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.
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
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 device 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 device, 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.
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 device 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.
