Stand by/Start-up Operation (P/A board)

30

Start up operation

When the TV is plugged in, the power board outputs 5V for standby power. Upon receiving this voltage, the
micro (IC8000) outputs the TV_SUB_ON command.
When the power supply receives the TV_SUB_ON signal, it outputs 2 different voltages:

•P15V to the A board on pins 1, 2, and 3 of connector P2.

•24V to the LED backlight power board on pins 7, 8, and 9 of connector P4. This voltage is not used at plug-in.
When the power-on button is pressed and the A board is ready to turn on the display, IC8000 of the A board
outputs the Backlight-on command to LCD Module.

31

Start up operation _ Step 1

32

Start up operation _ Step 1

When the TV is plugged in, the rectifier circuit produces a DC voltage that
travels through the PFC circuit directly to the power switches Q7301 and
Q7302. A separate DC voltage, approx. 40V, produced by D7104 and D7105
serves as start-up voltage to pin 1 of the oscillator IC7301. When the voltage on
pin 1 rises up to a predefined value, IC7301 starts to oscillate and output
switching pulses to Q7301 and Q7302. As current flows through the winding of
T7301, output voltages are generated by the transformer. One of these
voltages, VCC, is used to power pin 10 of IC7301 .
When the power supply starts up, 6V is created by D7407/C7514. This voltage
goes to IC7502 which is a 5V regulator. The start command for this regulator
originates at pin 3 of IC7301.
This pin is internally grounded in normal state and the information is carried to
the secondary side by PC7303. Finally there is around 2.4V on pin 3 of IC7502
to start its operation. Then 5V is output at pins 1 and 2 of the IC.
This voltage (STB5V) is provided to the A board via pin 5 of connector P2.
So when the TV is plugged in, STB5V is provided to A board without an external
trigger signal.

33

Start up operation _ Step 2

34

Start up operation _ Step 2

The STB5V from pin 5 of connector P2 is applied to the Analog ASIC (IC5000) to
supply power to the Main CPU/PEAKS LD4 (IC8000) on the A board. The Analog
ASIC (IC5000) converts the STB5V to STB3.3V and STB1.2V. These 2 voltages
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 and 10 of connector A10.

Upon energizing, IC8000 automatically outputs the TV _SUB_ON command for approximately 12
seconds. This command triggers the output of the P15V source (not shown in the drawing) to the A
board, but the red LED does not light.

The A board performs a self-check operation to determine its communication status. If a defect is
encountered, the unit shuts down and possibly displays a blink code. If all is well, the unit goes to the
standby mode.

When the power on command from the power switch, the remote control receiver or Viera Link
is provided to IC8000 PEAKS LD4, the “TV_SUB_ON” command (2.4V) is output. The
“command is provided to the power supply board via pin 7 of connector P2.

35

Start up operation _ Step 3

36

Start up operation _ Step 3

When the power board receives the TV_SUB_ON signal from IC8000 via pin 7 of connector P2, it outputs 2
different voltages:

1.P15V to the A board on pins 1, 2, and 3 of connector P2.

2.24V to the LED backlight power board on pins 7, 8, and 9 of connector P4.

This command is carried to the primary side of the power supply by PC7302. This voltage turns on the
transistor Q7303 to provide a reference voltage from pin 6 to pin 5 of IC7301.
Therefore the operation of IC7301 changes the switching frequency from standby state to increase the output
voltages.

The TV_SUB_ON command also turns on Q7202 to provide power and turn on the PFC circuit. As a result,
the PFC starts to operate and the output voltages from the transformer T7301 start to rise until the moment
IC7401 starts to operate. This IC monitors the 16V output on the secondary side of the power supply. The
output of IC7401 is provided to pin 4 of IC7301 by PC7301. IC7301 adjust the switching frequency by this
feedback signal. The circuit is designed to maintain a stable DC output of the power supply.

The TV_SUB_ON signal also switches on the transistors Q7402 and Q7403 to output the P15V and 24V
output voltages to other boards.
The 24V is provided to the LCD Module ( LED Backlight Power Supply).
The P15V is provided to the A board.

37

Start up operation _ A board (SUB voltages)

38

Start up operation _ A board (SUB voltages)

The P15V from the P board enters the A board via pins 1, 3 and 5 of connector A02. It is applied to
the Analog ASIC IC5000 and other ICs (Voltage regulators) to generate the SUB-Voltages used for
signal processing operation.
The SUB1.1V, 1.5V, 1.8V, 3.3V, 5V, HDMI3.3V and USB5V are created.
Each voltage regulator is activated by a DCDCEN command created from the P15V source.
So the presence of the P15V source on the A board causes each of the SUB-voltage regulator ICs
to output a DC voltage.

39

Start up operation _ A board (OVP circuit)

40

Start up operation _ A board (OVP circuit)

The Sub voltages are monitored for over-voltage condition. If any of these voltages increases above a
predetermined level, the OVP circuit will be triggered by getting pin 7 of IC5000 to go high.
When pin 7 goes high, the TV_SUB_ON voltage connected to pin 8 is grounded. This disables the circuit that
generates the P15V and 24V on the power supply.

