LCD Digital Color TV_SOFTWARE UPDATE AND OTHER DETAILS {AZ2-F Chassis Segment: 3a-2}
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 Centre and it is deemed to be
correctable with a software update, the issue is handled at the customer level.
SOFTWARE UPDATES FOR SERVICE PERSONAL
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 T-CON 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 T-CON 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.
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 service will be notified and receive the proper authorization
for reimbursement.
