I have a Harmon Kardon AVR320, with 5 channel speakers (Onkyo), and the left front (LF) speaker has no sound. Hope to get some advice.
I connected the LF speaker to the wire for the RF speaker and it has sound, so speaker is not the issue. Then I connected the RF speaker wire to the connections for the LF speaker and then there's no sound from that speaker, so the problem seems to be with the receiver - it no longer powers the LF speaker connections. Any suggestions on how to fix this?
