I have a samsung "smart" TV, and a few years back it started interrupting the DVD I was trying to watch every 15 minutes or so to tell me to check my internet connection. My internet was fine, but whatever server it was phoning home to had apparently gone down.
I ended up factory resetting the TV to make it forget my wifi credentials, and I just haven't put it back online since then. I haven't regretted it at all.
I think mine is compatible with the SammyGo custom firmware, so I might install that one of these days, and then maybe I'll reconnect it to my network. But, for now, I just have a PC connected to it and manage everything there.
