Updates and 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.
These updates are accessed by the customer from the Sony Support Site at http://esupport.sony.com.
Software update for service technicians
These updates are specifically for servicers to use during a service call and are only available on the Sony Authorized Servicer Portal.

Software updates 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 accessed by the customer from the Sony Support Site at http://esupport.sony.com where they can be downloaded and placed 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.

Software updates for service technicians
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 thumb drive 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. The software update and procedures for the software installation are located on the Sony Authorized Service Portal.
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.

Examples of software correctable symptoms
Always check the Sony Authorized Servicer Portal for any known and/or listed issues that are software related. 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 (internet models only)
* Certain features not working correctly (photo or video file viewing)
