The Live TV guide is not updating? Is there a way to get that to work? I don't have a cable box on this TV because I use it on another TV. Just a cable coax connected on this one. Not sure why the TV guide won't update and I don't get all the channels i.e. the golf channel which I get on my other TV? I choose Auto program when setting up channels... should I have chosen something else? My cable provider is Cox. Any help would be appreciated.
