IMPORTANT SAFEGUARDS AND PRECAUTIONS
Prior to shipment from the factory, our products are strictly inspected for recognized product safety and electrical
codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally
important to implement the following precautions when a set is being serviced.
Safety Precautions for LCD TV Circuit
1. Before returning an instrument to the customer,
always make a safety check of the entire instrument,
including, but not limited to, the following items:
a. Be sure that no built-in protective devices are defective
and have been defeated during servicing.
(1) Protective shields are provided on this chassis to
protect both the technician and the customer.
Correctly replace all missing protective shields,
including any removed for servicing convenience.
(2) When reinstalling the chassis and/or other
assembly in the cabinet, be sure to put back in place
all protective devices, including but not limited to,
nonmetallic control knobs, insulating fishpapers,
adjustment and compartment covers/shields, and
isolation resistor/capacitor networks. Do not operate
this instrument or permit it to be operated without
all protective devices correctly installed and
functioning. Servicers who defeat safety features
or fail to perform safety checks may be liable for
any resulting damage.
b. Be sure that there are no cabinet openings through
which an adult or child might be able to insert their
fingers and contact a hazardous voltage. Such
openings include, but are not limited to, (1) spacing
between the Liquid Crystal Panel and the cabinet
mask, (2) excessively wide cabinet ventilation slots,
and (3) an improperly fitted and/or incorrectly secured
cabinet back cover.
c. Antenna Cold Check - With the instrument AC plug
removed from any AC source, connect an electrical
jumper across the two AC plug prongs. Place the
instrument AC switch in the on position. Connect one
lead of an ohmmeter to the AC plug prongs tied
together and touch the other ohmmeter lead in turn
to each tuner antenna input exposed terminal screw
and, if applicable, to the coaxial connector. If the
measured resistance is less than 1.0 megohm or
greater than 5.2 megohm, an abnormality exists that
must be corrected before the instrument is returned
to the customer. Repeat this test with the instrument
AC switch in the off position.
d. Leakage Current Hot Check - With the instrument
completely reassembled, plug the AC line cord directly
into a 120V AC outlet. (Do not use an isolation
transformer during this test.) Use a leakage current
tester or a metering system that complies with
American National Standards Institute (ANSI) C101.1
Leakage Current for Appliances and Underwriters
Laboratories (UL) 1410, (50.7). With the instrument
AC switch first in the on position and then in the off
position, measure from a known earth ground (metal
water pipe, conduit, etc.) to all exposed metal parts
of the instrument (antennas, handle brackets, metal
cabinet, screw heads, metallic overlays, control
shafts, etc.), especially any exposed metal parts that
offer an electrical return path to the chassis. Any
current measured must not exceed 0.5 milli-ampere.
Reverse the instrument power cord plug in the outlet
and repeat the test.

2. Read and comply with all caution and safety-related
notes on or inside the receiver cabinet, on the receiver
chassis, or on the Liquid Crystal Panel.
3. Design Alteration Warning - Do not alter or add to
the mechanical or electrical design of this TV receiver.
Design alterations and additions, including, but not
limited to circuit modifications and the addition of
items such as auxiliary audio and/or video output
connections, might alter the safety characteristics of
this receiver and create a hazard to the user. Any
design alterations or additions will void the
manufacturer's warranty and may make you, the
servicer, responsible for personal injury or property
damage resulting therefrom.

4. Observe original lead dress. Take extra care to
assure correct lead dress in the following areas:a.
near sharp edges,b. near thermally hot parts-be sure
that leads and components do not touch thermally
hot parts,c. the AC supply,d. high voltage, and,e.
antenna wiring. Always inspect in all areas for pinched,
out of place, or frayed wiring. Check AC power cord
for damage.
5. Components, parts, and/or wiring that appear to
have overheated or are otherwise damaged should
be replaced with components, parts, or wiring that
meet original specifications. Additionally, determine
the cause of overheating and/or damage and, if
necessary, take corrective action to remove any
potential safety hazard.
6. Product Safety Notice - Some electrical and
mechanical parts have special safety-related
characteristics which are often not evident from
visual inspection, nor can the protection they give
necessarily be obtained by replacing them with
components rated for higher voltage, wattage, etc..
Parts that have special safety characteristics are
identified by a ( # ) on schematics and in parts lists.
Use of a substitute replacement that does not have
the same safety characteristics as the recommended
replacement part might create shock, fire, and/or
other hazards. The product's safety is under review
continuously and new instructions are issued
whenever appropriate. Prior to shipment from the
factory, our products are strictly inspected to confirm
they comply with the recognized product safety and
electrical codes of the countries in which they are to
be sold. However, in order to maintain such
compliance, it is equally important to implement the
following precautions when a set is being serviced.

