SECTION 1 - FEATURES AND OVERVIEW
CHASSIS OVERVIEW
The primary circuits in the AZ3FK chassis consist of a Main Board (A Board), Power Supply Board (GL9 for the 32” models and GL10 for the 42” models), the
LCD Panel Assembly includes the Bezel Assembly, the IR Board (H Board) and the TCON Board.

SECTION 1 - FEATURES AND OVERVIEW
CPU: The CPU internal to the MT5389 processor controls all aspects of
the television functions. Input from the user along with monitoring of critical
circuits is also performed by this CPU.
LVDS Transmitter: Integrated into the MT5389 is a Low Voltage Differential
LVDS Transmitter: Integrated into the MT5389 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 circuits located internally to the LCD Panel.
POWER SUPPLY BOARD
There are 2 different Power Supply Boards used in the models in this
manual. The type of board depends on the size of LCD Panel. They are:
●
GL9 for the 32” models
●
GL10 for the 42” models
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 H 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.
SWITCH UNIT
This board contains the power, channel and volume up/down, and menu
buttons.
OVERALL CIRCUIT DESCRIPTION
The
“Block Diagram” on page 9
provides an overview of the AZ3FK
chassis. The following are descriptions of the boards and their functions.
MAIN BOARD
Common to all models utilizing the AZ3FK chassis, the Main Board (A
Board) contains most of the video processing circuitry along with all audio
processing. Control of the television is accomplished via a CPU embedded
within the MT5389 processor. Below is a list of the key components located
on the Main Board.
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).
MT5389 PROCESSOR
This IC performs the majority of the necessary audio and video processing
on the Main Board.
Analog Video Input Switch: All analog video sources are selected and
Analog Video Input Switch: All analog video sources are selected and
A/D converted and scaled (if necessary) to 1920 X 1080p 60HZ resolution.
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.
Audio Processing: Analog audio sources are selected and A/D converted
Audio Processing: Analog audio sources are selected and A/D converted
directly by the MT5389. The audio information is then processed digitally.
Digital audio from the tuner and HDMI sources is also input and processed.
Class D amplifier provides the drive for the speakers.
HDMI Input and Switching: The customer can select the HDMI1 and
HDMI Input and Switching: The customer can select the HDMI1 and
HDMI2 input. Each HDMI input contains a dedicated EDI NVM (not shown)
to provide display information data to any device connected via the HDMI
inputs.
