SECTION 1 - SAFETY AND FEATURES
SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly soldered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are “pinched” or touching high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely
certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out
to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and
recommend their replacement.
6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer.
7. Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.

LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from all exposed
metal parts to any exposed metal part having a return to chassis, must not exceed
0.5 mA(500 microamperes). Leakage current can be measured by any one of three
methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instructions.
2. A battery-operated AC milliampmeter. The Data Precision 245 digital
multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a VOM
or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so
analog meters must have an accurate low voltage scale.
4. The Simpson’s 250 and Sanwa SH-63TRD are examples of
passive VOMs that are suitable. Nearly all battery-operated digital
multimeters that have a 2 VAC range are suitable (see Figure A).
Figure A. Using an AC voltmeter to check AC leakage.
HOW TO FIND A GOOD EARTH GROUND
A cold-water pipe is a guaranteed earth ground; the cover-plate retaining screw on
most AC outlet boxes is also at earth ground.
If the retaining screw is to be used as your earth ground, verify that it is at ground
by measuring the resistance between it and a cold-water pipe with an ohmmeter.
The reading should be zero ohms.
If a cold-water pipe is not accessible, connect a 60-to 100-watt trouble-light (not a
neon lamp) between the hot side of the receptacle and the retaining screw. Try both
slots, if necessary, to locate the hot side on the line; the lamp should light at normal
brilliance if the screw is at ground potential (see Figure B).

SECTION2-SOFTWAREREQUIREMENTS
OVERVIEW
There are 2 reasons for updating the software on the TVs.
●Software updates for customers
These updates are for enhancements or improvements that
have been made to the software after the TV was released.
●Software update for servicers
These updates are specically for servicers to use during a
service call.
SOFTWARE UPDATES FOR CUSTOMERS
The subject of software updates is a very important. The televisions
of today have advanced to the point where they are not simply a
television anymore. They are evolving into devices that are designed
to integrate with numerous other devices found in the home. Some
examples are: Portable audio and video devices, still cameras, home
computer networks and accessing the internet to name a few.
Communications with these varying devices requires that the
television be compatible with varying communications protocols.
Although standards are detailed for each of these protocols, the real
world dictates that occasional errors may occur that could prevent
devices from operating or communicating properly.
Keeping the software in the television up-to-date is a procedure that
is normally handled by the owner of the television. Most customers
who own computers and other digital devices are familiar with and are
accustomed to updating the software in their products. If a customer
contacts the Sony Customer Support Center and it is deemed to
be correctable with a software update, the issue is handled at the
customer level.
KDL-32EX725/40EX725/55EX72512
Page 19
SECTION 2 - SOFTWARE REQUIREMENTS
SOFTWARE UPDATES FOR SERVICERS
The models in this manual utilize a “generic” type Main Board. In
the past, many different Main Boards needed to be stocked due to
differences in software requirements. The software loaded on the
board was specic to the model and its features along with the type
of LCD panel installed during production.
Replacement Main Boards are now stocked with basic software.
Once the replacement board is installed in the unit, the most current
software needs to be installed using a USB thumb drive containing
the necessary software downloaded.
This new method of supplying Main Boards signicantly reduces the
complexity of replacing LCD panels and Main Boards. Information
about the LCD panel is stored on the T-CON circuits. This information
is automatically loaded onto the Main Board when the TV is powered
up. With the correct software version the Main Board and/or the
T-CON or LCD panel can be replaced more efciently.
In addition to software installation, service adjustment information
may need to be modied or veried to complete the service of the
TV. Service adjustment information is covered in “Section 7 - Service
Adjustments” on page 66.
SOFTWARE UPDATE RESPONSIBILITY
Software updates are designed to be performed by the customer.
Warranty repairs in which the issue can be resolved by a software
update are not reimbursable. Most issues involving software
updates are handled by the customer service center and should not
be directed to an authorized service center. It is the responsibility
of the servicer to prevent service calls for issues that involve
software updates. Exceptions to this are certain cases whereby the
customer is unable or unwilling to perform the task. In this situation,
the servicer will be notied and receive the proper authorization for
reimbursement.
It is the servicer’s responsibility, however, to make certain that any
TV requiring a legitimate service is running the latest software
version and to install it if necessary.

