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 servicers

 

These updates are specifically for servicers to use during a 

service call.

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 using a USB device. The 

instructions for downloading the software file vary from 

chassis to chassis and sometimes from model to model.

● 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 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 unit without any input from the customer.

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  latest 

software update must be installed after replacing the Main Board.
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 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 

TV requiring a legitimate service is running the latest software 
version and to install it if necessary.

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.

Most symptoms that are correctable by software updates involve 

communications issues with other devices or minor glitches in 

the operation of a specific function. Below is a list of some of the 

symptoms that may be corrected with a software update:

 

● Fluctuations in picture brightness

 

● Intermittent picture freezing or noise

 

● Problems with certain inputs (especially HDMI)

 

● Intermittent or distorted audio

 

● Erratic remote control operation

 

● Unit turns on and off by itself

 

● Loss of color

 

● Internet connectivity

 

● Certain features not working correctly
