the rear left side of the unit, turn on the AC
power (i.e. plug in the AC cord).
Note: After the unit is started, you may release the "SYSTEM RESET" button.
4After the unit startup, the system upgrade screen as shown below appears within 20-40 seconds.
5Even 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, it is likely that the
hardware is troubled.
