There is no antenna connected. As to service menu, due to the number of folk that brick their set and incur a big service or repair bill, no moderator I know will write anything but no, stay out of the service menu.
I have a Samsung smart TV, 8 Series. I am unable to access the Broadcast option in settings - grayed out. I have learned that to fix this i might have to access the Service Menu, but the examples of how to access the service menu use a different remote than I have. My 'smart' remote has no numeric keypad, and no mute, info, or menu buttons. Is there a way to access the service menu with this remote/ Or - basic question - how to ungray the broadcast option?