If any abnormality occurs with P15V, the DCDCEN circuit inside IC5000 provides a DC output to turn on the
switch at pin 11. This in turn disables the output of the SUB-Voltage regulator ICs (IC5400, IC5420, IC5440,
IC8100 and IC8101).

When an over voltage condition is detected at plug-in the TV becomes completely disabled and the power
LED remains off.

When an over voltage condition is detected at power-on the TV becomes completely disabled and the power
LED remains on.

41

Start up operation _ A board (PNL,FRC voltage)

42

Start up operation _ A board (PNL,FRC voltage)

The P15V is also used to generate the PNL-Voltage and FRC-Voltages on the A board. IC5000
outputs the Panel VCC On2 signal. IC5300 uses this command to generate the PNL12V.
The PNL12V is provided to the T-con circuit of the LCD Module and ICs (Voltage regulator) to
produce FRC-Voltages.
After that, IC8000 outputs the BL_ON command to the LCD Module through the P board. The BL_ON
command turns on the LED backlight power supply of the LCD Module. If the backlight power circuit
does not work normally, the BL_SOS signal communicates this information to IC8000. At that time,
IC8000 stops outputting the TV_SUB_ON signal and blinks the red power LED 1 times.

Video Process

The main function of the A board is to select and process one of the incoming video
signals. IC8458 and IC4700 are switches that select USB and HDMI signals. The built-in WiFi
module is connected using a USB type terminal.
Video input, Component Video Input, composite video output of the tuner and the other HDMI input
are all connected to IC8000 for selection. The IC has interface circuits that converts each input
signal into digital RGB . The data selected for viewing is then provided to the RGB process circuit
within the same IC for processing.

The RGB 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. After the
process, LVDS (Low Voltage Differential Signaling) is output to IC9100. IC9100, the FRC
(Frame Rate Converter) IC doubles or triples the frame rate to improve focus and eliminate blur.
The output signal is provided to the T-CON for display on the LCD screen.

1. The panel_VCC_ON command turns on the panel 12V regulator to power the T-CON circuit.

2. The PWM_ENB command turns on the PWM generator to produce the control signal for the LED backlight

circuit.

3. The DISPEN command turns on the T-CON circuit to produce the column and row signals to drive the panel.

4. Since the T-CON determines the panel’s drive signals, the Bluetooth Left and Right signals are generated for

transmission to the glasses.

5. The LVDS data is the video signal used by the T-CON to produce the column and row signals to drive the

panel.

6. The IIC data is the communication line between the T-CON and the Main CPU. Data for the PWM signal is also

provided through the IIC line.

7. The LED Driver Control signals, using customer’s OSD, CATS, or artificial intelligence, manipulate the

backlight .

47WT50 & 47DT50 LED Backlight Control

The LED driver board receives 66Vdc and 16Vdc from the power supply via connector P4/LD4. The 16V source is used
to bias the drive IC, IC9500. The 66V source is used bias the LED. The backlight_On command from the same
connector starts the inverter drive signals.

The BL_SOS connection originates at IC8000, the system control IC located on the A board. IC8000 monitors the status
of BL_SOS line to determine the state of the LED drive circuit. During normal operation, IC9500 pulls the BL_SOS line
low to inform IC8000 of the illumination of the LED. Should the drive circuit or an LED array inside the panel become
defective, the BL_SOS line remains or goes high to inform IC8000 of the condition. The TV shuts down and the power
LED emits a one blink error code.

The LED drive circuit is responsible for delivering the current needed to illuminate the panel’s LEDs. A total of 16 FETs
are manipulated on/off by grounding pulses generated within IC9500. To adjust the brightness, the pulses are modulated
to control the on and off time of the FETs.

Unlike other models, a PWM_EN command is provided to the T-CON by the system control IC. The actual PWM signals
are communicated via the IIC bus line of IC8000. The PWM signals are provided to the LED drive circuit via the
connector LD3.

The 66Vdc source and grounding pulses are delivered to the LEDs via t he connectors LD1 and LD4.
When the TV is displaying 3D images, the 3D_ON command is output from IC8000 to change the 66Vdc source of the

power supply to 84Vdc.

Note:

Connector LD1 or LD2 disconnected = Brief (2 seconds) operation with video and sound , then shutdown with one blink
of the power LED
Connector LD1 and LD2 disconnected = Brief operation with black screen and sound , then shutdown with one blink of

The LED driver board receives 66Vdc and 16Vdc from the power supply via connector P4/LD4. The
16V source is used to bias the drive IC, IC9500. The 66V source is used bias the LED. The
backlight_On command from the same connector starts the inverter drive signals.

The BL_SOS connection originates at IC8000, the system control IC located on the A board. IC8000
monitors the status of BL_SOS line to determine the state of the LED drive circuit. During normal
operation, IC9500 pulls the BL_SOS line low to inform IC8000 of the illumination of the LED. Should
the drive circuit or an LED array inside the panel become defective, the BL_SOS line remains or
goes high to inform IC8000 of the condition. The TV shuts down and the power LED emits a one
blink error code.

