Welcome to the forum!
I don't have a Wildcat, but I'm sure the set-up is similar. Shut off the TV's internal speakers through the audio section of the TV menu. Select the proper input/band on the Jensen. On my Rockwood, the TV plays through the AV1 input on the Concertone. The Wildcat may use a different input, but there's only a few to try.
