I have 4 LG 86UK6570PUB Smart TVs and I have been able to get to the Service Menu, but a lot of the options do not allow me to modify them, including whether or not the wifi is on. Does anyone know what I am doing wrong or have a suggestion how I could get this to work? I just want to disable Wifi Direct and Wireless as we are going to use a different method of screen sharing.
