Documented Service Records – All Level Technicians.
Power Faults - Display Faults - Memory Errors
The following information in this SONY case history e-book was written
and compiled according to Damon Morrow's in-house service records (or
case history) of SONY LED & LCD TV failures. This e-book documents a
descent range of SONY LED & LCD TV faults including various memory
error's, display symptoms, and power failures. This SONY case history ebook is very easy to use, and it simply lists a fair range of popular problems
and secretive fixes for SONY LED & LCD TV's. The information contained
in these pages are complete with the model number of the SONY LED &
LCD TV, the board-number of the faulty circuit, and the part-location
number of the defective component(s).
This SONY e-book is a simple and affective reference tool, revealing
components which have failed causing performance issues with SONY LED
& LCD TV's. This e-book documents known symptoms on SONY LED &
LCD TV's such as Stand-by power only, dead-no power, no start-up cycle,
double image on-screen, no audio, and much more. The components and
IC's which have failed are listed in this e-book, and they are mainly standard
parts and IC's. Standard parts such as diodes, resistors, mosfet's, NPN's,
capacitors, and IC's such as memory IC's, control IC's, and bucking IC's. The
test equipment used while compiling this SONY case history information
was a standard DVM meter (Fluke), Capacitor meter (uF/ESR) and a 60Mhz
digital Oscilloscope (the very basics all technicians use).
The scope was primarily used to troubleshoot IC chips and observe their
wave shaping performance, feedback-loops, start-pulses, duty-cycles, serialclock, and gate-circuits. However, in this e-book all of the troubleshooting
has been done for you, with the causes and bad parts listed.
This SONY e-book is for technicians of all levels, there are no complex
diagrams or detailed graphics involved. This e-book is not a case history of
troubleshooting and circuit evaluation (as with my other books). This e-book
is a simple case history of SONY LED & LCD TV parts failure. Again, all of
the troubleshooting work has been done for you and compiled in a simple
and easy to follow format. This e-book is written text information
correlating to shop records. There are no pictorial graphics or illustrative
diagrams used in this e-book as it is not required i.e. 'case-history'.

The following are basic protocols used when servicing SONY LED & LCD
TV's.
Quick Tips On SONY T-Con Flash/EEPROM's
Quick Emphasis on SONY T-Con EEPROM Faults & Firmware upgrading
With-in the professional TV repair industry, Sony LED/LCD TV's have been
known to develop flash memory or EEPROM problems, primarily on the TCon board. This memory problem on the T-Con board produces a small
range of display symptoms on the panel. This e-book documents secretive
case histories for a variety SONY T-Con memory issues resulting in a
display fault symptom (as well as all other Sony faults). Throughout the case
history section of this e-book you will find many T-Con solutions to known
display problems on various Sony TV models, therefore the following
information is very important to take note when servicing Sony T-Con
boards or when replacing Sony T-Con boards.
Software/Firmware upgrades are usually required on some Sony TV models
when replacing Flash/EEPROM IC chips on Sony T-Con boards or replacing
the entire T-Con board, (software/firmware upgrades are model specific).
Go to the following link for the SONY T-Con software/firmware upgrade
website: https://esupport.sony.com
In the case history section of this book you will sometimes see (Go to Sony
Support), this means go to the support link above to upgrade the T-Con
board or Main-Board.
IMPORTANT T-CON NOTE:
Use the following key-commands when servicing the memory section of
Sony T-con boards or replacing the entire T-Con board. Not all Sony T-Con's
need upgrading after repair or replacement, but a fair number of them do
require upgrades. After servicing or replacing the T-Con board (assuming the
T-con is the correct culprit) the TV should not show an error code anymore
(which is good) and if there's still no picture image on the screen......perform
the following procedure to reset the core processor on the main-board which
will be echoed by the micro-controller on the T-Con board. Both the coreprocessor and micro-controller will reset their own individual
Flash/EEPROM when you use the following sequence.

Press the power button on TV. Using the remote control, hold down the UpArrow key and simultaneously press the power button on the TV. The TV
will turn off, then turn back on again, after which let go of the Up-Arrow
key on the remote control. The TV will now perform in its normal function.
Note, that all fields are automatically reset to factory formatted default after
the above procedure is done.

