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.

=VERIFICATIONS CONTRE L'INCEN=DIE ET LE

CHOC ELECTRIQUE

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 dolt _tre supprim6e avant de rendre le r6cepteur au client.

AVIS POUR LA SECURITE

De nombreuses pi6ces, electriques et m6caniques, dans les t616vi- seur ACL pr6sentent des caract@istiques sp6ciales relatives _ la s6-

curit6, qui ne sont souvent pas 6videntes _ vue. Le degr6 de protec- tion ne peut pas 6tre n6cessairement augment6e en utilisant des pi6ces de remplacement 6talonn6es pour haute tension, puissance, etc.

Les pi_ces de remplacement qui pr6sentent ces caract@istiques sont identifi6es dans ce manuel; les pi_ces 61ectriques qui presentent ces particularit6s sont identifiees par la marque "Z_" et hachur_es dans la

liste des pi_ces de remplacement et les diagrammes sch_matiques.

Pour assurer la protection, ces pi_ces doivent @re identiques _ celles utilis_es dans le circuit d'origine. L'utilisation de pi_ces qui n'ont pas

les m_mes caract@istiques que les pi_ces recommand_es par I'usine, indiqu_es dans ce manuel, peut provoquer des _lectrocutions, incen-

dies, radiations X ou autres accidents.

LC-52LE920UN/LC-60LE920UN 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.

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.
