I have a Yamaha RX-V1 and ran across a strange problem that I've seen mentioned here once before. This morning I was listening to some music and noticed the sound seemed really biased to the right channel. I started investigating and found that the left channel sounded heavily muted, but it was still playing some sound. So I moved the left speaker to the right, and that was ok, so I tried the B speaker connection, and then switched the right channel wire to the left connector and so on. Everything I did showed that the left channel just wasn't putting out much juice. Fortunately I remembered a recent discussion where someone mentioned that on some of the newer Yamaha receivers that don't use the connectors between the pre-in and pre-out, its possible for something to work loose and the amp gets turned off. I don't remember the specifics of this, but working on that assumption I grabbed a spare composite video cable, connected the pre-in to the pre-out and voila, it came back to life. So I removed the cable and it continued to work normally. This makes me a bit concerned though, I mean a $2k+ receiver shouldn't have problems like this. But I don't want to take it in to the shop because I couldn't live without it. I'm wondering if I should attach some connectors to the in/outs just to prevent this from happening again. Anybody have any thoughts on this?
