ELECTRICAL SPECIFICATIONS
Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, offi ce), 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 a heater, as this may
cause the cabinet to deform and the LCD panel to malfunction. Storage
temperature: –20°C to +60°C
.
Specifications
• As a part of our policy of continuous improvement, SHARP reserves the right to
make design and specifi cation changes
for product improvement without prior
notice. The performance specifi cation fi gures indicated are nominal values of production units. There may be some deviations from these values in individual unit

Service work should be performed only by qualied service technicians who are thoroughly familiar with all
safety checks and the servicing guidelines which follow:
WARNING
1. For continued safety, no modication of any circuit should be attempted.
2. Disconnect AC power before servicing.
CAUTION: FOR CONTINUED PROTECTION AGAINST A RISK OF
FIRE REPLACE ONLY WITH SAME TYPE
F800, F801 (T 3.15A L250V)
BEFORE RETURNING THE RECEIVER (Fire & Shock Hazard)
Before returning the receiver to the user, perform the following safety checks:
1. 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.
2. 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.
3. To be sure that no shock hazard exists, check for leakage current in the following manner.
IMPORTANT SERVICE SAFETY PRECAUTION
• Plug the AC cord directly into a 220~240 volt AC outlet. (Do not use an isolation transformer for this test).
•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.
•A true RMS reading multimeter should be used for this test, especially where the equipment uses a switch mode
power supply which may result in very non-sinusoidal leakage current.
•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.
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 1.05V 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.

SAFETY NOTICE
Many electrical and mechanical parts in LCD 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 identied in this manual; electrical components
having such features are identied by “ “.
!
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, re or other hazards.

PRECAUTIONS FOR USING LEAD-FREE SOLDER
1 Employing lead-free solder
“ALL PWB” 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:
Indicates lead-free solder of tin, silver and copper.
L F n
Sn-Ag-Ni
2 Using lead-free wire solder
When xing 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.
3 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 conrm 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, le it with steel wool or ne 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 nickel.

5. AUDIO AMPLIFIER STAGE WITH AZAD2102(U163, U164)
5.1.General Description
17MB60 uses two 2,5W Class D Mono Audio Amplifers for from 16” to 24” TVs. AZAD2102B is a 2.9 Watts
(max. can offer 3.0 Watts @ Load = 3Ω,THD=10%, AVdd=DVdd=5.5Volt)with high efficiency filter-free
class-D audio power amplifier in a 1613 mm x 1613 mm wafer chip scale package (WCSP). AZAD2102B uses
Current-switch technology to achieve high performance class-d amplifier that features 0.03% THD, 85%
efficiency, –70 dB PSRR, to improve RF-rectification immunity. AZAD2102B provide a Vibration-Spectrum
modulation clock for PWM Output. This vibration frequency is around 10KHZ shift (+/- 5KHZ of Fpwm).
The advantage of the small size package (WCSP) makes AZAD2102B very suitable for mobile phone and
PDA device application. And the Class-D amplifier structure let AZAD2102B to have highly efficiency
power consumption than Class-AB amplifier. AZAD2102B can shrink the application board, reduce system
cost, and external components.
ESD level protection I/O embedded in AZAD2102B. For general applications, doesn’t need to add extra
ESD protection device (like Varistors) in application system for AZAD2102B’s I/O.
