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.

CAUTIO N : FOR CON TINUED PROTECTION AGAINST A RISK OF FIRE REPLACE ONLY WITH SAME TYPE F7502 (2.5A, 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

•

Using two clip leads, connect a 1.5k ohm, 10 watt

•

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).

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.

checks must be repeated with the AC cord plug

All

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 Replacement Parts Lists and Schematic Diagrams. For continued protection, replacement parts must be identical to those used in the original circuit. The use of 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.

PRECAUTIONS A PRENDRE LORS DE LA REPARATION

La réparation ne peut être effectuée que par un technicien spécialisé qui s'est parfaitement accoutumé à toute vériﬁcation de sécurité et aux conseils suivants.

AVERTISSEMENT

1. Pour la sécurité continue, n'entreprendre aucune modiﬁcation de tout circuit.

2. Débrancher l'alimentation CA avant la réparation.

PRECAUTION: POUR LA PROTECTION CONTINUE CONTRE LES RISQUES D'INCENDIE, REMPLACER LE FUSIBLE PAR UN FUSIBLE DE MEME TYPE F7502 (2.5A, 250V).

AVANT DE RENDRE LE RECEPTEUR A L’UTILISATEUR (Incendie et choc électrique)

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

•

5000Ω/V pour mesurer la chute de tension CA 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 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 doit être utilisée dans le but de terminer ces vériﬁcations.)

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.

AVIS POUR LA SECURITE

De nombreuses pièces, électriques et mécaniques, dans les téléviseurs de l'afficharge à cristaux liquides présentent des caractéristiques spéciales relatives à la sécurité. Ces caracténstiques 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. 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 ou autres accidents.

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:

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.

PUBLIC MODE SETTING PROCEDURE

1. How to start Public Mode

There are the following two ways to get the public mode setup screen displayed.

•

In the adjustment process mode, turn on "HOTEL MODE". Also press the "CH (r)" and "VOL (+)" keys

on the set at once and turn on the power.

1) Press the "INPUT" and "V

2) Get the password input screen displayed.

OL (+)" keys on the set at once and turn on the power.

Procedure

The input starts with the leftmost digit.

•

Use the numeric keys [1] thru [9] and [0] keys on the remote con-

•

troller. The other keys are not acceptable.

With a numeric-key input, "–" will change to "✽". The input position

•

will move one digit to the right.

With all the 3 digits entered, the password will be veriﬁed.

•