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: FOR CONTINUED
PROTECTION AGAINST A RISK OF
FIRE REPLACE ONLY WITH SAME
4A/125V
TYPE F601 (4.0A, 125V).
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, 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 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 peak (this corresponds to 0.5
mA. peak AC.) or more is excessive 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, 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
Schematic Diagrams
For continued protection, replacement parts must be
identical to those used in the original circuit.

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 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:
•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 1.5kΩ 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

AVIS POUR LA SECURITE
De nombreuses pièces, électriques et mécaniques,
dans les téléviseurs 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.

Instructions for Connectors
1. When you connect or disconnect the FFC (Flexible
Foil Connector) cable, be sure to first disconnect the
AC cord.
2. FFC (Flexible Foil Connector) cable should be inserted parallel into the connector, not at an angle.
Precautions for Using Lead-free Solder
1 Employing lead-free solder
Pb free mark (as shown below) indicates lead-free
solder, and is attached on the PWBs and service
manuals. For PWBs with Pb free mark, be sure to use
lead-free solder. For PWB without Pb free mark, use
standard solder. The alphabetical character following
Pb shows the type of lead-free solder.
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.

Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors may
occur due to a potential difference caused by electrostatic
charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1MΩ) that is properly
grounded to remove any static electricity that may be
charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate with
proper grounding (1MΩ) on the workbench or other
surface, where the semi-conductors are to be placed.
Because the static electricity charge on clothing will not
escape through the body grounding band, be careful to
avoid contacting semi-conductors with your clothing.

NOTE: CBA AND PWB MEANS PRINTED WIRING BOARD.
Standard Notes
Many electrical and mechanical parts in this chassis have special characteristics. These characteristics often pass
unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement components
rated for higher voltage, wattage, etc. Replacement parts that have these special safety characteristics are identified
in this manual and its supplements; electrical components having such features are identified by the mark " # " in
the schematic diagram and the parts list. Before replacing any of these components, read the parts list in this manual
carefully. The use of substitute replacement parts that do not have the same safety characteristics as specified in
the parts list may create shock, fire, or other hazards.
Note:
1. Do not use the part number shown on these drawings for ordering. The correct part number is shown in the parts
list, and may be slightly different or amended since these drawings were prepared.
2. All resistance values are indicated in ohms (K=103, M=106).
3. Resistor wattages are 1/4W or 1/6W unless otherwise specified.
4. All capacitance values are indicated in µF (P=10
5. All voltages are DC voltages unless otherwise specified.
Note of Capacitors:

ML --- Mylar Cap. PP --- Metallized Film Cap. SC --- Semiconductor Cap. L --- Low Leakage type
Temperature Characteristics of Capacitors are noted with the following:
B --- ±10% CH --- 0±60ppm/°C CSL --- +350~-1000ppm/°C
Tolerance of Capacitors are noted with the following:
Z --- +80~-20%
Note of Resistors:

ATTENTION: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE_A,_V.
2. CAUTION:
Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F601) is blown, first check to see that all components in the power supply circuit are not defective
before you connect the AC plug to the AC power supply. Otherwise it may cause some components in the power
supply circuit to fail.
3. Note:
(1) Do not use the part number shown on the drawings for ordering. The correct part number is shown in the parts
list, and may be slightly different or amended since the drawings were prepared.
(2) To maintain original function and reliability of repaired units, use only original replacement parts which are listed
with their part numbers in the parts list section of the service manual.
4. Wire Connectors
(1) Prefix symbol "CN" means "connector" (can disconnect and reconnect).
(2) Prefix symbol "CL" means "wire-solder holes of the PCB" (wire is soldered directly).
5. Note: Mark " " is a leadless (chip) component.
