SEC 1. SOFTWARE REQUIREMENTS

1-1. OVERVIEW

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. The software
update and procedures for the software installation are located on
the Sony Authorized Servicer Portal at www.sony.com/asp.
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
Adjustments on page 20.

1-2. SOFTWARE UPDATES

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.
Software updates can be performed by:
Sec 3. Service
• Customer Manual Downloads: Software updates can be
accessed by the customer from the Sony Support Site at

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.
