I have a smart TV from the brand ok the first few days were great but now he can't connect to the Internet anymore and if I want to YouTube or Netflix is not connected although actually my TV is connected to the Wi-Fi now I wanted to ask you know how to reset the TV
Now he is not ok anymore.
Joking aside. Plug it out for half an hour and then test again. For security in the settings / network, see if he really connects.
