I asked this question a year ago, and was advised to buy a TV and never connect it to my network. That worked fine for me… But, one person told me they bought a TV that would not function until it was connected to their network to run “updates” so he took it back to the store and got a replacement. The replacement did the same thing so he took that back too. (I think he eventually got one that just “worked” out of the box without requiring an update just to work.
