CONTENTS

In the interests of user-safety (Required by safety regulations in some countries) the set should be restored to its orig-inal condition and only parts identical to those specified should be used.

This Service Manual covers the differences from LC-32D44U. For other technical information, refer to the LC-32D44U(No. SY7C1LC32D44U) Service Manual.

LC32SB24U Service ManualSAFETY PRECAUTION

IMPORTANT SERVICE SAFETY PRECAUTION

WARNING1. 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 followingsafety checks:

3. Inspect all lead dress to make certain that leads are not pinched,and check that hardware is not lodged between the chassis andother metal parts in the receiver.

4. Inspect all protective devices such as non-metallic control knobs,insulation materials, cabinet backs, adjustment and compartmentcovers or shields, isolation resistor-capacitor networks, mechanicalinsulators, 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 0.15 F capacitor in series with all exposed metal cabinetparts 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 areturn to the chassis (antenna, metal cabinet, screw heads, knobsand control shafts, escutcheon, etc.) and measure the AC voltagedrop across the resistor.

All checks must be repeated with the AC cord plug connectionreversed. (If necessary, a nonpolarized adaptor plug must be usedonly 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 whichmust be corrected before returning the monitor to the owner.

SAFETY NOTICEMany electrical and mechanical parts in LCD color television havespecial safety-related characteristics.

These characteristics are often not evident from visual inspection, nor can protection afforded by them be necessarily increased by usingreplacement components rated for higher voltage, wattage, etc.

Replacement parts which have these special safety characteristics areidentified in this manual; electrical components having such features

are identified by " " and shaded areas in the Replacement Parts Listand Schematic Diagrams.

For continued protection, replacement parts must be identical to thoseused in the original circuit.

The use of a substitute replacement parts which do not have the samesafety characteristics as the factory recommended replacement partsshown 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 theservicing guidelines which follow:

C A U T I O N : FOR CONTINUED PROTECTION AGAINST A RISK OF FIRE REPLACE ONLY WITHSAME TYPE FUSE.

PRECAUTIONS A PRENDRE LORS DE LA REPARATION

De nombreuses pices, lectriques et mcaniques, dans les tlvi-seur ACL prsentent des caractristiques spciales relatives la s-curit, qui ne sont souvent pas videntes vue. Le degr de protec-tion ne peut pas tre ncessairement augmente en utilisant despices de remplacement talonnes pour haute tension, puissance,etc.Les pices de remplacement qui prsentent ces caractristiques sontidentifies dans ce manuel; les pices lectriques qui prsentent cesparticularits sont identifies par la marque " " et hachures dans laliste des pices de remplacement et les diagrammes schmatiques.

Pour assurer la protection, ces pices doivent tre identiques cellesutilises dans le circuit d'origine. L'utilisation de pices qui n'ont pasles mmes caractristiques que les pices recommandes par l'usine,indiques dans ce manuel, peut provoquer des lectrocutions, incen-dies, radiations X ou autres accidents.

Ne peut effectuer la rparation qu' un technicien spcialis qui s'est parfaitement accoutum toute vrification de scurit et auxconseils suivants.

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

Dbrancher le rcepteur avant toute rparation.

Inspecter tous les faisceaux de cbles pour s'assurer que les filsne soient pas pincs ou qu'un outil ne soit pas plac entre le chs-sis et les autres pices mtalliques du rcepteur.

Inspecter tous les dispositifs de protection comme les boutons decommande non-mtalliques, les isolants, le dos du coffret, les cou-vercles ou blindages de rglage et de compartiment, les rseauxde rsistancecapacit, les isolateurs mcaniques, etc.

S'assurer qu'il n'y ait pas de danger d'lectrocution en vrifiant lafuite 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 l'aide de deux fils pinces, brancher une rsistance de 1.5 k 10 watts en parallle avec un condensateur de 0.15 F en srieavec toutes les pices mtalliques exposes du coffret et une terreconnue comme une conduite lectrique ou une prise de terrebranche la terre.

Utiliser un voltmtre CA d'une sensibilit d'au moins 5000 /V pour mesurer la chute de tension en travers de la rsistance.

Toucher avec la sonde d'essai les pices mtalliques exposes quiprsentent une voie de retour au chssis (antenne, coffret mtalli-que, tte des vis, arbres de commande et des boutons, cusson,etc.) et mesurer la chute de tension CA en-travers de la rsistance.Toutes les vrifications doivent tre refaites aprs avoir invers lafiche du cordon d'alimentation. (Si ncessaire, une prised'adpatation non polarise peut tre utilise dans le but de termin-er ces vrifications.)La tension de pointe mesure ne doit pas dpasser 0.75V (corre-spondante au courant CA de pointe de 0.5mA).Dans le cas contraire, il y a une possibilit de choc lectrique quidoit tre supprime avant de rendre le rcepteur au client.
