I have a set of T 912 wireless headphones. I am unable to set them up on the TV. I am using the white and red cables from the base station to the TV audio red and white. Do you have any instructions on...
The audio jacks on the TV are most likely inputs, not outputs. They're meant to take the audio signal from something like a DVD player, along with the video input on another jack, so you can play it through the TV. There isn't an audio signal coming out from those jacks, and if you connect your headphone transmitter to them all you'll get is silence. Almost all sets now have at least one set of AV inputs, but most don't give you outputs. The manufacturers figure the TV is just a display device, and not a signal source.
Unfortunately, there isn't any easy way to connect your wireless headphones if the TV doesn't have audio output jacks or a headphone connector. If you're comfortable with soldering and willing to do some modification to your TV, it's possible to add a headphone jack. Most people don't want to start tinkering with their sets, though.
If you're using your TV on a cable system without a converter box and the cable hooks right to the set, you're out of luck unless you're willing to add a headphone jack as I mentioned before. But if you have a cable converter box, or you're using a satellite receiver or other set-top box, you can use your headphones with those. These devices typically have direct audio and video outputs available on the rear panel, and you can use that audio output to feed the headphone transmitter.
What most people do these days is use a home theater receiver along with the TV. All sources (the cable box, DVD player, video game console, audio CD player, etc.) connect to the receiver, and the receiver's audio and video outputs go to the corresponding input jacks on the TV. This way, the TV is just the end of the line. The receiver also would provide an output for the wireless headphone transmitter. This system offers some advantages. You'll be able to connect the proper speakers to enjoy surround sound when not using headphones. And you'll be able to use your wireless headphones with the tuner and audio sources like music CDs when not watching TV.
