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.
