Factory reset on Sony Bravia TV displays

Without remote control

1. Unplug the TV from the power outlet.
2. Press and hold the button in the center at the bottom of the display (usually under the Sony logo).
3. Plug the TV into power and keep holding the button for at least 20 seconds. The LED below the Sony logo will start blinking (if there is one). Otherwise proceed to step 4.
4. The Android logo will appear and the TV will reset to factory settings.

With remote control

Go to Settings > System > About > Reset > Factory Data Reset.

Warning:

Select Factory Data Reset and not Erase data from …, as “Erase data from” will cause an error during ZTP.
