I also gave an LG i hooked up to the regular headphone plug behind tv, doesn't say headphones but has same plug as if you were going to plug in regular head phones, than when everything is hooked up, go to settings or apps depending on your tv, than go to audio than change from tv speakers to headphones, than u have to set the volume on your headphones on high, than you control volume by adjusting volume on tv with control and don't touch volume on headphone anymore, i also have a samsung, which works different with them, i also plug in to same jack on tv, but on this set, i can lower volume on tv, and adjust only on headphones, i guess all tv's work a little different, hope this helps, also on the LG, the headphone will turn on only when u select headphones at settings...
