Hi, have just bought Samsung tv model ue55es8000u and am trying to get sound to play through my harman kardon receiver model 340. I have connected tv and receiver with both component and hdmi cables and cannot get the two things to connect. Any suggestions what I am doing wrong? Using component lead I connected av in from tv to vid1 to both in and out on the amp. Using hdmi cable I connected harman kardon DVD to play thru tv, picture and sound fine. There is no hdmi cable connector on back of my amp. Thank-you for your help.
