SECTION 1 - FEATURES AND OVERVIEW
CHASSIS OVERVIEW
The primary circuits in the AZ3F chassis consist of a Main Board (BAPS Board), Power Supply Board (GL6 Board for the 40” and 46” models, and GL7 Board
for the 55” models), the IR Board (HL Board), the 3D IR Emitter (HEM3 Board), the Wireless LAN Card, the Switch Unit, and the LCD Panel assembly which
includes the TCON Board.

SECTION 1 - FEATURES AND OVERVIEW
OVERALL CIRCUIT DESCRIPTION
“Block Diagram” on page 12
provides an overview of the AZ3F chassis.
The following are descriptions of the boards and their functions.
MAIN BOARD
Common to all models the Main Board, designated as the BAPS Board,
contains the TV control, video, and audio processing circuitry. All these
functions are accomplished using the X-Reality Processor IC9000.
TUNER
The tuner is a combination ATSC/NTSC unit. It can receive traditional
analog NTSC signals via cable or terrestrial along with ATSC digital signals
via terrestrial (8VSB) or cable (64 or 256 QAM).
X-REALITY PROCESSOR
IC9000 performs the majority of the necessary audio and video processing
on the Main Board.
TV Microprocessor: The CPU internal to the X-Reality processor controls
TV Microprocessor: The CPU internal to the X-Reality processor controls
all aspects of the television functions. Input from the user along with
monitoring of critical circuits is also performed by this CPU.
Digital Audio and Video Decoder: The MPEG2 and Digital Dolby audio
Digital Audio and Video Decoder: The MPEG2 and Digital Dolby audio
streams are received from the tuner for decompression. All video sources
which are not native 1920 X 1080p 60HZ are scaled to this resolution.
Digital audio content is output to the class D amplifier for processing and
amplification.
HDMI Input and Switching: The customer can select the HDMI1, HDMI2,
HDMI Input and Switching: The customer can select the HDMI1, HDMI2,
HDMI3, HDMI4 input via the HDMI switch IC5500. Each HDMI input contains
a common EDI NVM (internal to IC5500) to provide display information data
to any device connected via the HDMI inputs.
LVDS Transmitter: Integrated into IC9000 is a Low Voltage Differential
LVDS Transmitter: Integrated into IC9000 is a Low Voltage Differential
Signaling (LVDS) transmitter. This circuit converts the 8-bit parallel RGB
video information into a set of high speed serial lines for noise-free
transmission to the TCON Board circuits located internally to the LCD Panel.
Scan Converter: Signal processing circuit that performs resolution
conversion (aspect ratio) and interlaced to progressive scan (IP) conversion.
AUDIO AMPLIFIER
The main speaker audio amplifier (IC4601) and sub-woofer amplifier
(IC4701) amplifies the digital audio output of the X-Reality processor and
sends it to the speakers.
TEMPERATURE SENSOR
The temperature sensor detects over-temperature conditions on the Main
Board, LCD Panel, or ambient room temperature and sends the shutdown
signal to the processor.
POWER SUPPLY BOARD
There are different Power Supply Boards used in the models in this manual.
The type of board depends on the size of LCD panel. They are:
●
GL6 Board (40” & 46”)
●
GL7 Board (55”)
There are 3 distinct sections on the power supply:
Standby Supply: Continuously operational as long as AC power is applied,
Standby Supply: Continuously operational as long as AC power is applied,
the standby supply generates 3.3V for the circuits requiring power while the
unit is turned off. An unregulated 19V line is present to provide power to the
main relay, PFC and main power supply at turn-on.
Main Supply: Once the power supply receives a power-on command from
Main Supply: Once the power supply receives a power-on command from
the CPU on the Main Board, the main switching supply is turned on to
provide a regulated 12V source and Audio 12V.
Converter: Generates the B+ and B- voltages for the LED backlights.
Converter: Generates the B+ and B- voltages for the LED backlights.
IR BOARD
Designated as the HL Board, the IR Board contains the power, standby, and
timer LED’s that are located on this board along with the IR remote receiver
and light level sensor.
