SONY - KDL-32BX355_40BX455_46BX455_SERVICE MODE _ SOFTWARE UPDATE DETAILS
SOFTWARE UPDATES & ADJUSTMENTS
The models in
this manual utilize a “generic” type of Main Board, therefore a software update
must be performed and certain service adjustment settings must be changed or
confirmed whenever the Main Board, LCD Panel, or TCON Board is replaced.
There are 2
reasons for updating the software on the TVs.
Software
updates for customers
These updates
are for enhancements or improvements that have been made to the software after
the TV was released.
Software
update for services
These
updates are specifically for services to use during a service call.
SOFTWARE UPDATE FOR CUSTOMERS
The subject
of software updates is 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
- Customer Manual Downloads: Software updates can be performed by the customer by placing it on a USB device 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 device, unzip the file, and the procedures for loading the software into the television.
- 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 with this type of chassis 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 TV without any input from the customer.
SOFTWARE UPDATES FOR SERVICES
- Replacement Main Boards are now stocked with basic software. Once the replacement board is installed in the TV, the most current software needs to be installed using a USB device containing the necessary software.
- This new method of supplying Main Boards significantly reduces the complexity of replacing the 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 can be replaced more efficiently.
