We bought a wonderful Phillips TV for Christmas (40pfl4706) and a Samsung sound bar (hw-e450) that we were assured were completely compatible. We receive tv through an antenna and the TV works great, just beautiful! However we cannot get it hooked up to the sound bar. We tried AUX and HDMI, it appears to be trying to receive information from the sound bar instead of sending the sound to the sound bar. What are we doing wrong?
