Service Manual

SAFETY PRECAUTION

IMPORTANT SERVICE SAFETY PRECAUTION

WARNING

1. For continued safety, no modification of any circuit should be

attempted.

2. Disconnect AC power before servicing.

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 0.15µF 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 " " 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.

Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the

servicing guidelines which follow:

CAUTION: FO R C O N T I N U E D PROTECTION

PRECAUTIONS A PRENDRE LORS DE LA REPARATION

De nombreuses pièces, électriques et mécaniques, dans les télévi-

seur ACL présentent des caractéristiques spéciales relatives à la sé-

curité, qui ne sont souvent pas évidentes à vue. Le degré de protec-

tion 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. 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, incen-

dies, radiations X ou autres accidents.

AVERTISSEMENT

•

Ne peut effectuer la réparation qu' un technicien spécialisé qui s'est parfaitement accoutumé à toute vérification de sécurité et aux

conseils suivants.

N'entreprendre aucune modification de tout circuit. C'est danger-

eux.

Débrancher le récepteur avant toute réparation.

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 châs-

sis et les autres pièces métalliques du récepteur.

Inspecter tous les dispositifs de protection comme les boutons de

commande non-métalliques, les isolants, le dos du coffret, les cou-

vercles ou blindages de réglage et de compartiment, les réseaux

de résistancecapacité, les isolateurs mécaniques, etc.

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 cou-

rant de 120V. (Ne pas utiliser de transformateur d'isolation pour

cet essai).

A l'aide de deux fils à pinces, brancher une résistance de 1.5 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.

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 métalli-

que, 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 termin-

er ces vérifications.)

La tension de pointe mesurèe ne doit pas dépasser 0.75V (corre-

spondante 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.

PRECAUTION: POUR LA PROTECTION CON-

TINUE CONTRE LES RISQUES D'INCENDIE,

REMPLACER LE FUSIBLE

VERIFICATIONS CONTRE L'INCEN-DIE ET LE

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:

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.

Lead-free wire solder for servicing

Indicates lead-free solder of tin, silver and copper. Indicates lead-free solder of tin, silver and copper.

[Precautions for assembly]

(Front Cabinet Ass’y/Rear Cabinet Ass’y fingernail fixation place)

Push

CAUTION

Set it so that there may not be a clearance between Front Cabinet Ass'y and Rear Cabinet Ass'y.

There is a gap without the fingernail fitting

in completely only when covering with Rear Cabinet Ass'y.

The fingernail is surely fixed when Rear cabinet Ass'y is

firmly pushed, and the gap disappears.
