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. 

These updates are accessed by the customer from the Sony 

Support Site at 

http://esupport.sony.com

.

•  Software update for servicers

 

These updates are specifically for servicers to use during a 

service call and are only available on the Sony Authorized 

Servicer Portal at 

http://www.sony.com/asp.

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.
Software updates can be performed by:

•  Customer Manual Downloads: Software updates can be 

accessed by the customer from the Sony Support Site at 

http://esupport.sony.com

 where they 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.

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.  The  software  update  and  procedures  for  the  software 

installation are located on the Sony Authorized Servicer Portal at  

http://www.sony.com/asp.

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 

Updating the Software 

on page 43.

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 

TV requiring a legitimate service is running the latest software 
version and to install it if necessary.

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.
