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 currentin the following manner. Plug the AC cord directly into a 110-240 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 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.///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////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 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 the servicing guidelines which follow: CAUTI ON: FOR CONTI NUED PROTECTIONAGAINST A RISK OF FIRE REPLACE ONLY WITHSAME TYPE FUSE.F7000 (250V 5A)DVMAC SCALE1.5k ohm10WTO EXPOSEDMETAL PARTSCONNECT TOKNOWN EARTHGROUND0.15 FTEST PROBELC-42D65UiiPRECAUTIONS A PRENDRE LORS DE LA REPARATIONDe 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.

The LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals. Thealphabetical 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 poorsolder 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 servicingIndicates lead-free solder of tin, silver and copper.
