Network Downloads: Internet software updates are
becoming more prevalent as more and more models
incorporate home network capabilities. This method is the
most practical since the television will check for the latest
version of software. The models using the this wchassis
provide the customer with a choice of turning the automatic
software update feature on or off. If set to on, the television
will lookup software information while the unit is in standby.
If a newer version is available, it will be downloaded and
installed without any input from the customer.
●
Built-in Tuner: OTA or cable sources having the proper
station that is transmitting software update data packets.
Although the ability to transmit software update is possible in
this way, it is the least common and is reserved for particular
situations where a critical update is "forced", thereby
updating the unit without any input from the customer.

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. The software update and procedures for the software
installation are located on the Sony Authorized Servicer Portal at
http://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
