SAFETY PRECAUTION
IMPORTANT SERVICE SAFETY PRECAUTION
Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the servicing guidelines which follow: · Use an AC voltmeter having with 5000 ohm per volt, or higher, sen-
WARNING
1. For continued safety, no modification of any circuit should be attempted. 2. Disconnect AC power before servicing.
sitivity or measure the AC voltage drop across the resistor. · Connect the resistor connection to all exposed metal parts having a return to the chassis (antenna, metal cabinet, screw heads, knobs and control shafts, escutcheon, etc.) and measure the AC voltage drop across the resistor.
CAUTION: FOR CONTINUED PROTECTION AGAINST A RISK OF FIRE REPLACE ONLY WITH SAME TYPE FUSE. 42" F901 (T6.3AH/250V) 26"/32" F901 (T5AH/250V)
All checks must be repeated with the AC cord plug connection reversed. (If necessary, a nonpolarized adaptor plug must be used only 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 which must be corrected before returning the monitor to the owner.
BEFORE RETURNING THE RECEIVER
(Fire & Shock Hazard)
Before returning the receiver to the user, perform the following safety checks: 3. Inspect all lead dress to make certain that leads are not pinched, and check that hardware is not lodged between the chassis and other metal parts in the receiver. 4. Inspect all protective devices such as non-metallic control knobs, insulation materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacitor networks, mechanical insulators, 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 220~240 volt AC outlet. · Using two clip leads, connect a 1.5k ohm, 10 watt resistor paralleled by a 0.15µF capacitor in series with all exposed metal cabinet parts and a known earth ground, such as electrical conduit or electrical ground connected to an earth ground. ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// TO EXPOSED METAL PARTS CONNECT TO KNOWN EARTH GROUND 0.15 µF TEST PROBE DVM AC SCALE 1.5k ohm 10W
SAFETY NOTICE
Many electrical and mechanical parts in LCD color television have special safety-related characteristics. These characteristics are often not evident from visual inspection, nor can protection afforded by them be necessarily increased by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this manual; electrical components having such features are identified by " " and shaded areas in the Replacement Parts List and Schematic Diagrams. ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// For continued protection, replacement parts must be identical to those used in the original circuit. The use of a substitute replacement parts which do not have the same safety characteristics as the factory recommended replacement parts shown in this service manual, may create shock, fire or other hazards.

Precautions for using lead-free solder
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 damage 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 soldering bit, 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 be peeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady 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 as required. 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.

1.4. U600 (TDA8933BTW HTSSOP32)
General description The TDA8933B is a high-efficiency class D amplifier with low power dissipation. The continuous-time output power is 2 × 10 W in a stereo half-bridge application (RL = 8 ) or 1 × 20 W in a mono full-bridge application (RL =16 ). Due to the low power dissipation the device can be used without any external heat sink when playing music. Due to the implementation of thermal foldback(TF) the device remains operating with considerable music output power without the need for an external heat sink, even for high supply voltages and/or lower load impedances.
The device has two full differential inputs driving two independent outputs. It can be used in a mono full-bridge configuration (Bridge-Tied Load(BTL)) or as stereo half-bridge configuration (Single-Ended(SE)).
