Chassis Layout
Model Introduction
The KLV-40ZX1M is an ultra-thin LCD monitor measuring a meager 1”-
1/8” (9.9mm) in depth and weighs only 26 pounds. As mentioned, this
is a monitor, so it does not contain a RF tuner to receiver television
programming. Furthermore, there is only one video/audio input on this
model - the digital high-quality HDMI input. Therefore, to receive and
display channel programming a STB or DVR with an internal RF tuner
must be connect to the HDMI input. The monitor can also be connected
to a DVD or Blu-ray player through the HDMI connector to receive high-
quality video and audio.
The LCD panel is a Full High-Definition 1080p resolution panel. The
backlight is produced using a Wide Color Gamut LED edge light system.
This system provides high contrast ratio with more accurate color and
blacker blacks. To further enhance the color reproduction a 10-bit
processor and 10-bit panel are combined in this model.
The model also includes the Motionflow™ 120Hz technology which
enhances sharpness and delivers smooth motion for fast-action sports
and movies. And finally, this model contains the BRAVIA® Engine™ 2
fully digital video processor.
A/V Input Connection
HDMI
This input provides reception of uncompressed digital video and multi-
channel audio over a single cable connection.
PCB and Component Descriptions
Reference Figures 1-1 & 1-2
B-Board
The circuits located on the B-Board perform all Video and Audio processing
functions. It also contains all the microprocessor control circuits. The
following circuits are included on this board.
• BE (TV) Microprocessor
• TRIDENT Processor
- Video Signal Processing
- HDMI Signal Processing
- Scan Converter
- HDCP Processing
• Audio DSP
• Audio Amplifier
• Temperature Sensor
LD1-Board
This board contains three power converter circuits to drive the top, bottom,
left, and right edge LED backlight system. The drive outputs for the LED
system are between 56Vdc and 95Vdc.

Chassis Layout
GS1-Board
Except for some regulator circuits on the B-Board, the GS1-Board is the
power supply system board, which includes the following components
and circuits.
• Main Power Supply
o 12V for Audio, BT3-Board, and LD1-Board Circuits
• Standby Power Supply
o 3.3V for standby circuits
• 390V for Backlight Circuits (LD1-Board)
• 18V for Backlight Circuits (LD1-Board)

TV-STAND
The TV-STAND contains the speaker system which includes left, right,
and sub-woofer speakers. The speaker system is replaced as assembly
or speaker module.
NOTE: The LCD Panel (video) will work fine with the TV Stand disconnected.
The audio output mute lines on the BM3-Board are activated.
LCD Panel Assembly
The LCD Panel Assembly includes the LCD Panel, BT3-Board (TCON/
HFR), and LED Backlight system.
The LCD Panel contains the actual liquid crystals, color filters, and
polarizers. The liquid crystals are manipulated by the applied voltage to
pass a specific amount of light - from the backlight- depending on the
level of voltage applied. The panel resolution on the EX1S chassis model
is 1920 X 1080 lines. This is considered a 1080P Full High-Definition
model.
The BT3-Board (TCON & HFR) performs all the control, timing, charge,
and discharge functions driving the operation of the LCD Panel. The HFR
(High Frame Rate) section performs the 60Hz to 120Hz frame refresh rate
conversion.
All-White LED Edge Backlight System
Reference Figure 1-3
The top, bottom, left, and right edge LEDs generate the white light that is
captured and evenly spread across the panel by a Light Guide Plate. The
captured light then passes through the liquid crystals in the LCD Panel.
The light guide operates in the same way a fiber optic cable operates.
There is a light source which generates the light and the fiber optic cable
(glass fibers) retains the light within its boundaries.
