proscan plded4016a 40-inch 1080p full hd led tv...I have that tv which seems to have the red/ white audio on the back and I'm trying to hook them up to LG Electronics CM4550 700W 2.1 Channel Shelf System (2015 Model)... that stereo which has the red/ white audio in jacks on the back of it. Why will hooking the red to the red and the white to the white not give me sound when hooked up from the tv to the stereo? I switched the stereo to Aux setting and I can't find an Aux setting on the tv. Thanks
