1-2. Connecting the TV to a home antenna terminal
Caution: When connecting, ensure that the TV is switched off.
The antenna requirements for good color television reception are more
important than those for black & white television reception. For this reason, a good quality outdoor antenna is strongly recommended.
The following is a brief explanation of the type of connections that are
provided with the various antenna systems.
1. A 75-ohm system is generally a
round cable with F-type connector
that can easily be attached to a terminal without tools (commercially
available).
75-ohm coaxial cable (round)
2. A 300-ohm system is a flat "twinlead" cable that can be attached to a
75-ohm terminal through a 300-75-
300-ohm twin-lead cable (flat)
ohm adapter (commercially available).
Notes:
• The 75-ohm coaxial cable is recommended.
• TV memory for channels is empty at shipment.
To receive channels, use the CHANNEL SETTING menu.
F-type connector
75-ohm coaxial cable
■ Cable TV (CATV) connection
• A 75-ohm coaxial cable connector is built into the set for easy hookup.
When connecting the 75-ohm coaxial cable to the set, screw the 75ohm cable to the antenna input terminal (ANT).
• Some cable TV companies offer "premium pay channels". Since the
signals of these premium pay channels are scrambled, a cable TV
converter/descrambler is generally provided to the subscriber by the
cable TV company. This converter/descrambler is necessary for normal viewing of the scrambled channels. (Set your TV to channel 3 or
4, typically one of these channels is used. If this is unknown, consult
your cable TV company.) For more specific instructions on installing
cable TV, consult your cable TV company. One possible method of
utilizing the converter/descrambler provided by your cable TV company is explained below.
Please not :An RF switch provided with two inputs (A and B) is
required (commercially available).
"A" position on the RF switch (commercially available):
You can view all unscrambled channels by using the TV's channel
buttons.
"B" position on the RF switch (commercially available):
You can view the scrambled channels via the converter/descrambler
by using the converter's channel keys.

CHAPTER 6. HARDWARE DESCRIPTION
1. CIRCUIT DESCRIPTIONS
1-1. TV TUNER UT13 (VT2U5JF559)
The VT2U5JF559 is a TV tuner of the NTSC system which is popularly
used in the U.S.A. (PIF45.75MHz)
It operates on the power voltage of 5V (6, 7 pins) and the tuning voltage
of 30V (9 pin). The voltage of 30V is boosted and generated by the PU1
peripheral circuit.
Tuning is controlled by the I2C bus (4, 5 pins), and the video signal
(1Vp-p) is outputted to 19 pin and supplied to the video decoder U19.
Also, the FM signal (about 50mVp-p) of sound SIF is outputted to 15
pin, and supplied through SIF_AMP (Q11) to the audio processor U9.
The audio monaural output (16 pin) is not used in this model.
The AGC voltage output (7pin) falls below 4.5V when the electric field
becomes 60dB or more. This voltage is used in automatic tuning. The
twelve channels of stronger wave have priorities to be selected and
saved in the memory.
When tuning is performed correctly, the AFT voltage (12 pin) becomes
about 2.4V. (100KHz/1V)
This voltage is controlled by the microprocessor to be 2.4V, performing
correct tuning.
1-2. VIDEO SIGNAL PROCESS
1-2-1. AV input selector U35 (CXA2069Q)
This AV selector IC selects the external composite video signal input
pin, the S pin input, the video, and the sound signal from the TV tuner.
Selection is made with the I2C of 33, 34pin.
The output composite signal is supplied to the video coder U19
(VPC3230D) through the 3-dimentional Y/C separations IC (U17) .
The input from the S pin is supplied directly to U19.
The UPD64084 is an adaptive Y/C separation IC used for the purpose
of separation of the composite signal of the brightness signal of tuner
images and the color signal into the bright signal and the color signal.
The composite video signal outputted from the AV input selector U35
(53 pin) is inputted to 93pin through the low pass filter (U29) circuit.
The brightness signal separated in Y/C is outputted from 89pin ( (AYO),
and the color signal is outputted from 88pin (AC0). They are supplied to
the video decoder (U19) through the low pass filter (U24) and the band
pass filter (U22).
1-2-3. Video decoder U19 (VPC3230D)
The VPC3230D is a video decoder IC which converts Y/C separation
signals into digital Y/Pb/Pr signals.
The composite video signal is inputted from the tuner and the external
input pin, and Y/C separated, and inputted from 75pin and 72pin. The
Y/C signal from the S pin is directly inputted to 74pin and 71pin, and
processed as the S signal, and converted into the digital Y/Pb/Pr signals and outputted.
The output is inputted to the IP conversion U33.
1-2-4. Video A/D Converter U37 (MST9883C)
This is an A/D converter which converts analog Y/Pb/Pr signals into digital RGB signals. The Y/Pb/Pr signals inputted from the component
input pin are passed through the low pass filter (U46) to 48 pin, 43 pin,
and 54 pin, and converted into digital RGB signals and inputted to the
IP conversion U33.
1-2-5. IP conversion U33 (FLI2310)
The FLI2310 performs IP conversion of the interlace digital Y/Pb/Pr signal from the video decoder (U19) into the progressive digital RGB signal, and performs IP conversion of the digital RGB signal from U37, and
outputs it to the scaler U34.
1-2-6. Scaler & CPU U34 (gm1501)
The gm1501 allows direct input of the analog RGB signal/digital DVI
signal for PC, and converts the digital RGB input into the specified
screen size, and outputs the LVDS signal to the LCD module.
It is also provided with microprocessor functions, and controls many
IC's according to Flash memory (U42) information.
As additional functions, it is provided with PC input, PinP (Picture in Picture) of tuner and external video input, frame rate change, and OSD
(On-Screen Display).
1-3. AUDIO SIGNAL PROCESS
1-3-1. Audio processor U9(MSP3440G)
The MSP3440G is an audio processor which processes audio signals.
The MSP3440G decodes the SIF signal input (67pin) of the tuner output
into a proper format such as stereo or monaural, sets the sound quality
by Bass and Treble, sets the sound volume (fixed) according to each
input source, and performs other audio signal processes.
The external input signal (56, 57pin) selected by the input selector U35
(CXA2069Q) and the PC AUDIO input (47, 48pin) are selected, and
delay and Dolby signal process are performed, and they are outputted
from 27 and 28pins to the speaker amplifier and from 24 and 25 pins to
the headphone amplifier.
They are also outputted from 36 and 37pins through the input selector
U35 (CXA2069Q) to the external output pin.
1-3-2. Digital audio delay U6 (NJU26901)
The NJU26901 is a delay IC which delays the output time of audio signals.
When an audio signal is inputted to 1pin, it performs delay process of
the specified time and outputs the signal to 7pin.
1-3-3. Digital audio processor U13 (NJU26106)
The NJU26106 is a digital audio processor which decodes stereo audio
signals.

