Help me out, please. We have a Philips Magnavox Smart Plus 32 inch TV about 7 years old. My wife recently purchased a set of RCA wireless headphones but I cannot find a headphone jack in the TV! Is there an adaptor so that I can plug the headphones into the audio output jacks in the rear of the TV? I also have a Hitachi FX VCR and a Sony DVD player, but no jacks on these boxes either.
