Hello, I am new and yes I ran a search but was unable to locate anything that could help me. I have been having a problem with my Center Channel, there is almost no sound coming out of it it is almost like it is on mute while all other channels are working fine. When I do a test tone it has a odd noise compared to the other speakers. I took it in to ABL Service in Madison Heights, MI because the receiver is still under warranty. They said they "UNLOCKED" it and I need to read my owners manual. Needless to say when I brought it back home nothing was fixed. I have tested 5 Center speakers all with the same results. I don;t know what I am more mad about, the center still not working or the incompetent service provided. Can any one give any insite on the Center Channel not working?
