The only audio output that your TV has seems to be the headphone out. If your home theater has an analog input (may have RCA jacks) you just need the appropriate cable. Your TV volume control will adjust this so make sure you start with the TV volume low and adjust so that it does not overload the HT. You will hear distortion if the TV volume is too high regardless of the volume setting on the HT.