Page 20
SECTION 2 - SOFTWARE REQUIREMENTS
CHECKING THE SOFTWARE VERSION
The easiest way to check the version of software that is currently on
the TV is to access the Contact Sony screen by using the customer
menu.
FIGURE 2-1. EXAMPLE OF SOFTWARE VERSION
LOCATED ON THE CONTACT SONY SCREEN
EXAMPLES OF SOFTWARE CORRECTABLE
SYMPTOMS
Most symptoms that are correctable by software updates involve
communications issues with other devices or minor glitches in
the operation of a specic function. Below is a list of some of the
symptoms that may be corrected with a software update:
●Fluctuations in picture brightness
●Intermittent picture freezing or noise
●Problems with certain inputs (especially HDMI)
●Intermittent or distorted audio
●Erratic remote control operation
●Unit turns on and off by itself
●Loss of color
●Internet connectivity

SECTION 3 - CHASSIS OVERVIEW
OVERALL CIRCUIT DESCRIPTION
“Figure 3-5. Overall Block Diagram” on page 20 provides an overview
of the AZ2-F chassis. The following are descriptions of the boards
and their functions.
MAIN BOARD
Common to all models the Main Board, designated as the BATV
Board, contains the TV control, video, and audio processing circuitry.
All these functions are accomplished using the X-Reality Processor.
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 all aspects of the television functions. Input from the user
along with monitoring of critical circuits is also performed by this
CPU.
HDMI Input and Switching: The customer can select the HDMI1,
HDMI2, HDMI3, HDMI4 input. Each HDMI input contains a common
EDI NVM (not shown) to provide display information data to any
device connected via the HDMI inputs.
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 T-CON 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 audio amplier (IC4601) amplies 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.
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 amplier
for processing and amplication.
KDL-32EX725/40EX725/55EX72517

SECTION 3 - CHASSIS OVERVIEW
POWER SUPPLY
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:
●G10A-Board (32”)
●G4B-Board (40”)
●G6A-Board (55”)
Note:the G8A in the 55” models is the Power Supply Board
for the Panel LED backlight system.
There are 2 distinct sections on the power supply:
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 the CPU on the Main Board, the main switching supply is turned
on to provide a regulated 12V source and an regulated 24V source
for the LED power supply circuits.
POWER SUPPLY FOR BACKLIGHT
LD BOARD (LED DRIVER BOARD)
The LED Driver Board is controlled by the T-CON/HFR Board to
perform overall backlight power-on, backlight level, and local dimming
functions. This board takes the 24V from the Power Supply Board
(or G8A Board for the 55” models) and develops the negative and
positive voltages to directly drive the LEDs in the panel assembly.
3D IR EMITTER
Designated as the HEM2 Board, this board is the internal 3D IR
Emitter.
SWITCH UNIT
This board contains the power, channel, and volume up/down and
menu buttons.
MOTION SENSOR BOARD
Designated as the HMS3 Board, the Motion Sensor Board contains
the circuits for the Motion Sensor. The Motion Sensor detects when
there is movement in front of the TV. If there is no movement in
front of the TV after a predetermine amount of time the backlight is
turned off (audio present). After an extended period of time the TV is
completely turned off.
SYSTEM
The G8A-Board is the Power Supply Board for the Panel LED
backlighting system (including the LED Driver Board) for the 55”
model only. 390V, 19V, and 12V are applied to the board from the
G6A Board to develop the 24V. The 24V is applied to the LD Driver
board.
KDL-32EX725/40EX725/55EX72518
IR BOARD
Designated as the HLR2 Board, the IR Board contains the power,
standby, and timer LED’s are located on this board along with the IR
remote receiver and light level sensor.

Self Diagnosis
Supported model
The models in this manual contain a self-diagnostic function. If an
error occurs, the standby LED will automatically begin to ash. The
number of times the LED ashes translates to a probable source of
the problem.
A history of the errors is stored on the Self Check diagnostic page as
shown in ”Figure 4-4. Sample Self Check Diagnosis Page” on page
35. This page can be used to review the failure occurrence data stored
in memory to reveal past problems and how often these problems
occured. If there is more than one error, the standby LED will identify
the rst of the problem areas. If the Self Check screen displays a “0”,
no error has occurred.