Micro-wire EEPROM #3
In LCD TV technology micro-wire is much older than SPI or I2C EEPROM
interfaces. This IC has two data pin-outs data-in (DI), data-out (DO), clock
input (CLK) and a featured chip-select (CS) (NU= not-used). For memory
configuration this chip has an ORG feature that determines if the format of
data is 16 bits or 8 bits. Micro-wire EEPROM's had a few 'in-circuit'
programming issues that caused T-Cons to fail quite often. This is because in
order for the Timing IC chip to read from the EEPROM, the Timing IC chip
writes a 'read' instruction to 'DI' which is followed up by the 'read' address.
When the EEPROM receives the last address bit, a dummy '0' is written to
'DO' then the data request is written on the CLK's rising edge. This causes
confusion or an unwanted interruption with the 'BUS-read' operations. This
is because when the EEPROM puts out a dummy '0' when receiving the last
address bit, the Timing IC must pull both the 'DO' & 'DI' lines to a logichigh but it cannot do this because the address bit is 1. No amount of
firmware upgrade could permanently fix this problem.
SPI EEPROM #2
The second EEPROM interface to arrive on the LCD TV scene was the SPI
(serial Peripheral Interface) EEPROM. This chip has two lines for data
(SO/SI), clock (SCK), chip-select (CS) and ground. This chip has two other
inputs, and that is the write-protect (WP) which allows the code inside the
EEPROM to be unchanged 'logic-low', write-protect must be 'logic-high' in
order to be programmed. The (HOLD) input feature allows the Timing IC to
stop during transferring states in order to perform a more important task on
the link of the SPI which can only happen at a 'logic-low'.
One known problem with this EEPROM is that it will ignore all BUS
activity until 'HOLD' returns to a 'logic-high' and many times this SPI
EEPROM will remain stuck at 'logic-low' which means a permanent HOLD
on its operation. This causes the T-Con to shut down.
ImagineX ElectronicS
9
I2C EEPROM #1
I2C means (Inter-Integrated Circuit Bus) which is the latest form of Flash
memory being used today in many SONY LED & LCD TV T-Con boards
and main boards (and other LCD/LED TV brands also). This Flash device
has a bidirectional serial-data-address line (SDA) which is where most of the
failure happens on this kind of Flash memory because it requires an opendrain or open-collector output and the Timing IC sends a slave address on
the SDA line. An open-collector/drain means any output that’s a logic-low
will also pull the SDA at a logic-low also.
The SDA is not always released back to a logic-high because a 1 is not
always written to the Flash memories output. When this happens the Timing
IC knows something is wrong and will shut down the T-Con operation, thus
meaning the TV go's onto protect mode. These particular Flash memory
devices usually have an SDA or SCL fault. Of course there are other reasons
why Flash/EEPROM's fail.
ImagineX ElectronicS
10
Why Flash/EEPROM's Fail
Note: If critical signals such as the clock signal and data-address signal are
not sustaining upon TV start up, this is a Flash/EEprom problem.
Flash/EEPROM's usually fail at the data address pins or the serial-clock pin,
but these devices also fail internally in two different ways, which affects the
EEPROM's overall functionality. The two ways in which EEPROM's fail
internally has to do with Stamina and Data- Retention.
ImagineX ElectronicS
11
Stamina:
It all comes down to what the EEPROM can endure while conducting
'write/rewrite' transactions. During these transactions of 'write/rewrite' stages
the gate oxide in the floating-gate transistors of the memory cell will
eventually collect trapped electrons. There's an electric field related to the
trapped electrons, and the electric field joins with the desired electrons in the
floating gate.
All of this results in a memory stage cycle where there are no electrons
available in the floating gate (zero-state), but the gate-oxide still has a leftover electric field. When this condition rises (because of more electrons
getting trapped) a faulty situation will occur in which it is no longer possible
for the Flash/EEPROM to distinguish between the threshold for the 'zerostate'. As a result, the memory cell is stuck in the 'program-state'. This is the
reason why Flash/EEPROM manufacturer's will specify the amount of
'write/rewrite' cycles the Flash/EEPROM can handle (5 million read/write
cycles or more). This is what causes T-Con's and main boards to shut down,
when the Flash/EEPROM gets stuck in 'program-state'......
Data-Retention:
Data-Retention time is critical for Flash/EEPROM's which house software
that's required for the proper functionality of the T-Con board (this also
holds true for the main board as well). The Data-Retention time period is
limited in its ability to store data indefinitely. This is largely due to the fact
that during storage, the electrons that are directed into the floating gate can
drift straight through the insulator especially at high thermal temperatures.
This results in the charge being stored at the floating gate to become
discharged, and when this happens the memory cell will default back to its
'erase-state'. This will cause the Timing IC to shut down all operations on the
T-Con because the Flash/EEPROM is in a constant 'erase-stage'.

Final NOTE:
Be sure to check the value of the base/gate resistors before replacing the
transistor or FET, otherwise there's no sense in installing a BJT or FET
which have damaged Base or Gate resistors because either transistor or FET
will not turn on.

SONY LED & LCD TV Main Board Firmware Upgrade
The following are the necessary steps to upgrade various models of SONY
main-boards. You will need a flash drive, like the one shown in the photo
below which I have used for years.
Use the flash drive to plug in the USB port of the SONY LED/LCD TV. See
the example from the photo below
To acquire firmware/software upgrade go to SONY support link here:
https://esupport.sony.com
ImagineX ElectronicS
18
Update Procedure:
It is important to download the proper firmware/software for the SONY TV model
your servicing.
Instructions: For Main-Board and T-Con Board Firmware Upgrading
1) Plug flash drive into USB port of PC as shown above, then go to the SONY support
link above
2) Configure or format the flash drive to FAT-32 (not NTFS)
3) Download SONY firmware to the flash drive (extract file/folder)
Note that the firmware requires the folder to be extracted too the flash drive along
with the file inside the folder. Do not extract the bin-file only.
4) Turn TV off, and insert the flash drive into the USB port of SONY TV.
5) Plug in AC cord of TV for power and wait a few seconds.
Note if the TV remains on stand-by only, press the power button on TV. If the standby light indicator switches from amber to green allow the TV to run the update
process. Allow 15 minutes for the update process to complete, the TV will cycle
several reboots during the update process. If the update is successful the light
indicator will switch from amber to red.
6) When update process is complete the TV screen will message you to remove the flash
drive from the USB port.
Note if the update is unsuccessful, remove AC cord from outlet, then remove the
flash drive and start the procedure over again from #1. Be sure flash drive contacts
and USB ports are clean.
SONY LED & LCD TV Main Board Firmware Upgrade
NOTE: After a successful update process the TV may appear to function in a slow, and
delayed manner. This happens when the new firmware/software is being configured
and initialized by the micro-controllers on the main-board and T-Con board. The TV
will resume normal response time and operating speed once the firmware/software are
completely configured by the main-board and T-con board.
