The Sony Bravia is relatively easy to reset using either a power cycle method or a factory reset that returns the TV to the original default settings. Factory reset a Sony Bravia when you are reselling the TV or giving it to another person. The full reset removes saved passwords and deletes apps and other aftermarket add-ons. A power cycle is better for minor fixes such as freezing, slow functionality from having too many apps open, or something else bogging down the system. If the Sony TV won't turn on properly or is having a major problem, a factory reset may resolve the issue with a clean slate.
Turn off the TV with the remote or on the TV itself. Remove the power cord and wait for a full minute to drain any residual power. Wait longer if you want as long as you ensure the TV is cut off from power completely. Plug the television back into the power source. Plug it directly into a wall outlet to bypass a potentially bad surge protector. Test the TV to see if your problems are resolved. If not, move on to the factory reset process. Reboot a Sony Bravia primarily to fix minor, intermittent issues.
The Sony Bravia runs on the Android system. To run a factory reset, select the "Home" button on your remote. Select "Settings" followed by "Storage & Reset," "Factory data reset," "Erase everything" and lastly, "Yes." This process is called a data reset, and it erases your entire history and stored data while returning everything to the default settings.

You can also perform a forced factory reset that removes all apps and everything in the TV memory relating to you and your history. To do this, unplug the TV. Hold down the "Power" and "Down" buttons at the same time and plug the power back into the outlet while holding the buttons for 30 seconds. When a green LED light comes on, release the buttons. Wait while the TV reboots multiple times and runs through the reset cycle. The original Welcome screen appears when the process is complete.
Updates and Troubleshooting
Outside of the reset process, your TV will require occasional updates. The Sony Bravia TV update 2017 was an important one to run. Failing to stay current on updates can lead to problems. Additionally, troubleshoot issues with individual apps before assuming the TV is having a problem. In some cases, deleting and reinstalling the application responsible for freezing or other failures resolves the problem.