SECTION 4 - TROUBLESHOOTING
2X Blink - Main Power Error
A 2X protection mode blink pattern can be activated due one of the
following defects.
●Loss of REG12V (LVP)*
●Loss of -125V (Single Line)
●Excessive -125V Level (OVP)*
●Loss of Power-ON Signal
●Excessive PFC Voltage (OVP)
●Excessive PFC Temperature (OTP)
*Low Voltage Protection (LVP)
*Over Voltage Protection (OVP)
A loss or excessive condition of the REG12VDC secondary voltage
from the main power supply IC6351 will cause a 2X blink pattern on
the standby LED. The 12Vdc can be checked at CN6704/pin 16.
If the measurement is 0V or rises above 12Vdc (approaches 15V)
before the TV shuts down the Power Supply Board is defective.
regulate down to between 89V and 125V depending on the Backlight
adjustment in the User Menu. If one of the negative supplies is 0V
or rises above -175V before shut-off then the Power Supply Board is
defective, replace it to x the problem.
A defective X-Reality processor on the Main Board or Switch circuit
on the Power Supply Board will cause a loss of the Power-ON signal
(2X). To determine which component is defective check the PowerON voltage level at CN6704/pin 1. In normal operation 3V should be
measured. If the 3V is present before shut-off then the Power Supply
Board is defective. If 0V is measured before shut-off then the Main
Board is defective.
Finally, there are PFC protection circuits on the Power Supply Board
that when activated will cause a 2X blink protection mode. The PFC
circuit is monitored for both over-voltage and over-temperature.
Therefore, if all the previously discussed circuits checkout okay,
there could still be a problem on the Power Supply Board in the PFC
circuit causing the 2X blink. Replacing the Power Supply Board will
x the TV.
3X Blink- DC Regulator/Audio Error
The Audio error can occur due on of the following error conditions.
If approximately 12Vdc is present and remains below 12Vdc before
shutdown then further troubleshooting is necessary to determine the
defective component.
After conrming proper REG12V levels, check the Negative LED
Backlight supply levels. A loss or excessive condition of the negative
supply will cause a 2X blink failure. The voltage level can be checked
at CN6701/pins 1 & 3 before the TV shuts off. There will be 2 to 4
wires (Red & Blue) depending on the panel size. All individual wires
should be checked for proper voltage level. In normal operation the
voltage level will initially rise to approximately -175V and then should
●Defective DC Regulator on Main Board
●Shorted or Damaged Speaker Connections
●Defective Audio Amplier (Main Board)
●Loss of AU12V (Open F4200 on Main Board)
●Loss of AU12V (Open Fuse on Power Supply Board)
KDL-32EX725/40EX725/55EX72531
Page 38
SECTION 4 - TROUBLESHOOTING
The rst thing to check when a 3X blink protection mode occurs is
the physical condition of the speakers and speaker connections. The
speakers should measure 8 ohms. Shorted speakers or connections
can cause a 3X blink protection mode.
If the speakers and connections check okay, then the defective
component is on the Main Board. Either an open F4200, defective
DC Regulator, or defective Audio amplier will cause a 3X blink
protection mode. In any of these cases, replace the Main Board to
x this condition.
A defect on the Power Supply Board can cause a 3X blink protection
mode and shut-off. Check the AU12V level at CN6704/pin 14. If 0V is
measure before shut-off the Power Supply Board is defective.
4X Blink – Balancer Error
The 4X error code is only used on models incorporating local dimming
LED backlighting. If a failure occurs on the LD board the TV will shut
down and display this diagnostic code. Models using conventional
non-local dimming LED backlighting do not utilize this error code.
5X Blink - T-CON Error
The 5X blink protection mode indicates a communications error
between the T-CON Board and the X-Reality microprocessor on
the Main Board. If the T-CON is available for replacement, replace
the T-CON. If the T-CON is not available, the LCD panel must be
replaced since the T-CON circuit is part of the LCD panel assembly.
In rare cases a loose or defective LVDS cable could also be the
cause.
6X Blink - Backlight System Failure
NOTE: All models will make two attempts to power up before a 6X is
activated. The SONY logo (Backlight) may or may not display on the
screen. However, the splash tones will be heard two times. After the
second attempt the TV will turn off and the standby LED will blink a
6X protection mode. (Note: The splash tone may not be heard if it is
turned off or the volume is set to minimum.)
If a 6X blink pattern is activated then a defect has occurred in one of
the following areas.
●Defective Panel LED(s)
●Defective Power Supply
When troubleshooting a 6X backlight system failure it is key to notice
if the backlights illuminate before the TV shuts off. The following
list shows the possible backlight status and blink pattern and the
possible failed components.
1) Momentary Backlight and 6X
a) Defective LED(s) (LCD Panel Assb.)
2) No Backlight and 6X
a) Replace Power Supply
In most cases, if the Sony logo (Backlight) momentarily illuminates
and the TV shuts off and a 6X is activated than one or more of the
backlight LEDs are defective. The LCD Panel assembly panel must
be replaced for a defective LED. However, before replacing the LCD
panel assembly check for a complete loss of the Negative Backlight
(-89V to -125V) power supply. The -89V to -125V power supply can
be checked at CN6702/pins 1 & 3.
KDL-32EX725/40EX725/55EX72532
Page 39
SECTION 4 - TROUBLESHOOTING
If there is no backlight before the TV shuts off and activates a 6X,
than check the “Backlight ON” signal from the TV microprocessor
and the Positive (+145V) Backlight power supply from the Power
Supply Board. The BL-ON signal can be checked at CN6704/pin 5
and the +145V at CN6701/pins 1 & 3.
If the “Backlight-ON” signal is okay and the Positive Power supply
is missing then the Power Supply Board is defective. However, if
the Backlight-ON is missing then the X-Reality Microprocessor is
defective and the Main Board must be replaced to repair the problem.
7X Blink - Temperature Failure
These models do not display a temperature warning OSD dialogue
box before shutting off and going into a 7X standby LED blink pattern.
The main objective when a 7X blink pattern occurs is to determine
which of the following possible defects is causing the excessive
temperature condition indication.
●Excessive Ambient Room Temperature
●Dust or Debris Blocking the TV Ventilation Apertures
●Defective Temperature Sensor or X-Reality Microprocessor
(Main Board)
If the TV takes a considerable period of time to shut-off check the
following items:
●The TV should not be located too close to any heating
devices.
●The TV should have at least 4 inches of clearance around
the sides & rear, and 11 inches of clearance over the top to
ensure adequate ventilation.
●Check that all vented areas on the TV are clear of all dust
and debris.
●If the TV shuts off immediately after Power-ON then one
of the following components has failed (Not an Actual
Excessive Temperature Condition).
●X-Reality Microprocessor (Main Board)
●Temperature Sensor (Main Board)
In either case the Main Board must be replaced to x the
problem.
The rst step is to notice how long it takes the TV to shut off and
trigger a 7X blink protection mode.
If the TV has an actual excessive temperature condition it will
take a considerable period of time to shut off and indicate a 7X
blink protection mode. This is because it will take time for the TV
components to heat up and for the temperature sensor to detect the
excessive temperature and shut the TV off.

