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
F700, F701 (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.
LF 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.

channel) efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers. Advanced EMI
Suppression Technology enables the use of inexpensive ferrite bead filters at the outputs while meeting
EMC requirements. SpeakerGuard™ speaker protection circuitry includes an adjustable power limiter and
a DC detection circuit. The adjustable power limiter allows the user to set a "virtual" voltage rail lower
than the chip supply to limit the amount of current through the speaker. The DC detect circuit measures
the frequency and amplitude of the PWM signal and shuts off the output stage if the input capacitors are
damaged or shorts exist on the inputs.
The TPA3113D2 can drive stereo speakers as low as 4

unit. MB60 chassis can operate with IPS60, IPS16, IPS17, PW26, PW27 as main power supply and also with
12V adaptor.
CN706 is used for IPS60, IPS16 and IPS17 and CN1 is used for PW26 and PW27.
JK9 is used for the adapter option and also CN705 inverter socket or DB32 chassis with CN706 is used to
supply backlight.
The power supplies generate 18V, 12V, 5V, 3,3V and 12V, 5V, standby mode DC voltages. Power stage
which is on-chassis generates 5V, 3V3 stand by voltage and 12V, 8V, 5V, 3V3, 2.5V, 1,8V and 1,2V supplies
for other different parts of the chassis. Chassis block diagram is indicated below.
Short circuit protection is necessary for protecting chassis and main IC against damages when any Vcc
supply shorts to ground. Protect pin should be logic high while normal operation. When there is a short
circuit protect pin should be logic low. After any short detection, SW forces LEDs on LED card to blink.

MX25L1005 is a CMOS 1,048,576 bit serial Flash memory, which is configured as 131,072 x 8 internally.
The MX25L1005 feature a serial peripheral interface and software protocol allowing operation on a simple
3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output
(SO). SPI access to the device is enabled by CS# input. The MX25L1005 provide sequential read operation
on whole chip. After program/erase command is issued, auto program/ erase algorithms which program/
erase and verify the specified page or sector/block locations will be executed. Program command is
executed on page (256 bytes) basis, and erase command is executes on chip or sector(4K-bytes) or
block(64K-bytes). To provide user with ease of interface, a status register is included to indicate the status
of the chip. The status read command can be issued to detect completion status of a program or erase
operation via WIP bit. When the device is not in operation and CS# is high, it is put in standby mode and
draws less than 10uA DC current. The MX25L1005 utilize MXIC's proprietary memory cell, which reliably
stores memory contents even after 100,000 program and erase cycles.

15.NAND FLASH MEMORY – NAND512XXA2C (U162)
15.1.General Description
14.1
The NAND flash 528-byte/ 264-word page is a family of non-volatile flash memories that uses the single
level cell (SLC) NAND technology. It is referred to as the small page family.
The NAND512R3A2C, NAND512R4A2C, and NAND512W3A2C have a density of 512 Mbits and operate with
either a 1.8 V or 3 V voltage supply. The size of a page is either 528 bytes (512 + 16 spare) or 264 words
(256 + 8 spare) depending on whether the device has a x8 or x16 bus width.
The address lines are multiplexed with the Data Input/output signals on a multiplexed x8 or x16
input/output bus. This interface reduces the pin count and makes it possible to migrate to other densities
without changing the footprint.
To extend the lifetime of NAND flash devices it is strongly recommended to implement an error
correction code (ECC). The use of ECC correction allows to achieve up to 100,000 program/erase cycles
for each block. A write protect pin is available to give a hardware protection against program and erase
operations.
