Se vc só tem o smart controle e não tem acesso ao menu da tv, esse processo funcionou para mim:
- Turn on the TV.
- Hold down the power button on the TV itself for 5 seconds.
- Then immediately after, hold down the remote’s power button for 5 seconds.
- The TV will be off for about 30 seconds and then turn on.
- The TV will enter installation mode. Now unplug the power cable from the TV for 30 seconds.
