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 0.15F 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.

LC-32A47E/RU/VPrecautions 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.

The TV cannot be operated. External influences such as lightning, static electricity, etc., may cause improper operation. Inthis case, operate the TV after first turning off the power, or unplugging the AC cord and re-plugging it in after one or two minutes.

Remote control unit does notoperate.

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 to the remote control sensor?

Picture is cut off. Is the image position correct?Are screen mode adjustments (4:3 Mode/WSS) such as picture size made correctly?

Strange colour, light colour,or dark colour, or colourmisalignment.

Adjust the picture tone.Is the room too bright? The picture may look dark in a room that is too bright.Check the colour system setting.Check the HDMI Setup setting.

Power is suddenly turned off. The TVs internal temperature has increased.Remove any objects blocking the vent or clean.Check the power control setting.Is sleep timer set? Press SLEEP on the remote control unit until it sets to Off.

No picture. Are connections to other components correct?Is the input signal type selected correctly after connection?Is the correct input source selected?Is a non-compatible signal being input?Is the picture adjustment correct?Is the antenna connected properly?Is On selected in Audio Only?

No sound. Is the volume too low?Check if you pressed on the remote control unit.Check the setting in Audio Select in the HDMI Setup menu. When using an HDMI-DVIconversion adapter/cable, select Analogue. If you want to receive an audio signal from a PCselect Digital.

The TV sometimes makes acracking sound.

This is not a malfunction. This happens when the cabinet slightly expands and contractsaccording to change in temperature. This does not affect the TVs performance.

Cautions regarding use in high and low temperature environmentsWhen the unit is used in a low temperature space (e.g., room, office), the picture may leave trails or appearslightly 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 sunlightor near a heater, as this may cause the cabinet to deform and the LCD panel to malfunction.Storage temperature: -20C to +60C.

IMPORTANT NOTE ON RESETTING THE PINWe suggest that you remove the following instruction from the operation manual to prevent children from reading it.As this operation manual is multilingual, we also suggest the same with each language. Keep it in a safe space forfuture reference.
