IMPORTANT SERVICE SAFETY PRECAUTION
Ë
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

AND F6501 (1.25A, 250V) 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 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.
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
å" and shaded areas in the
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.
components having such features are identified by "

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 " 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

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 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.

ADJUSTING PROCEDURE OF EACH SECTION
The best adjustment is made before shipping. If any position deviation is found or after part replace is performed, adjust
as follows.
1.Preparation for Adjustments
Use the exclusive-use AC adapter or stable DC power supply.
AC adapter: UADP-A009WJPZ
DC power supply: 12 ± 0.5V
2.Special mode setting procedure
(1)After initialization of E2PROM the mode is changed to the adjustment mode.
[Procedure]
Connect TP2001 and TP2002 to GND, and turn on the power.
[Description]
» The initialization of microprocessor is as follows.
» AV position, DAC data, G/A data, sound processor data, and video chroma data adjustment values are taken
as defaults.
(2)Adjustment mode
[Procedure]
Short-circuit TP2001 to GND, and turn on the power.
Or short-circuit TP2002 to GND, and turn on the power.
Or holding down the "TV/VIDEO" key and "MENU" key, turn on the main power, and simultaneously press the
(inspection process) "CH (Ù)" key and "VOL(–) " key to change the mode to the adjustment mode.
[Description]
The manual adjustment or adjustment through communication with the automatic machine is performed.
(3)Shipping setting mode
[Procedure]
Holding down the "TV/VIDEO" key and "MENU" key, turn on the main power, and simultaneously press the
(inspection process) "CH (ù)" key and "VOL(+)" key to change the mode to the shipping setting mode.
Note: Keep it in mind to turn off the power immediately. If any key-in is accidentally made, the setting will be
canceled.
[Description]
User adjustment and other values are taken as defaults.
If TV is indicated as SETTING COMPLETE, setting has been completed.
3.Cancel of special mode

on the setting of this point.)
1. Adjust the "B+ Adj" value to
5.0±0.02V with R3714. Make exact
adjustment of the 5.00V level because it will be the reference for all
the other supply voltages. Be sure to
make this adjustment together with
the main PWB (digital PWB). During
the adjustment, be also careful not to
allow the voltage at pin (2) of P3701
to go above 5.3 V.
1. Select "INCH SIZE" and adjust to
