SAFETY PRECAUTION
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 TYPE FUSE,
F7000 (250V 5A)
F7001 (250V 5A)
==BEFORE RETURNING THE RECEIVER (Fire &
Shock Hazard)
Before returning the receiver to the user, perform the following
safety checks:
3. 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.
4. 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.
5. 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.
Using two clip leads, connect a 1.5k ohm, 10 watt resistor paral-
leled by a 0.15f_F capacitor in series with all exposed metal cabinet
parts and a known earth ground, such as electrical conduit or elec-
trical ground connected to an earth ground.
Use an AC voltmeter having with 5000 ohm per volt, or higher, sen-
sitivity 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 0.75 Vrms (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.

SAFETY NOTICE
Many electrical and mechanical parts in LCD color 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 "/i',," and shaded areas in the Replacement Parts List
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.

Avant de rendre le r_cepteur a I'utilisateur, effectuer les v_rifica-
tions suivantes.
3. Inspecter tousles faisceaux de c_bles pour s'assurer que les ills
ne soient pas pinces ou qu'un outil ne soit pas place entre le chas-
sis et les autres pi_ces m6talliques du recepteur.
4. Inspecter tousles dispositifs de protection comme les boutons de
commande non-m6talliques, les isolants, le dos du coffret, les cou-
vercles ou blindages de r6glage et de compartiment, les r6seaux
de r6sistancecapacit6, les isolateurs m6caniques, etc.
5. S'assurer qu'il n'y ait pas de danger d'61ectrocution en v6rifiant la
fuite de courant, de la facon suivante:
Brancher le cordon d'alimentation directem-ent _ une prise de cou-
rant de 120V. (Ne pas utiliser de transformateur d'isolation pour
cet essai).
A I'aide de deux ills _ pinces, brancher une r6sistance de 1.5 k__
10 watts en parall_le avec un condensateur de 0.15f.LF en s@ie
avec toutes les pi_ces m6talliques expos6es du coffret et une terre
connue comme une conduite 61ectrique ou une prise de terre
branchee _ la terre.
Utiliser un voltm_tre CA d'une sensibilit6 d'au moins 5000_dV pour
mesurer la chute de tension en travers de la r6sistance.
Toucher avec la sonde d'essai les pi6ces m6talliques expos6es qui
pr6sentent une vole de retour au chassis (antenne, coffret m6talli-
que, t6te des vis, arbres de commande et des boutons, 6cusson,
etc.) et mesurer la chute de tension CA en-travers de la r6sistance.
Toutes les v@ifications doivent 6tre refaites apr6s avoir invers6 la
fiche du cordon d'alimentation. (Si necessaire, une prise
d'adpatation non polaris6e peut _tre utilis6e dans le but de termin-
er ces v@ifications.)
La tension de pointe mesur6e ne dolt pas depasser 0.75V (corre-
spondante au courant CA de pointe de 0.5mA).
Dans le cas contraire, il y a une possibilit6 de choc 61ectrique qui

PRECAUTIONS FOR USING LEAD-FREE SOLDER
='Employing lead-free solder
"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:
a a/a
Sn-Ag-Cu
Indicates lead-free solder of tin, silver and copper.
Indicates lead-free solder of tin, silver and copper.
Sn-Ag-Cu
='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 dam-
age 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.
='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.

2. Supply AC power and write the main software to IC8401 and the monitor micro-
processor software to IC2002.
3. Check that writing is normally completed and turn off the power.
CAUTION: When the USB memory is not inserted or reading error occurs, nothing
is written. (The former models have read the main software from the
writing jig. However, this model reads the main/monitor software from
the USB memory.)
Please exchange to another PWB unit when IC8401 (NAND Flash) is failure.
