> disconnect the wireless radio from the main board
Can you explain why you can't just not give the TV your Wi-Fi password?
Or are we worried about the case when the TV did have Wi-Fi (due to it being mandatory for some initial setup, say), but we don't trust that "Forget Network" and "Wi-Fi off" are actually honored?
Suppose the device surreptitiously reconnects to Wi-Fi in spite of being told to forget it. You may be able to block it in your router and failing that, change the access point password.
