It's been a while since I've posted here, but I have a problem and I couldn't think of a better place to get some sound A/V advice.
My Marantz SR7500 appears to have something wrong with it. Recently, the left front speaker has been dropping out on me and it's lasting longer and longer. In fact, right now, it's out and has been for days. In order to confirm that it wasn't speaker and/or wiring related, I re-terminated the banana plugs and reseated them. When this didn't work, I swapped the R and L speakers and the problem stayed w/ the zone and not the speaker. Finally, I moved the connections up to the front B plugs to make sure it wasn't related to the actual plugs on the receiver. The problem remained, even after going to B and switching over to the B speakers. Finally, I went into to the setup to run the speaker tone tests and all work, but the L front.
At this point, I think it's pretty much narrowed down to something under the hood. My knowledge of the inner workings of receivers is weak at best, so I can't narrow further.
So, I guess I'm wondering if anyone has ever had something like this happen w/ a receiver and whether the repair was a reasonable expense. I'm well out of warranty and really don't want to put down more than $100 to fix a relatively old receiver. I'm not necessarily in the same market for receiver ($700+) that I used to be financially, so I could replace it for say $250-400, which makes an expensive repair seem somewhat futile.
Hope that's enough to start a dialog. Thanks in advance for any and all feedback.
