There is a known defect with this receiver that I know some of you are aware of. I believe I may have been hit with it but I want to be sure. After close to a year of ownership now I noticed my LEFT FRONT effects speaker channel is dead. I tried replacing the wire, the terminals, the speaker, as well as swapping the left and right wire pairs on the receiver. The left channel appears to be dead alright. I understand the problem is tied to the PRE-OUT RCA jacks, but I thought this would only affect the MAIN speaker channels, not the effects channels. I have an above average amount of electronics skill. Is this something I can repair myself? I *could* send the unit back to the dealer, but the shipping cost would be tremendous. Any help appreciated.
