Hello. I was recently given (gift) a Klispch Promedia GMX d 5.1 system. Everything works fine except that there is no audio coming from the Left surround speaker. I tested the satellite and the cable on the front ports and both work fine when connected to the front outputs. And the Right surround works fine too. Has anyone had this type of problem before? Could this be possibly fixed? Any help will be greatly appreciated.

Someone may be along soon, familiar with your system and welcome.
