IMPORTANT SERVICE SAFETY PRECAUTION
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
F9901, F9902 (T 5A/250V)
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.
• 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 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.
2 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.

compliance with JEDEC standard no. 7A. The 74HC4052 is a dual 4-channel analog multiplexer/demultiplexer with common
select logic. Each multiplexer has four independent inputs/outputs (pins nY0 to nY3) and a common input/output (pin nZ). The
common channel select logics include two digital select inputs (pins S0 and S1) and an active LOW enable input (pin E). When
pin E = LOW, one of the four switches is selected (low-impedance ON-state) with pins S0 and S1. When pin E = HIGH, all
switches are in the high-impedance OFF-state, independent of pins S0 and S1. VCC and GND are the supply voltage pins for
the digital control inputs (pins S0, S1 and E). The VCC to GND ranges are 2.0 V to 10.0 V for the 74HC4052.The analog
inputs/outputs (pins nY0 to nY3 and nZ) can swing between VCC as a positive limit and VEE as a negative limit. VCC − VEE
may not exceed 10.0 V. For operation as a digital multiplexer/demultiplexer, VEE is connected to GND (typically ground).

General Description
The SSC9522S is a controller IC (SMZ method) for half-bridge resonant type power supply, incorporating a floating drive circuit
for High-side MOSFET drive.
※SMZ = Soft-switched Multi-resonant Zero Current switch.
All switching periods work with soft switching operation.
The IC is in SOP18 package, and suitable for high performance power supply system with small size, high efficiency and low
noise, because for various power supply specifications, more effective and easier design works are achievable with effective
functions as the Automatic Dead Time Adjustment, the Uncontrollable Operation Detection and so on.
※Uncontrollable Operation Detection = there are two areas in resonant circuit impedance; capacitance area and inductance
area. The Uncontrollable Operation occurs in capacitance area (the frequency is lower than the resonant frequency, fO), the
output voltage can not be controlled and the switching operation becomes hard switching.
Features
• SOP18 package
• Built-in floating drive circuit for High-side MOSFET
• Soft Start Function, reducing of power MOSFET stress and preventing Uncontrollable Operation, at startup
• Uncontrollable Operation Detection Function on pulse-by-pulse basis, improving the ability of transformer output wattage
because the frequency range is available up to the resonant frequency, fO, and reducing power MOSFET stress
• Automatic Dead Time Adjustment Function, not being necessary to make the dead time adjustment for each power supply
specification
• Protection Functions
- Line Undervoltage Protection Function-(Brown-In／Brown-Out Function)------------------Prevention of excessive input current
and overheat at low input voltage
