You say all your black and white sets work fine. Those sets are analog. So, whatever you are plugging into the antenna terminals of those sets should work with your analog color set.

When you are describing the hookup, please be specific and step by step, like:
1. coax from wall to cable box.
2. cable box output (say what it is called on the box) to coax cable to matching transformer
3. matching transformer to TV antenna screw terminals
