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.
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 
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.

SECTION 5 - UPDATES AND ADJUSTMENTS
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 
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.
