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
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)
KDL-32EX650/32EX651/40EX650/40EX651/46EX650/46EX651 vi
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.

“Block Diagram” on page 10 provides an overview of the AZ3F
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 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.
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.
HDMI Input and Switching: The customer can select the HDMI1,
HDMI2, HDMI3, 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 noisefree 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 amplier (IC4601) and sub-woofer amplier
(IC4701) 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.
POWER SUPPLY BOARD
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:
●GL2 Board (for 32” models)
●GL4 Board (for 40” and 46” 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 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.
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.
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 backlite - 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 from parts will include the following items.
●LCD Panel
●TCON Board
●LED Backlighting Components (varies)
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.
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 site 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
●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.
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 conrming 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.