outputted from 3pin.
1-3-4. Speaker driver U1 (LA4636)
The LA4636 is a power IC of the BTL system, which drives two speakers: L and Rch of 8Ω. Audio signals inputted at 2 and 4 pins are outputted to 8 - 9 pins and 11 ?
12pins in reverse polarity of L and Rch.
The voltage gain is fixed to 35dB. However, mute can be applied by the
control voltage at 6pin.
The voltage at the standby pin (5pin) is controlled by the headphone
detection signal from the headphone pin to shut off the speaker output.
1-3-5. Headphone amplifier U5 (LM4911)
The LM4911 is an audio power amplifier which allows gain adjustment
by an external resistor.

1-4. INVERTER UNIT
(HIGH VOLTAGE SIDE: RDENC2159TPZZ,
LOW VOLTAGE SIDE: RDENC2161TPZZ)
For lighting the 14-lamp backlight (striplight) of the LCD panel.
It allows ON-OFF control and brightness (Duty light control system)
control.
The operating power source is supplied from the 12V output connector
CN201 for the power unit inverter directly with the cable.
The inverter PWB is composed of two PWB's: one on the high voltage
side with the control and the output circuits and the other on the low
voltage side for detection of current, and is connected with FFC.
15pin of J13 connector on the main PWB is for ON/OFF control (ON at
5V) of the backlight, and 9pin is for control of the brightness adjustment.
Brightest at 0V. The higher the voltage is, the darker the brightness is.
(Max. 5.0V)
The protection circuit is provided to stop operation when any trouble
occurs in the lamp.
Note: The inverter unit supplies a high voltage of max. 2,000V to the
lamp by the boosting transformer.
Be sure to keep your hand away from the output connector, etc.
when the machine is conducting. It is very dangerous. Use great
care when servicing.
1-5. AC POWER UNIT (DPS190DP)
The PDS190DP is a power unit of multi outputs (12V, 5V, 3.3V, sub 5V)
of general output 190W. The input power specification is AC100 ? 240V
(50/60Hz).
It is provided with the AC input connector CN1, the inverter output connector CN201, and other I/O connector CN202.
The CN201 is used for output of 12V for the inverter. 1- 5 pins and 11 ?
15 pins are GND, 6 ? 10 pins and 16 ? 20 pins are at 12V.
The CN202 has 12V pin (1, 2pin) for the circuits, 5V pin (5, 6pin) for the
circuits, 3.3V pin (9, 10pin) for the circuit, 5V pin (13pin) for the sub
power source, the ON/OFF control input PSON (15pin), the power status output PG (16pin), and the other pins (3, 4, 7, 8, 11, 12, 14 pin) for
GND.
5V and 3.3V are generated from 12V by the DC-DC converter circuit
inside the power source. Protection circuits are provided against an
overvoltage, an overcurrent, and a high temperature. When the power
is shut down, disconnect the AC cord and connect it again to reset.
Note: While AC power is supplied, a voltage is provided to the heat
sink (HS1, HS2, HS3) on the primary side. Use great care to
avoid an electrical shock when servicing. (The heat sink HS4
near the output connector is at GND level, and safe when
touched.)
1-6. REMOTE CONTROL
This is a remote control of infrared system.
When the remote control key is pressed, infrared rays are radiated in
pulses. (Remote control code)
The remote control light receiving section U7 is provided in the front
side of the unit.
When it receives infrared pulses, it converts infrared rays into a voltage.
The information is transmitted to the microprocessor to perform proper
processes.
PVT: Fan lock1(GPIO_G09_B3), Fan lock2 (GPIO_G04_B0)
when "High", then system enter "Standby mode"
3. AFT change:
DVT: AFT/AGC use the same pin to detect (LBADC_IN2) , & need use GPIO_G07_B2 to select AFT or AGC
PVT: AFT use LBADC_IN2; AGC use LABDC_IN3
4. Audio delay for AV OUT:
DVT: no delay
PVT: need to modify MSP to delay audio to AV_out, ProII cant output to AV_OUT
5. AV switch Tuner/ AV1/AV2 path change:
Tuner: DVT: V5 (CXA2069Q)
PVT: TV port (CXA2069Q)
