When the cable company offers you digital cable, you typically need a cable box to unscramble the digital channels. Therefore you need to connect either a coaxial cable from the cable box's RF output, if it has one, or connect 3 RCA cables from the yellow, white and red jacks on the rear panel of the cable box to the TV. Analog channels only (if available) will go straight thru over the coaxial RF hookup. They are not scrambled. Select the proper input source on the TV for the cable box.

Thank you for the response, the cable company did supply a box that was installed on a Wed. and on Thur. when they performed the switch over to digital the Ant A port stop working. I now have the cable box connected to the DVD output to input 2 of the TV.
without the DVD I would not be able to view anything.
at the time of the switch over all the tv's lost signal after the signals returned the one tv would not work through port A. with or without the box.(the first 22 channels are still analog)
