We rec'd a Digital Adapter box and hooked it to your 19" Sylvania set. It worked right from the satrt. Recently we were given a 32" Magnavox MX 3297B. I swapped the cable connection but do not get any sound or picture. I plugged a DVD player into the AUX input and it works fine but still no cable. Do I need another piece of equipment or waht? New set was mfg in 1997
Have you checked with either the cable box maker or Magnavox? Although they'll both just blame each-other for the issue. If another device does not work on the same ports, those ports are probably dead.
