Well the other day, my sister connected a brand new set of headphones to our TV. After she took out the headphones, we couldn't hear anything on our TV. Why is it? It isn't mute at all. But something strange happened. Every-time when I connect the headphones to the TV, we can hear what the TV is saying. Weird. So what's wrong with my TV, when you have the headphones, you can hear. No headphones, you can't hear at all. So please help help us ASAP.
