Video/Audio Signal Process-2
The main function of the A board is to select and process one of the incoming video signals.
IC8601 is just switches of USB signals. The built in WiFi module is connected by USB type
terminal.
Video input, Component Video Input, HDMI input and the composite video output of the tuner
are all connected to IC8000 for selection. The video input signal can be two formats: Video, or Y,
Pb, Pr. A comb filter inside IC8000 converts the composite video signal of the main picture to Y
and C (luminance and chrominance) signals. The signal is then converted to RGB. At the
completion of this process, the format of the composite signal is now the same as a digital 1080i
component signal. If the incoming video is in the 480p, 720p, 1080i, and 1080p format, the Y, Pb,
and Pr signals undergo A/D (analog to digital) conversion. Finally all picture signals are
converted to 1080p.
Digital television reception of the tuner is output in the form of an IF (Intermediate Frequency)
signal. The transport stream from the tuner enters the VSB I/F (Interface) section of IC8000 where
the video signal is extracted and converted to YUV data. The output is provided to the Video Input
I/F for selection. The JPEG data of the SD card enters the JPEG I/F section of IC8000 for
conversion into YUV data and output to the Video Input I/F circuit. The video input interface
outputs the selected picture data to the video process circuit.
This Video Process section of the IC performs all picture control operations such as brightness,
contrast, color, tint, etc. On Screen Display data such as channel numbers, Digital TV closed
caption, and picture adjustments are mixed with the video data. If in 3D mode, it converts to the
right and left pictures. After the process, LVDS (Low Voltage Differential Signaling) is output to
LCD Panel module.

Video/Audio Signal Process (AX800)-3
AX800
4K model have 3 boards for signal process. HE board is only for decoding the H.265/HEVC
format. FR board is for frame rate converting (from 50/60Hz to 100/120Hz).
In A board, IC3500 converts the signal format from Display Port to HDMI. IC3603 and IC1501
receive and transmit the HDMI format signal. IC3603 has a decryption of HDCP1.4. IC1500
converts the signal format from HDMI to LVDS and scales the picture size.
The signal flow in A board is different from the input signal format.
When 4K signal input from the Display port/HDMI2.0 displays in full screen, the Peaks IC just out
the OSD data to IC1500. The OSD data is integrate into 4K signal in IC1500. Then the signal
output to FR board.
When 4K signal input from the Display port /HDMI2.0 displays in the home screen window, that
signal is reduced in IC1500 then output to Peaks IC through IC1501. The Peaks IC integrate the
4K picture into home screen and back to IC1500. Then the signal output to FR board.
When 4K Steam signal (H.265/HEVC) input from the network or USB/SD memory displays by
media player, the Peaks IC output the signal to HE board. HE board decodes the signal and back
to IC1501. Then the signal output to IC1500. Then the signal output to FR board.
When the signal input from other than Display port/HDMI2.0 terminal displays, the signal flow from
Peaks IC to IC1500. Then the signal output to FR board.
*) If the input 4K signal is encrypted by HDCP2.2, only YCbCr4:2:0 profile is supported. (YCbCr4:4:4 is
not supported.) The decryption of HDCP2.2 is in IC1500.

When the TV is plugged in, the power board outputs 5V for standby voltage.
When the power supply receives the TV_SUB_ON signal, it outputs 2 different voltages:
•16V to the A board on pins 1, 2, and 3 of connector P2.
•24V to the LED backlight board on pins 1,3,5,7 and 9 of connector P4.
After A board is ready to display, it outputs Backlight_on command to LED Drive circuit.

When the TV is plugged in, the rectifier start to produce DC voltage which leads
through PFC circuit directly to the power switches Q7301, Q7302. (PFC circuit
IC7201 does not operate at this moment.) Besides this DC voltage is provided also for
D7104, D7105 which provide start voltage to pin 1 of power supply IC 7301. When
the voltage on pin 1 rise up to predefined value IC7301 starts supplyinng of switching
pulses for Q7301, Q7302. Due to this current starts to lead through winding of T7301
T7302 which starts to generate output voltages. One of these voltages VCC is used
for power supplying of the IC 7301 to its pin 10.
When the power supply starts up, the 16V is providing by D7412,13/C7423,40. This
voltage leads to IC7503, which is 5 volts DCDC converter. This converter needs to get
starts commands, which is provides by IC 7301 pin 3. This pin is internaly grounded in
normal state and the information is carried to the secondary side by PC7303. Finally
there is input signal on pin 6 of IC7503 for start its operation.
This voltage (STB5V) is provided to A board via connector P2 pin7. So if the TV is
plugged in, STB5V is provided to A board without trigger signal.

The STB5V from pin7 of connector P2 is applied to the Analog ASIC (IC5000) for
supplying power to the Main CPU/PEAKS (IC8000) on the A board. The Analog ASIC
(IC5000) converts the STB5V to STB3.3V. This voltage energize and prepare the
microprocessor (CPU) for program execution. The STB3.3V from the Analog ASIC (IC5000)
is also applied to the remote control receiver and the power LED on the K board through
pins 5 of connector A10/K10.
When the Power Switch on, the key3 signal is grounded. (#1)
The IC8000 lights on the RED LED and is ready to power on the TV by receiving the Power
switch on, Remote on, Viera Link and so on. This is a standby state.
(#1)Only North America model: Power switch on is no need, automatically this procedure is
operated after the TV is plugged in. But the RED LED does
not light.
When the power on command from the power switch, the remote control and so on is
provided to IC8000 PEAKS, IC8000 first outputs the “TV_SUB_ON” command. The
“TV_SUB_ON” command is provided to power board via pin 9 of connector P2.
(#) Just after transition to Stand-by mode, the TV_SUB_ON(16V) output for few minutes.

When the power board receives the TV_SUB_ON signal from IC8000 via pin 9 of
connector P2, it outputs 2 different voltages:
16V to the A board on pins 1, 2 and 3 of connector P2.
24V to the LED backlight board on pins 1,3,5,7 and 9 of connector P4.
This command is carried to the primary side by PC7302. This voltage is leaded to Q7303
whcih provide reference voltage from pin 6 to pin 5 of IC7301.
Therefore the operation of the IC 7301 changes the switching frequency from standby
state to working state and output voltages rise up.
Besides the ON command is connected to the Q7202 which provide power supply VCC
of PFC circuit. The PFC starts to operate then.
Output voltages from transformer T7301 start rising up until the moment when IC7401
started to operate. This IC measures the 16V line output in the secondary side. The
output of this IC is provided by PC7301 to pin 4 of IC7301. IC7301 adjust the switching
frequency by this feedback signal.
The TV_SUB_ON signal also switches on the Q7402-04 to provide output voltages
(16V and 24V ) to other boards. The 24V is provided to the LCD Module ( LED Backlight
Power Supply ). The 16V is provided to the A board.
