Has anyone found a way to turn off the wireless and bluetooth functions on Samsung Smart TV's? I have a NU7400 and was disappointed to see no option for this in the settings menu. Selecting and using the wired network does not seem to stop the wifi board transmitting and there is no control over bluetooth at all. I wrongly assumed it would be possible to turn them off just like you can on a mobile phone. I just want to use a wired network connection as exposure to wifi and/or bluetooth within a few metres of the source gives me headaches.
