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 an external USB device is connected to the TV, disconnect the USB device from the TV before resetting.
- Restart the TV with the remote control.
Press and hold the power button on the remote control and select [Restart]. The TV will turn off and then restart after about one minute.
- 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 and wait for 2 minutes. Then plug the power cord (mains lead) back into the electrical outlet.
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.
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).
- Press the HOME button, then select [Settings] — [Device Preferences] — [About] — [Reset].
- Select [Reset].
