Service Manual
This IC is 512MB NAND flash memory.
This IC stores the software data that processes the system of TV such
as the graphic processing, the LCD controls, and backlights etc.
This IC is Video Processor & MAIN CPU.
In this IC, the decode processing and the video signal processing are
done. Moreover, OSD is generated here and added to a picture signal.
The monitor microprocessor is intended to communicate with the main
CPU and to operate the system.
It also controls power of the entire system.
This IC is 1GB DDR2 SDRAM.
This IC operates as a memory of IC3302 (Video Processor). ***
This IC is a 1Kbit-2-wire (I2C bus type) serial EEPROM that can be
programmed electrically. The EEPROM chip stores the EDID data of
PC input. This data is controlled through I2C signals.
The BR24S64W is a 64Kbit-2-wire (I2C bus type) serial EEPROM that
can be programmed electrically. This IC stores the menu data and the
adjustment value data of adjustment process mode etc. The data is
given out by commands from the main microprocessor.
The MAX3221E is a single driver, single receiver RS-232 solution
operating from a single Vcc supply. The RS-232 pins provide IEC
G1000-4-2 ESD Protection. The device meets the requirements of
TIA/EIA-232-F and provides the electrical interface between an asyn-
chronous communication controler and the serial-port connector. The
charge pump and four small external capacitors allow operation from a
single 3V to 5.5V supply.
This is a control IC for PCMCIA cards. This controls information on IC
cards inserted into the PCMCIA card slot (SC4401) or information on
software version upgrade cards saved on flash memories to transfer
the data to CPUs and memories.
This is a 2Kbit-2-wire (I2C bus type) serial EEPROM that can be pro-
grammed electrically. This IC stores the menu data and the adjust-
ment value data of adjustment process mode etc. The data is given
out by commands from the main microprocessor.
The SiI9287 HDMI port processor is the second generation of HDMI
devices that support revision 1.3 of the HDMI specification. The main
feature is as follows.
1) 4-input, 1-output HDMI port processor.
2) Integrated TMDS receiver and transmitter cores capable of receiv-
ing and transmitting at 2.25Gbps.
3) Supports video resolutions up to 1080p, 60Hz, 12bit or 720p/1080i,
120Hz,12bit.
4) Receiver fully comply with DVI1.0, HDCP1.1 and HDMI1.3 specifi-
cations.
The STV0297E's demodulator is a complete QAM (quadrature ampli-
tude modulation) demodulation and FEC (forward error correction)
solution that performs IF to transport stream block processing of QAM
signals. It is intended for the digital transmission of compressed televi-
sion, sound, and data services over cable.
This IC is a single supply 10Base-T/100Base-TX Physical Layer
Transceiver, which provides MII/RMII/SMII interfaces to transmit and
receive data.
This IC is the Sound processing LSI with built-in two DSP (MDSP/
SDSP) and FM (frequency modulation) oscillators. This IC process
sound signal and sent it to AMP for Speaker and Woofer
This IC is digital audio power amplifier with digital audio interface.
The power-supply voltage is corresponded to A.8V~18V and the max-
imum output is 20Wx2ch.
It is IC for amplifying the feeble electric wave sent from satellite broad-
casting on the level which can treat a decoder, and changing and pro-
cessing signal.
