Overall Block Diagram

The TC-26/32LX60 and 600 series LCD Direct View TVs differ from previous

models in that all signal processing is accomplished on the A board. The

video processing function that had been previously accomplished by the DG

board is now performed on the A Board by IC4002. This IC serves as the

Main micro and Video /Audio Panel controller. IC4004 is a Field

Programmable Gate array that is responsible for the pixel conversion and

addressing of the Active Matrix display within the LCD Panel. This IC also

contains the low voltage differential signaling (LVDS) transmitter used for the

conversion of the 8-bit RGB video into a differential RGB output signal. The

LVDS receiver on the LCD panel converts the differential RGB output signal

from the A board into an 8-bit RGB signal that is output to the LCD Panel.

Board Layout

Non - Serviceable Non - Serviceable

Non - Serviceable

This is the board layout of the TC-LX600 LCD Television. The P board, DT

board, and A board are non serviceable. The G board, AP board, and V

board are serviceable.

Board Layout Pictorial

P Board – The Power unit is responsible for generating the Standby 7V, 10V, and

24V, which provides input to some of the regulators on the AP Board. It also

generates the switched 24V inverter voltage.

AP Board – Comprised of all secondary voltages which include the Main 9V,

SUB5V, Sound 20V, Panel 12V, Standby 3.3V.

A Board – Comprised of all AV inputs and the HDMI interface with the exception

of one AV jack which is located on the G board. All audio and video processing is

performed on this board.

G Board – Contains an additional AV connector and the Headphone Jack.

ATSC tuner – The Digital Tuner plugs into a connection on the A board.

V Board - Remote sensor and Power LED.

Board Description

Board Main

The A board (Main Board) is a self contained board responsible for the

input selection, and processing of all Audio and Video input signals. All

audio and video connections with the exception of those found on the G

board reside on this board. The G board contains an additional AV Jack,

headphone jack, and front panel switches. The unit is equipped with a

single ATSC tuner which plugs directly onto the A board. The LX60

features a single HDMI interface while the LX600 offers two.

The connectors and pin outs provided in this diagram are, for the most

part, the only available access points for board level repair

troubleshooting.

Board Video Processing

Video processing is performed on the A board. The A board incorporated

in these models is now responsible for signal processing, and system

control operation. The video processing function that had been performed

by the DG board of the previous models is now accomplished on the A

Board by IC4002. This IC is also responsible for selectively switching all

video inputs (Tuner, Component, Composite, S-Video, and HDMI). The

HDMI video is converted to an eight-bit YUV signal by the HDMI IF

receiver (IC5004) before being output to the video selector. IC5002

provides the copyright protection for the incoming HDMI signals. The

ATSC interface (DT board) processes the ATSC, NTSC, and QAM television

signals. The analog NTSC and digital ATSC or QAM signal of the DT board are

output to the A board via the connector DT12/A12. IC4002 is responsible for

processing all video, which includes image resizing, noise reduction, I/P

conversion and Gamma adjustment control. Although selected by a

different IC, the audio processing function is also performed by IC4002.

OSD is also generated by IC4002 and mixed with the video signal before

being output to IC4004. IC4004 is a Field Programmable Gate array

responsible for the pixel conversions and addressing of the Active Matrix

display within the LCD Panel. This IC also contains the low voltage

differential signaling (LVDS) transmitter, used for the conversion of the 8-

bit RGB video into a differential RGB output signal. The LVDS receiver

on the LCD panel (not shown in the drawing) converts the differential

RGB output signal from the A board into an 8-bit RGB signal that is

provided to the LCD Panel.

Board Audio Processing

Audio processing is performed on the A board. Audio signals from the

DVI, Component, and the Composite video input enter the Audio Switch

IC2006 where the desired input is selected. HDMI Audio is processed

and converted into a one bit digital audio format by the HDMI IF receiver,

IC5004. The HDMI audio bypasses the audio switch and enters IC4002

for selection and processing. The output of IC2006 is processed within

the Video/Audio controller IC4002. The Audio Output from the

Video/Audio controller is output to the speakers via the Audio Amplifier

IC2001 and pins 1 through 7 of connector A7. The Headphone amplifier

is activated when the headphones are plugged into the headphone jack

located on the G board. This action mutes the audio to the speakers by

disabling the Audio output Amplifier IC2001.

Power On Sequence

1.The Standby 7V (STB_7V) is generated on the P board (non- serviceable) when AC power

is applied. This can be measured on Pin 3 of Connector AP4/A4.

2.The STB_7V is regulated to 3.3 V on the Main board and applied to the Main Video and

Audio Controller IC4002.

3.Power on command by the remote control is not possible until the main power switch is

activated. When the Main Power Switch (AP Board) is activated, a active low ALL_OFF

signal is provided to the base of Q1151 via pin 7 of the connector AP4/A4. As a result

Q1151 turns on and a low is applied to the Key Scan Power input pin of IC4002. This

causes the unit to turn on, display a raster and become fully operational. The remote

control commands are now received and processed by the main unit. To continue

having full access via the remote control, the unit must be powered off by the remote

control, not by the power switch located on the main unit.

4.The Sub-On signal is issued by IC4002 on pin 8 of connector AP4. This signal is

responsible for pulling the contacts on the AC relay on the Power Board.

5.The Main_On signal is issued by IC4002 and provided to the AP board via pin 6 of

connector AP4/A4. It enables the Main 9V, Main 5V, and the Sound 18V (Not Shown in

the diagram) secondary power sources of the AP board. The Main_On signal is also

responsible for enabling the Main 3.3V regulator needed to power IC4004.

6.IC4004 provides the Panel_On signal that enables the Panel 12V regulator on the AP

board. It also provides the Inverter_On signal that enables the DC to AC inverter

circuitry on the LCD Panel.

7.The Inverter PWM signal and Current signal control the output voltage of the DC to AC

inverters that is used to power the CCFLTs. Increasing the on time of the INV_PWM

signal, which can be seen on pin 5 of connector A5, will increase the brightness of the

backlighting on the LCD Panel.

8.The INV_SOS signal is issued by the logic that resides on the LCD Panel if there is a

problem with the panel of inverter power supply.
