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-19D1E/S-BK/WH. For other technical information, refer to the LC-19D1E/S-BK/WH (No. S58J9LC19D1ES) Service Manual.

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 220~240 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 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 1.05 V peak (this corresponds to 0.7 mA peak 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, norcan 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 featuresare identified by “ ” and shaded areas in the Replacement PartsList and 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 the servicing guidelines which follow:

CAUTION:

FOR CONTINUED PROTECTION AGAINST A

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.
