I'm back! And this is right up my alley. Let me try to help you here.
Check the back of your TV. If it's new, or pretty new, you should have 3 output jacks in these colors: Yellow, red, white. It should say output, or out over the three. You may have more, but find three that says out.
Yellow is VIDEO
Red is left channel sound
White is right channel sound.
You must have a stereo amplifier with different inputs on it, i.e. Phono, TV, DVD, Tape, etc. You must have a Headphone jack on the front of the amp...says "Headphones"
On the back of the amplifier, pick one of the channels, TV, DVD, any one of them.....right at that location you pick, you'll have a yellow, red, and white input jack (these are called RCA input jacks)
Now, get a set of wires that have a yellow, red, and white male RCA jacks on BOTH ends of the wires. (and long enough to run from your TV to the stereo amp. 6 feet usually works)
Plug the RED RCA jack into the BACK of your TV that has the RED output female jack on it....run the other end of it to your amp back to the RED input RCA jack. Do the same for the white male jack, plug the white end into the back of your TV right next to the RED output and run that to the back of your amp to the white INPUT next to the RED you just plugged in. That's it.
THEN, plug in a stereo headphone set into the jack in the front of your amplifier........you can now listen to the TV while turning the sound off or down on the TV........the TV volume is separate from your headphone volume, which is controlled by the amplifier volume control on the channel you chose that you plugged the wires into at the back of your amp......volume is either by remote control that comes with amps or by doing it manually.
The TV volume is controlled by the TV volume......it can be as loud of soft as anyone wants it in the room.....thus, people with good hearing can listen to the TV at the volume that's comfortable for them, and you can listen through headphones the TV sound through the amplifier. You'll have two separate sound controls now. One for the people in the room, and one for you....neither one will conflict with each other. You can listen to your headphones as loud as you want, it will not affect the TV volume at all. Got it? That's how I've been doing it for years.....so if I watch a program late at night, I use headphones, and the TV sound is off. Won't disturb anyone.
Of course, using closed captioned with this method helps even more.
If you need any more help here, let me know. I just hope I've been some help for you.
