SAFETY 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 inthe following manner.

• Plug the AC cord directly into a 110-240 volt 50/60Hz 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 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.) ormore is excessive and indicates a potential shock hazard whichmust be corrected before returning the monitor to the owner.

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 despièces de remplacement étalonnées pour haute tension, puissance,etc.Les pièces de remplacement qui présentent ces caractéristiques sontidentifiées dans ce manuel; les pièces électriques qui présentent cesparticularités sont identifiées par la marque " " et hachurées dans laliste des pièces de remplacement et les diagrammes schématiques.

Pour assurer la protection, ces pièces doivent être identiques à cellesutilisées dans le circuit d'origine. L'utilisation de pièces qui n'ont pasles mêmes caractéristiques que les pièces recommandées par l'usine,indiquées dans ce manuel, peut provoquer des électrocutions, incen-dies, radiations X ou autres accidents.

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 filsne 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 decommande non-métalliques, les isolants, le dos du coffret, les cou-vercles ou blindages de réglage et de compartiment, les réseauxde résistancecapacité, les isolateurs mécaniques, etc.

S'assurer qu'il n'y ait pas de danger d'électrocution en vérifiant lafuite de courant, de la facon suivante:

Brancher le cordon d'alimentation directem-ent à une prise de cou-rant de 110-240V 50/60Hz. (Ne pas utiliser de transformateurd'isolation pour cet essai).

A l'aide de deux fils à pinces, brancher une résistance de 1.5 kΩ10 watts en parallèle avec un condensateur de 0.15µF en sérieavec toutes les pièces métalliques exposées du coffret et une terreconnue comme une conduite électrique ou une prise de terrebranchée à la terre.

Utiliser un voltmètre CA d'une sensibilité d'au moins 5000Ω/V pourmesurer la chute de tension en travers de la résistance.

Toucher avec la sonde d'essai les pièces métalliques exposées quiprésentent 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 lafiche du cordon d'alimentation. (Si nécessaire, une prised'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 quidoit être supprimée avant de rendre le récepteur au client.

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 solderingbit, 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 bepeeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm thesteady 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 asrequired.

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.

Troubleshooting

Possible Solution

Is the volume too low?Is "Variable" selected in "Output Select"?Have you pressed MUTE on the remote control unit?

Cautions regarding use in high and low temperature environments

Problem

No power

Unit cannot be operated.

Remote control unit does notoperate.

Picture is cut off/with sidebarscreen.

Strange color, light color, or colormisalignment

Power is suddenly turned off.

No picture

No sound

Check if you pressed TV POWER on the remote control unit.If the indicator on the TV does not light up, press POWER on the TV.Is the AC cord disconnected?Has the power been turned on?

External influences such as lightning, static electricity, may cause improper operation.In this case, operate the unit after first turning off the power of the TV or unpluggingthe AC cord and replugging it in after 1 or 2 minutes.

Is the FUNCTION set correctly? Set it to the TV setting position.Are batteries inserted with polarity ( , ) aligned?Are batteries worn out? (Replace with new batteries.)Are you using it under strong or fluorescent lighting?Is a fluorescent light illuminated near the remote control sensor?

Is the image position correct?Are screen mode adjustments such as picture size made correctly?

Adjust the picture tone.Is the room too bright? The picture may look dark in a room that is too bright.Check the input signal setting.

Is the sleep timer set?Check the power control settings.The unit's internal temperature has increased. Remove any objects blocking vent orclean.

Is connection to other components correct?Is correct input signal source selected after connection?Is the correct input selected?Is picture adjustment correct?Is "On" selected in "Audio Only"?Is a non-compatible signal being input?

When the unit is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly delayed.This is not a malfunction, and the unit will recover when the temperature returns to normal.Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near aheater, as this may cause the cabinet to deform and the Liquid Crystal panel to malfunction.Storage temperature: 4°F to 140°F ( 20°C to 60°C)

Troubleshooting-Digital Broadcasting

The error message about reception of broadcast

Failed to receive broadcast.

E203 Check the broadcast time in the program guide.

The example of an error messagedisplayed on a screen

No broadcast now.

Error code

E202

Possible Solution

Check the antenna cable. Check that the antenna is correctlysetup.

This is not a malfunction. This happens when the cabinet slightly expands andcontracts according to change in temperature. This does not affect the TV'sperformance.

The TV sometimes makes acracking sound.
