SAFETY PRECAUTION
Service Manual
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.
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.
2. Disconnect AC power before servicing.
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.)
C A U T I O N : F O R C O N T I N U E D PROTECTION
AGAINST A RISK OF FIRE REPLACE ONLY WITH
SAME TYPE FUSE.
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.
F701 (250V 8A)
DVM
AC SCALE
„BEFORE RETURNING THE RECEIVER (Fire &
Shock Hazard)
1.5k ohm
10W
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.
0.15 μF
TEST PROBE
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 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.

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
SAFETY NOTICE
Many electrical and mechanical parts in LCD color television have
special safety-related characteristics.
For continued protection, replacement parts must be identical to those
used in the original circuit.
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.
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.
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 Replacement Parts
List and Schematic Diagrams.

PRECAUTIONS A PRENDRE LORS DE LA REPARATION
Ne peut effectuer la réparation qu' un technicien spécialisé qui s'est parfaitement accoutumé à toute vérification de sécurité et aux
conseils suivants.
AVERTISSEMENT
• A l'aide de deux fils à pinces, brancher une résistance de 1.5 kΩ
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.
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.
PRECAUTION: POUR LA PROTECTION CONTINUE CONTRE LES RISQUES D'INCENDIE,
REMPLACER LE FUSIBLE
• 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.)
La tension de pointe mesurèe ne doit pas dépasser 0.75V (correspondante au courant CA de pointe de 0.5mA).
Dans le cas contraire, il y a une possibilité de choc électrique qui
doit être supprimée avant de rendre le récepteur au client.
F701 (250V 8A)
VERIFICATIONS CONTRE L'INCEN-DIE ET LE
CHOC ELECTRIQUE
Avant de rendre le récepteur à l'utilisateur, effectuer les vérifications suivantes.
3. 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.
DVM
ECHELLE CA
4. 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 résistancecapacité, les isolateurs mécaniques, etc.
1.5k ohm
10W
5. S'assurer qu'il n'y ait pas de danger d'électrocution en vérifiant la
fuite de courant, de la facon suivante:
•
0.15 μF
SONDE D'ESSAI
Brancher le cordon d'alimentation directem-ent à une prise de courant de 120V. (Ne pas utiliser de transformateur d'isolation pour
cet essai).

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
AVIS POUR LA SECURITE
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, radiations X ou autres accidents.
De nombreuses pièces, électriques et mécaniques, dans les téléviseur ACL 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.

Aging time: Min. 60 minutes
2) Connect the white balance adjustment tool to the set.
[Adjustment procedure]
1) Using the remote controller, transmit the “monitor adjustment process” code.
2) Set the 6th point to the specified gradation level. With the strongest color being fixed,
turn down the R, G and B settings to their reference levels.
3) Set the 5th point to the specified gradation level. Correct the G setting (860 x 6thpoint G setting / 920) (rounded off), and make the R and B settings to their reference
levels.
4) Set the 4th point to the specified gradation level. Correct the G setting (736 x 6thpoint G setting / 920) (rounded off), and make the R and B settings to their reference
levels.
5) Set the 3rd point to the specified gradation level. Correct the G setting (512 x 6thpoint G setting / 920) (rounded off), and make the R and B settings to their reference
levels.
6) Set the 2nd point to the specified gradation level. Correct the G setting (256 x 6thpoint G setting / 920) (rounded off), and make the R and B settings to their reference
levels.
7) Set the 1st point to the specified gradation level. Correct the G setting (192 x 6thpoint G setting / 920) (rounded off), and make the R and B settings to their reference
levels.
8) With the MSET0003 command, write the adjustment values and turn off the AC
power.
* Initial R, G and B settings at point 6: Gradation level set at 920
* Initial R, G and B settings at points 1 thru 5: Corrected G setting at each point
(This is because the adjustment is made to achieve the same remainder of RGB setting /
4 at each point.)

Service Manual
[1] DESCRIPTION OF SCHEMATIC DIAGRAM
1. VOLTAGE MEASUREMENT CONDITION:
1) The voltages at test points are measured on exclusive AC adaptor
and the stable supply voltage of AC 120V. Signals are fed by a
color bar signal generator for servicing purpose and the above voltages are measured with a 20k ohm/V tester.
2. INDICATION OF RESISTOR & CAPACITOR:
RESISTOR
1) The unit of resistance "Ω" is omitted.
(K=kΩ=1000Ω, M=MΩ).
2) All resistors are ± 5%, unless otherwise noted.
(K= ± 10%, F= ± 1%, D= ± 0.5%)
3) All resistors are 1/16W, unless otherwise noted.
CAPACITOR
1) All capacitors are μF, unless otherwise noted.
(P=pF=μμF).
2) All capacitors are 50V, unless otherwise noted.
CAUTION:
This circuit diagram is original one, therefore there may be a slight
difference from yours.
SAFETY NOTES:
1) DISCONNECT THE AC PLUG FROM THE AC OUTLET
BEFORE REPLACING PARTS.
2) SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS
POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS
OPERATING.
