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 in “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.
Follow the manufacturers’ instructions provided with the tester.
2. A battery-operated AC milliammeter.
LEAKAGE TEST
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. Nearly all
battery-operated digital multimeters that have a 2 VAC range are
suitable. (see Figure A)
Figure A. Use an AC voltmeter to check AC leakage.
HOW TO FIND A GOOD EARTH GROUND
The cover-plate retaining screw on most AC outlet boxes is at earth ground.
Verify the AC outlet box retaining screw ground by connecting a 60W to
100W incandescent (not a neon or uorescent 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)

SECTION 1 - FEATURES AND OVERVIEW
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
A/D converted and scaled (if necessary) to 1920 X 1080p 60HZ resolution.
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.
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 amplier provides the drive for the speakers.
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.
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
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,
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 Audio 12V.
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.

SECTION 1 - FEATURES AND OVERVIEW
LCD PANEL ASSEMBLY
The LCD Panel Assembly includes the LCD Panel, TCON Board and LED
Backlight system.
The LCD Panel contains the actual liquid crystals, color lters and polarizers.
The liquid crystals are manipulated by the applied voltage to pass a specic
amount of light - from the backlit - depending on the level of voltage applied.
The TCON performs all the control, timing, charge and discharge functions
driving the operation of the LCD Panel.
A new LCD Panel Assembly will include the following items:
● LCD Panel
● Bezel Assembly (includes H Board)
● TCON Board
● LED Backlight system
TCON BOARD
The TCON Board communicates between the LCD Panel and the
microprocessor on the Main Board.
NOTE: The TCON Board is not available as a replacement part for all
models. To determine if the TCON Board is available as a replacement
part, refer to the LCD Panels Manual.

SECTION 2 - TROUBLESHOOTING
Self Diagnosis
Supported model
OVERVIEW
This chapter provides information regarding the Self Diagnosis feature in
our TVs.
UPDATING THE SOFTWARE
The Self Diagnosis function is designed to provide information regarding
the problem with the TV, however, there are several issues that may be
resolved by updating the TV software to the latest version. Always check
the Sony Authorized Servicer Portal at http://www.sony.com/asp for any
issues that are software related. 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
● TV turns on and off by itself
● Loss of color
● Internet connectivity (internet models only)
● Certain features not working correctly
(photo or video le viewing)
SELF DIAGNOSIS FUNCTION
Critical voltages and circuit operations are monitored by the CPU on the
Main Board. If an error is detected the Self Diagnosis function in the TV will
force the TV to shut down by the CPU. The monitored circuit in which the
fault occurred will automatically cause the CPU to blink the Standby LED
in groups of repeating sequences. The number of times the Standby LED
blinks indicates the possible cause of the problem.
Not all of the available protect codes are used in every model. For example,
models that don’t have the local dimming feature do not use the 4X blink
error as this circuit is found in models that are backlit with uorescent lamps.
The information in this section provides guidance in locating the possible
component causing the shutdown.

SAMPLE SELF CHECK DIAGNOSIS PAGE
2X Blink - Main Power Error
A loss of REG12V from the power supply triggers this protect event. The
usual cause is a failure of the main switching supply. In some instances,
excessive loading on the secondary supply lines can cause the switching
regulator to stop, or fail again, if a replacement board is installed.
3X Blink- DC Regulator/Audio Error
The REG 5V and D3.3V source originating on the Main Board is monitored
for low-voltage conditions by the CPU. A failure causing a 3X shutdown
requires replacing the Main Board.
4X Blink – Balancer Error
NOT USED IN THIS MODEL SERIES.
5X Blink - TCON Error/Panel Error
The 5X blink protection mode indicates a communications error with the
timing control circuits (TCON Board) has occurred. If the TCON Board is
available for replacement, replace it, if not, replace the LCD Panel Assembly.
In rare cases a loose or defective LVDS cable could also be the cause.

6X Blink - Backlight Converter System Failure
If the converter circuits fails to generate high voltage or one or more of
the backlight fails to light, the television will shut down and display this
diagnostics error.
7X Blink - Temperature Failure
A digital thermometer IC located on the Main Board provides a temperature
reading of the chassis and LCD Panel. If the temperature exceeds a predetermined point the TV will shut down. If this problem occurs immediately
at turn-on, the temperature sensing IC has failed and replacing the Main
Board is required. If this occurs after the TV has been running for a while,
check for ventilation issues that could cause the TV to run hotter than
normal.

SECTION 5 - UPDATES AND ADJUSTMENTS
OVERVIEW
The models in this manual utilize a “generic” type of Main Board, therefore a
software update must be performed and certain service adjustment settings
must be changed or conrmed whenever the Main Board, LCD Panel or
TCON Board is replaced.
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.
These updates are accessed by the customer from the Sony
Support Site at http://esupport.sony.com.
● Software update for servicers
These updates are specically for servicers to use during a
service call and are only available on the Sony Authorized
Servicer Portal at http://www.sony.com/asp.
SOFTWARE UPDATES FOR CUSTOMERS
The subject of software updates is 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.
Software updates can be performed by:
● Customer Manual Downloads
Software updates can be accessed by the customer from the
Sony Support Site at http://esupport.sony.com where they
can be downloaded and placed on a USB thumb drive to
be loaded onto the TV. The instructions for downloading the
software le vary from chassis to chassis and sometimes from
model to model. The customer is provided with the instructions
to properly format the USB thumb drive, unzip the le, and the
procedures for loading the software into the television.
SOFTWARE UPDATES FOR SERVICERS
Replacement Main Boards are now stocked with basic software. Once the
replacement board is installed in the TV, the most current software needs
to be installed using a USB thumb drive containing the necessary software.
This new method of supplying Main Boards signicantly reduces the
complexity of replacing the Main Boards. Information about the LCD
panel is stored on the TCON 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 TCON can be replaced
more efciently. The software update and procedures for the software
installation are located on the Sony Authorized Servicer Portal at
http://www.sony.com/asp.

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.
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.
EXAMPLES OF SOFTWARE CORRECTABLE SYMPTOMS
Always check the Sony Authorized Servicer Portal at www.sony.com/asp
site for any known and/or listed issues that are software related. 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 (internet models only)
● Certain features not working correctly
(photo or video le viewing)
