I am now the sad owner of an Onkyo TX-SR805 that is missing it's front left channel. It was my first Onkyo purchase, and perhaps my last. I connected the left front speaker to the center channel with the same wire to confirm the wire was okay, and the speaker was okay. It's producing absolutely no sound. Just over 4 years old, makes me sad as I love this receiver. How much does something like this cost to fix? Should I just replace? Is it possible it's something simple? I can't really directly put down the time that it failed, though I do remember a day or two ago when we were watching a movie, a point when all of the speakers stopped making sound for just a second. I heard no pop, and there was no hot smell though or anything. I have taken very good care of this receiver, keeping the cabinet open, and I affixed a home theater cooling fan to the top that pulls the hot air out of it at all times when it's operating shortly after I purchased it in Dec 2007. Tried a factory reset and that didn't do it either. Just aggravating because it has never gotten worked too hard, never used the video processing (just pass thoruhg), and it's connected to Paradigm bookshelf speakers so it's never been worked much either.
