If they’re using bluetooth and wifi, we better find and remove those components too.

Removing the Bluetooth/wifi module maybe more difficult. For cost cutting reasons, these controllers are built into the logic boards now, but disconnecting the bluetooth/wifi antennas inside the TV is trivially easy. They are simple push-on mechanical connectors. No wire cutting needed. Gently grab the gold/silver metal part pull straight up from the board.

I just googled “lcd TV logic board” and this was one of the first images I found. I put a red square around the antenna connectors.
