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 confirmed 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.
●
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
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 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.
●
Built-in Tuner
OTA or cable sources having the proper station that is
transmitting software update data packets. Although the ability
to transmit software update is possible in this way, it is the
least common and is reserved for particular situations where
a critical update is "forced", thereby updating the TV without
any input from the customer.
