OVERVIEW
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 a 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.

SECTION 2 - SOFTWARE REQUIREMENTS
SOFTWARE UPDATES FOR SERVICERS
The  models  in  this  manual  utilize  a  generic”  type  Main  Board.  In 
the past, many different Main Boards needed to be stocked due to 
differences  in  software  requirements. The  software  loaded  on  the 
board was specific to the model and its features along with the type 
of LCD panel installed during production. 
Replacement  Main  Boards  are  now  stocked  with  basic  software. 
Once the replacement board is installed in the unit, the most current 
software needs to be installed using a USB thumb drive containing 
the necessary software downloaded.
This new method of supplying Main Boards significantly reduces the 
complexity of replacing LCD panels and 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 or LCD panel can be replaced more efficiently.
In  addition  to  software  installation,  service  adjustment  information 
may need to be modified or verified to complete the service of the 
TV. Service adjustment information is covered in 
“Section 7 - Service 
Adjustments” on page 48.
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.
