If your Sony Android TV is continuously restarting or, in other words, is stuck in an endless restart cycle, you may have to perform a forced factory reset. The continuous restart problem can occur when the TV software freezes after a firmware update and a standard factory reset cannot be performed. Sometimes a Sony Bravia TV restarts when it needs a firmware update. When an update occurs, the company sends it to all televisions to fix the problems.
Step 2 concludes with operating and updating the TV. Sony recommends not reconnecting the TV to the router at first to avoid experiencing the same problem again and instead wait for technical support to determine the cause of the problem and, therefore, find a solution.
