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.
