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:
WARNING
1. For continued safety, no modification 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 FUSE.
42" F901 (T6.3AH/250V)
26"/32" F901 (T5AH/250V)
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.
• 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 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 1.05 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.

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. When a lamp in LCD panel is broken and the protector circuit in inverter operates and we tune on the this set, LED keep red? or Green?
2. Service man only change the lamp in LCD panel?
1. If the lamp(s) is(are) broken, panel inverter will not kick on the lamps, so TV set phenomena will be "no picture on display." But the TV system is still working, that is the RC can also control LED. When AC power on, the LED will keep last status and when use RC DC power on, the LED will keep green light.
2. The failed panel should be sent back to Panel maker (CMO) via RMA process. Panel maker (CMO) will not rework the lamps at customer's side since the repaired panel should be checked through regular inspection flow to secure the quality.
Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, office), 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: +5°C to +35°C.

1.2. U101 (Si2163 QFN-36)
Description
The analog front-end consists of two ADCs with wide dynamic range (12-bit) to allow operation with standard IF (~36 MHz), Low-IF, or Zero-IF
inputs. This enables the use of the Si2163 with any TV tuner, either metal can or silicon tuner based. The Si2163 supports ITU J.83 annex A/C and
DVB-C (EN 300 429) and accepts symbol rates from 1 to 7 MSymbol/s.The Si2163 includes a user-configurable 31-tap equalizer for optimum
reception even in case of difficult network conditions, such as long echoes. Serial or parallel master MPEG TS output modes are supported.
Furthermore, a TS slave parallel mode is available via a GPIF port and provides glue less interface to Silicon Labs' MCU devices with embedded
USB interface. The user can optionally program a 32-PID hardware filter to reduce the output TS bit rate (or add more TS security for Pay-TV
channels).An embedded DSP controls the scanning operations. The Si2163 supports ultra-fast channel scanning for VHF/UHF cable DTV channels,
thanks to proprietary features. For supported tuners, the complete algorithm for fast channel scan, QuickScan, is provided as a downloadable patch
file. QuickScan runs on the embedded DSP to limit the host CPU / MPEG decoder software burden.An internal I
2
C pass-through logic switch acts
as an I
2
C repeater and provides a "quiet" I2C bus to the RF front end. A maximum of six general-purpose inputs/outputs are available; three GPIOs
also feature Δ/Σ and interrupt output capabilities. Best-in-class demodulation performance is achieved while still maintaining very low-power
operation. The Si2163 also includes an IF sub-sampling mode for further reducing power consumption. The Si2163 guarantees a low-cost system
implementation due to its minimal BOM and very small package footprint. Si2163 remains pin-to-pin application compatible with Si2165 (multi-
standard DVB-T & DVB-C demodulator) and Si2161 (DVB-T demodulator).
Features

selectable at –6 dB, 0 dB, 3 dB or 6 dB. The amplifier drives 25 mW into 16 speakers from a single 2.3 V supply. The TPA6132A2 (TPA6132)
provides a constant maximum output power independent of the supply voltage, thus facilitating the design for prevention of acoustic shock.
The TPA6132A2 (TPA6132) features fully differential inputs to reduce system noise pickup between the audio source and the headphone amplifier.
The high power supply noise rejection performance and differential architecture provides increased RF noise immunity. For single-ended input
signals, connect
INL+ and INR+ to ground.
The device has built-in pop suppression circuitry to completely eliminate disturbing pop noise during turn-on and turn-off. The amplifier outputs have
short-circuit and thermal-overload protection along with ±8 kV HBM ESD protection, simplifying end equipment compliance to the IEC 61000-4-2
ESD standard.
The TPA6132A2 (TPA6132) operates from a single 2.3 V to 5.5 V supply with 2.1 mA of typical supply current. Shutdown mode reduces supply
current to
less than 1 mA.

SUMMARY DESCRIPTION
The HYNIX HY27US(08/16)281A series is a 16Mx8bit with spare 4G bit capacity. The device is offered in 1.8V Vcc Power Supply and in 3.3V Vcc
Power Supply.
Its NAND cell provides the most cost-effective solution for the solid state mass storage market.
The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased.
The device contains 1024 blocks, composed by 32 pages consisting in two NAND structures of 16 series connected Flash cells.
A program operation allows to write the 512-byte page in typical 200us and an erase operation can be performed in typical 2ms on a 16K-byte(X8
device) block.
Data in the page mode can be read out at 50ns cycle time per byte. The I/O pins serve as the ports for address and data input/output as well as
command input. This interface allows a reduced pin count and easy migration towards different densities, without any rearrangement of footprint.
Commands, Data and Addresses are synchronously introduced using CE#, WE#, ALE and CLE input pin. The on-chip Program/Erase Controller
automates all program and erase functions including pulse repetition, where required, and internal verification and margining of data.
The modifying can be locked using the WP# input pin.
The output pin RB# (open drain buffer) signals the status of the device during each operation. In a system with multiple memories the RB# pins can
be connected all together to provide a global status signal.
Even the write-intensive systems can take advantage of the HY27US(08/16)281A extended reliability of 100K program/
erase cycles by providing ECC (Error Correcting Code) with real time mapping-out algorithm.
Optionally the chip could be offered with the CE# don’t care function. This option allows the direct download of the code from the NAND Flash
memory device by a microcontroller, since the CE# transitions do not stop the read operation.
The copy back function allows the optimization of defective blocks management: when a page program operation fails the data can be directly
programmed in another page inside the same array section without the time consuming serial data insertion phase.
This device includes also extra features like OTP/Unique ID area, Block Lock mechanism, Automatic Read at Power Up, Read ID2 extension.
The Hynix HY27US(08/16)281A series is available in 48 - TSOP1 12 x 20 mm, 48 - USOP1 12 x 17 mm.

A proprietary low-dropout transmitter output stage delivers true RS-232 performance from a +3.0V to +5.5V power supply, using an internal dual
charge pump. The charge pump requires only four small 0.1µF capacitors for operation from a +3.3V supply. Each device guarantees operation at
data rates of 250kbps while maintaining RS-232 output levels. The MAX3237E guarantees operation at 250kbps in the normal operating mode and
1Mbps in the MegaBaud™ operating mode, while maintaining RS-232 compliant output levels.
The MAX3222E/MAX3232E have two receivers and two transmitters. The MAX3222E features a 1µA shutdown mode that reduces power
consumption in battery-powered portable systems. The MAX3222E receivers remain active in shutdown mode, allowing monitoring of external
devices while consuming only 1µA of supply current. The MAX3222E and MAX3232E are pin, package, and functionally compatible with the
industry-standard MAX242 and MAX232, respectively.
The MAX3241E/MAX3246E are complete serial ports (three drivers/five receivers) designed for notebook and subnotebook computers. The
MAX3237E (five drivers/three receivers) is ideal for peripheral applications that require fast data transfer. These devices feature a shutdown mode
in which all receivers remain active, while consuming only 1µA (MAX3241E/MAX3246E) or 10nA (MAX3237E).
The MAX3222E, MAX3232E, and MAX3241E are available in space-saving SO, SSOP, TQFN and TSSOP packages. The MAX3237E is offered in
an SSOP package. The MAX3246E is offered in the ultra-small 6 x 6 UCSP™ package.
