If a full reset (restart) of the TV is required

If you have trouble such as the picture not displaying on the screen or the remote control not working, reset the TV with the following procedure. If the problem persists, try the factory reset procedure below.
If an external USB device is connected to the TV, disconnect the USB device from the TV before resetting.

Power Reset

  1. Restart the TV with the remote control.
    Press and continue holding the power button on the remote control for about 5 seconds until the TV restarts (a shutting down message will appear). (Depending on your model/region/country, you can also press and hold the power button on the remote control for about 2 seconds and then select [Restart] from the TV screen.)
    The TV will turn off and restart automatically after about one minute.
    If the TV does not turn on automatically, press the power button on the remote control after 20 seconds.
  2. Unplug the AC power cord (mains lead).
    If the problem persists after step 1, unplug the TV power cord (mains lead) from the electrical outlet. Then press the power button on the TV, and release it. Wait for 2 minutes, and plug the power cord (mains lead) back into the electrical outlet.

Hint

  • TV models with 1 button on the TV (power button only) can also be restarted using the power button. Press the power button on the TV to display the operation menu, select [Restart] in the menu, and then press and hold the power button to restart the TV.
  • Your personal settings and data will not be lost after the TV restarts.

Factory data reset

If the problem persists after a power reset, try a factory data reset.

Note

Performing a factory reset will delete all of the TV’s data and settings (such as Wi-Fi and wired network setting information, Google Account and other login information, Google Play and other installed apps).

  1. Press the (Quick Settings) button on the remote control, then select [Settings] — [System] — [About] — [Reset] — [Factory data reset].
  2. Delete everything.
    If you have set a PIN code on your TV, you will be prompted to input it.
    After the factory reset process completes successfully, the TV will start the Initial Setup wizard. You must agree to the Google Terms of Service and Google Privacy Policy.
