I was bored a few months ago and opened up my samsung tv to see if I could unhook the wifi antennas. Turns out there wasn't actually any in there but I was able to desolder the wifi chip. It was a small separate board mounted by 8 or so pins off the motherboard that I had to use low temp solder on.
TV still works (minus the streaming services). If you try to open the network settings the screen just shows a loading icon indefinitely.
