I have a UN70NU6900 Samsung TV. Up to like a couple weeks ago all was working well. Now when we go into Smart Hub the Enter or Select button will not work (either on the remote or using the TV side panel) and i can't turn off the subtitles or press enter to make my movies full screen, i can't even change my Network Settings cause it's not letting me press enter, it's even letting me restore my TV to factory settings, idk what to do...is it anyway i can fix this problem? Funny thing is it lets me change from sources/inputs to the other, but i can't use them when i'm in the USB/Smart Hub options
