SECTION 2 - SOFTWARE REQUIREMENTS
SOFTWARE UPDATES FOR SERVICERS
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.
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
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.