Guidelines for Remote Control
• Point your remote control directly at the
IR sensor located on your TV.
• Make sure that no objects are blocking
the path between the remote control and
the IR sensor on your TV.
• Fluorescent lamps can interfere with
your remote control; try turning off the
fluorescent lamps.
• If you are having problems with the
remote control, reinsert or replace your
batteries and make sure that they are
correctly inserted.
Before setting up your TV
Some TV models are packaged with a
detached Table-Top Stand so you can
mount your TV to a wall right away. If you
are not mounting the TV to a wall, you will
need to attach the Table-Top Stand. You
will need a Phillips screwdriver (not
supplied) or a hexagon wrench (supplied to
some models) and the supplied screws to
complete the task. Look for the supplied
Table-Top Stand instruction leaflet.
Be sure to consider the following while
setting up your TV:
• Disconnect all cables when carrying the
TV.
• Carry the TV with the adequate number
of people; larger size TVs require two or
more people.
• Correct hand placement while carrying
the TV is very important for safety and
to avoid damage.
Getting Started
• Ensure your TV has adequate
ventilation, see page 19.
• For best picture quality, do not expose
the screen to direct illumination or
sunlight.
• Avoid installing the TV in a room with
reflective wall and floor materials.
• Avoid moving the TV from a cold area
to a warm area. Sudden room
temperature changes may cause moisture
condensation. This may cause the TV to
show poor picture and/or poor color.
Should this occur, allow moisture to
evaporate completely before powering
the TV on.
• Ensure that there are no objects in front
of the TV.
• Do not expose the Presence Sensor to
direct sunlight or other strong light, as
malfunction may occur.
