1. IF PWB
1. IC6001 (VHiS24CS02J-1Y)
This is an EEPROM in which the EDID for the HDMI of the display is stored. The writing process is carried out by executing the EDID WRITE func-
tion described on page 3. The writing process must be implemented when the IC is replaced. The harness of the LB connector (P7908) on the IF
PWB is also used for identifying the size of the monitor. The harness of the KM connector (P7905) on the IF PWB is also used for setting the des-
tination of the monitor. The writing process must be carried out after the proper harnesses are attached. (The EDID varies depending on the types
of harnesses.)
While the STB reads the value contained in this EEPROM, the model mode on the side of the STB changes accordingly (as indicated on the upper
right side of the page 1 of the process screen for STB). Also, the operation of the monitor alone mode partially changes depending on the destina-
tion.
2. IC6004 (VHiSII9181A-1Q)
This is an HDMI SW used as an equalizer for waveform shaping in case any cable other than the attached HDMI cable is used or the optional 10
m cable (planned) is used.

Part Code
This IC is FPGA (Field Programmable Gate Array) IC.
In this IC, 10 bit LVDS signal from IC6201(DECODER) is input, and it processes
the color gamut conversion, the skin color correction is processed, and it outputs
FPGA
it with each RGB LVTTL in 10 bits. Moreover, the I2S signal from IC6102 is input,
and the audio delay processing for the picture delay generated since the LCD
TCON+A3C substrate is done.
LVDS This is an LVDS (Low-Voltage Differential Signaling) transmitter IC.
TRANSMIT- This IC converts each 10 bits of RGB of LVTTL from IC7103(FPGA) into a LVDS
TER signal.
This IC is a 16-bit monitor microcomputer which carries M16C/60 series CPU
core. In this IC, the receiving light of R/C, control of the CEC signal, detection of
Monitor-
key, and detection of OPC are performed. Moreover, detection of the error about
UCON
the power supply in IF board and power supply management of the monitor part
are performed.
This IC is 4K bit serial E2PROM of 512 word *8K bit configuration.
4K E2PROM This IC saves the data of a portion with which IC7002 (MONITOR-MICON) is pro-
cessing.
It is power supply IC for supplying the object 5V for the wireless transmission
5V-REG
units of an option. It has short circuit detection and a thermal shutdown function.
This IC is 2 CH-DC/DC-CONV-IC. 15V from a power supply unit is inputted, and
2CH-DC/ 5V and 3.3V which are used within IF board are generated.
DC-CONV Moreover, over-current protection, over voltage protection, short protection, and
RT open short protection etc. builds in the substantial protection circuit.
2CH-DC/ This IC is 2 CH-DC/DC-CONV-IC. 15V from a power supply unit is inputted, and
DC-CONV 1.2V and 1.8V which are used within IF board are generated.

I/O
I2C transactions required for HDCP operation are performed over this I2C bus.
I2C Slave Address input/Transmit Power Sense output pin.
When RESET# is low, this pin is used as an input to latch the I2C sub-address. The level on this pin is
I/O
latched when the RESET# pin transitions from low to high.
When RESET# is high, this pin is used as the TPWR output, indicating that the Rx-port has 5V present.
