    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.

    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
