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 

.

 

● 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 

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 

accessed by the customer from the Sony Support Site at 

 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.
