There are 2 reasons for updating the software on the TVs:

Software update for servicers
These updates are specifically for servicers to use during a service
call.
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
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
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 downloaded and placed on a USB thumb
drive to be loaded onto the TV. The instructions for downloading
the software file 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 file and the
procedures for loading the software into the television.
●
Network Downloads
Internet software updates are becoming more prevalent as more
and more models incorporate home network capabilities. This
method is the most practical since the television will check for the
latest version of software. The models with this type of chassis
provide the customer with a choice of turning the automatic
software update feature on or off. If set to on, the television will
lookup software information while the unit is in standby. If a newer
version is available, it will be downloaded and installed without any
input from the customer.
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 significantly reduces the
This new method of supplying Main Boards significantly 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 efficiently.

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 notified and receive the proper authorization
for reimbursement.
It is the servicer’s responsibility, however, to
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.
