“ON SCREEN CLOCK Does this set have an on screen clock which can be set to display on the TV screen or made to disappear and does it have a built in digital tuner where I could connect the set directly to my cable provider's coax cable coming out of my living room wall and be able to pick up some digital channels without having to rent a cable box from my cable TV provider to get their high end digital channels?
