IMPORTANT SERVICE SAFETY PRECAUTION
Ë
Service work should be perfomed only by qualified ser vice 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 A GAINST A RISK OF
FIRE REPLACE ONLY WITH SAME
TYPE F3701 (2.0A, 125V), F3702
A V
(1.6A, 125V), F6500 (1.6A, 125V)
AND F6501 (1.6A, 125V) FUSE.
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 110~240 volt A C outlet,
and connect the DC power cable into the receiver's
DC jack. (Do not use an isolation transformer for this
test).
• Using two clip leads, connect a 50k 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 ha ving 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, 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 A C .) or more is e xcessive and indicates
a potential shock hazard which must be corrected
before returning the monitor to the owner .

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 , w attage , etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
and shaded areas in the
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.
components having such features are identified by “ å”

accoutumé à toute vérification de sécurité et aux conseils suivants.
AVERTISSEMENT
conduite électrique ou une prise de terre branchée à la
terre.
1. N'entreprendre aucune modification de tout circuit.
C'est dangereux.
2. Débrancher le récepteur avant toute réparation.
• 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.)

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:
L Fa
Indicates lead-free solder of tin, silver and copper.
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 40ºC, we recommend
you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldening
bit, contact our service station or service ranch 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 wettabillty, 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 excoeded, remove the bit from the PWB as soon as y ou conurm the steady soldering
condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to tum 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.
Becareful when replacing parts with polarity indication on the PWB silk.