The LED drive circuit is responsible for delivering the current needed to illuminate the panel’s
LEDs. A total of 16 FETs (Not shown in the drawing) are manipulated on/off by grounding pulses
generated within IC9500. To adjust the brightness, the pulses are modulated to control the on and
off time of the FETs.

Unlike other models, a PWM_EN command is provided to the T-CON by the system control IC. The
actual PWM signals are communicated via the IIC bus line of IC8000. The PWM signals are provided
to the LED drive circuit via the connector LD3.

The 66Vdc source and grounding pulses are delivered to the LEDs via the connectors LD1 and LD4.

When the TV is displaying 3D images, the 3D_ON command is output from IC8000 to trigger the
operation of IC9501 and IC9502. These two ICs are part of booster circuits that amplify the VLED
source from the power supply to a higher level for 3D operation.

Disconnection of connectors yields the same results as the 47DT50 and 47WT50 models.

120Hz Motion Picture Pro4

Even fast-moving scenes are displayed sharply and clearly. With a 60Hz video signal input, 120Hz Motion Picture
Pro4 makes 120 frames/second from 60 frames/second. This increases the frame count to allow natural frame-to­frame transitions, for smooth motion images with high resolution. Motion Focus Technology also reduces flicker and
effectively suppresses blurring and afterimages.

24P Smooth Film

Enjoy naturally flowing 24p films and familiar TV-like quality. This mode optimizes the number of frames of 24p
images recorded from film media such as a Blu-ray Disc™. Advanced source analysis and frame generation produce
smooth images that are faithful to the original.

Dynamic Contrast Ratio 2000000:1

Both high contrast and energy-saving efficiency have been achieved in the IPS LED LCD TV by combining the IPS
panel, which is known for its wide viewing angle, with a bright, energy-efficient LED backlight. Even dark scenes like
night skies are naturally rendered with delicate shades of black. The Intelligent Scene Controller further boosts the
image quality.

Energy Saving Mode

The entire 2011 VIERA line-up meets the Energy Star 4.0 requirements. VIERA TVs satisfy the new criteria for the
Energy Star program of the U.S. Environment Protection Agency (EPA). This testifies to their top-level energy-saving
performance.

Game Mode

In Game Mode, quicker image response increases the enjoyment of video games when a game console is connected
to the TV. What's more, VIERA produces the dark images in video games more clearly. This mode works with the
anti-image retention (wobbling) function, too.

IPS Liquid Crystal Panel

IPS liquid crystal is an abbreviated expression for In-Plane-Switching type TFT crystal, and is a high quality crystal
mode that "is beautiful even when viewed at an angle." With IPS, the liquid crystal molecules rotate on a plane
parallel to the TFT board by a horizontal electrical field, and therefore in principle, it offers superior viewing angle,
color reproduction, and halftone response speed, has little variation in color tone according to the viewing direction

and is capable of displaying a natural image.

Motion Focus Technology

The VIERA LCD TV detects areas with motion and activates backlight blinking for only those areas, greatly
enhancing resolution.

VIERA Image Viewer

It's easy to view full-HD images with the SD card slot. Watch and show your photos right after you take them. Simply
insert an SD card into VIERA to display photos on the large screen. You can also choose the background music and
display effects. It's much more fun when you can view them on a l arge-screen HDTV with family and friends in 1920 x
1080-pixel high definition and a wide 16:9 aspect ratio.

VIERA Link

VIERA Link™ allows the interlinked operation of various AV devices using only the VIERA remote control, by simply

connecting the devices to each other by an HDMI cable.

VIERA Tools

The VIERA Tools user interface makes it easy to use access key functions by pressing a single button. Functions are
easier to use, and there's no complicated operation. The explanation is displayed when you press the function's
button. Just keep pressing the button to use the function immediately.

Wide Viewing Angle

The wide 178° viewing angle ensures clear images even when viewed from an angle. The backlight's wide
transmission aperture enhances the contrast between light and dark, and improves motion-image response.

HDMI ARC

The HDMI Audio Return Channel (ARC) allows the TV to receive picture and audio signals over the HDMI cable, and
then send the same audio out over the same HDMI cable. ARC is part of the HDMI 1.4 specification.

DLNA

DLNA (Digital Living Network Alliance) is a standard that makes it easy for DLNA-certified equipment to share
multimedia content within a home network. A DLNA-certified media server such as a Windows 7 personal computer
with Windows Media Player 12 is required.

Media content that can be played back using DLNA, SD card or USB memory

Certain JPEG, SD-Video, AVCHD, MP4 files, MKV files, MPEG-2 files, MP3 files, AAC files and LPCM files can be
shared using the DLNA feature. Please see the Owner's Manual for the additional requirements.

USB Port

You can connect flash memory, wireless LAN adapter, keyboard, or mass storage devices to the USB ports on the
TV. Ports are USB 2.0, providing maximum 500mA per port.

Easy IPTV

Easy IPTV provides Internet functionality that allows your TV to access popular movie, music and social networking
sites such as Netflix, Amazon VOD, Napster, Pandora, CinemaNow and Facebook. In order to use Easy IPTV
services, the TV needs to be connected to your home network. Not all IPTV services are available depending on
