Facing TV Problems? Ask a TV Technician.
Hello, First we are not Isymphony- this is Just Answer which is a group of tech familiar with working on all make and model of TV. That being said, the red and white jacks on the back of your LC19IH56- are not "Outputs"- which is what you need to connect a wireless headphone transmitter- they are "Input" only. The TV in fact has no audio output jacks, so the headphone transmitter would need to be connected directly to your Cable/SAT box red and white jacks.
