Note that the LG takes regular screenshots, uploads them to their servers, and sells them. If you don't allow it on the internet, it saves the screenshots to internal storage and uploads once it is connected. If you don't attach it to the internet, or give it permission to upload them, and later sell the screen to someone who does do that, all your data is uploaded then.

I would not resell a LG tv that has been used for anything but content consumption.
