CAUTIONS AND WARNINGS
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”.
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.
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)

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 10 provides an overview of the AZ3G
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 analog/digital unit. It can receive traditional
analog NTSC signals via cable or terrestrial along with digital SBTVD.
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.
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 amplier for processing and
amplication.
HDMI Input and Switching: The customer can select from the HDMI1
through 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
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 amplier (IC4601) and sub-woofer amplier
(IC4701) amplies 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
The Power Supply Boards used in this model are:
●G14 and G15 Boards
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 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.
3D IR EMITTER BOARD
Designated as the HEM3 Board, this board is the internal 3D IR Emitter to
synchronize the 3D shutter glasses.

XBR-65HX955 5
SECTION 1 - FEATURES AND OVERVIEW
WIRELESS LAN CARD
The wireless transmit/receive circuits are located on this board to
communicate with a wireless network.
SWITCH UNIT
This board contains the power, channel and volume up/down, and menu
buttons.
LCD PANEL ASSEMBLY
The LCD Panel Assembly includes the LCD Panel, TCON Board and LED
Backlight system.
NOTE: The LD Board is not always included with the LCD Panel. Check
with the LCD Panel manual for the most update information regarding this
information.
The LCD Panel contains the actual liquid crystals, color lters and
polarizers. The liquid crystals are manipulated by the applied voltage to
pass a specic amount of light - from the backlight- 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
●LED Backlighting System (varies)
●TCON Board
●LD Board
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.

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.
Most symptoms that are correctable by software updates involve
communications issues with other devices or minor glitches in the operation
of a specic 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)
SECTION 2 - TROUBLESHOOTING
Self Diagnosis
Supported model
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.

VIEWING THE SELF CHECK DIAGNOSIS HISTORY
When an error is detected, the Self Check screen records the date(s) and
the number of times the error occurred. This is helpful in conrming past
occurrences of an error and for determining if an error is intermittent when
the customer is not sure what is causing the television to shut down. If the
screen displays a “0”, no error has occurred.
1. Take the TV out of deep Standby mode by pressing
POWER
to
turn on the TV.
2. Press

SAMPLE SELF CHECK DIAGNOSIS PAGE

XBR-65HX955 8
SECTION 2 - TROUBLESHOOTING
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/HDMI/Tuner
Several items are monitored on the Main Board. Any error detected in the
following circuits will cause the television to shut down and generate a 3X
error:
●Loss of regulated B+ circuits
●Audio amplier failure
●HDMI equalizer IC
●Tuner demodulator circuits
In most cases, replacement of the Main Board will remedy a 3X error.
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 or one of the LED’s fails in
the panel 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 - TCON Error
The 5X blink protection mode indicates a communications error between
the TCON Board and the X-Reality microprocessor on the Main Board. If
the TCON is available for replacement, replace the TCON. If the TCON is
not available, the LCD Panel must be replaced since the TCON circuit is
part of the LCD Panel Assembly. In rare cases a loose or defective LVDS
Cable could also be the cause.
6X Blink - Converter System Failure
If the Converter circuit (located on the power supply or separate Converter
Board) fails to start or shuts down due to an over-voltage or over-
current condition, the unit will shut down and generate a 6X error code.
The diagnostic page labels this as a “Backlight Failure” even though the
backlights are not a source of the problem. Replacement of the Power
Supply Board should rectify this problem.
7X Blink - Temperature Failure
If the temperature inside the television becomes excessive, the temperature
sensor (located on the Main Board) noties the TV to shut down and display
a 7X error. Excessive temperature errors will always occur when the TV
has been running a while and can be caused by excessive ambient heat or
improper ventilation of the television.
8X Blink – Not listed in Self Check
The 8X blink code is mainly used during TV software development. Look in
TV’s service Self Check for error code history and notice at the bottom of
the list WDT (Watch Dog Timer) error codes, in particular notice 103 HOST_
WDT. If this error code appears, check for any additional documentation on
the Sony ESI site.
10X Blink – IR Sync Transmitter Failure
A failure of the infrared sync transmitter circuits on the HEM3 Board will
cause a 10X error and replacement of this Board will usually rectify the
problem. In rare cases, the Main Board could be the source of the failure.
