    How to restart (reset) an Android TV?
  2. If peripheral devices are connected to the TV, remove them.
  3. Turn off the power supply of the TV and pull out the power cord (mains lead) from the outlet.
    Wait approximately 2 minutes, and then insert the power cord in the outlet again and turn on the power supply of the TV.
    NOTE:
    • If you connect your BRAVIA TV to an external HDD, remove it and try again.
    • If you leave the TV with the power cord (mains lead) disconnected, the electricity that remains in the unit will be discharged.
      As a result, unnecessary data and error information in the memory will return to their defaults, and allow you to use the TV again normally.

  4. When the screen becomes black or the image is not displayed correctly in the HDMI/MHL connection, try the following methods to improve it.
    NOTE: Your TV may not be compatible with a MHL connection. For details on your TV's specifications, refer to the manual.
    • Disconnect and connect the HDMI/MHL cable.
    • Disconnect and connect the power cord (mains lead) of the connected device or reboot the device.


  5. If you experience an abnormal image or sound, reset the picture or sound settings.

    • Picture setting:
      HOME > Settings > TV - Display > Picture > Advanced settings > Reset
    • Sound setting:
      HOME > Settings > TV - Sound > Sound > Advanced settings > Reset

  6. Software Update is an update program that adds new features and fixes bugs.

    We recommend that you connect the BRAVIA TV to the Internet, and set Automatic Software Download to On. Updates will automatically be downloaded when the TV is in Standby.
