I have a yamaha rx-v765 and the left speaker channel constantly hisses. I double checked my speaker cables and switched speakers so I know those aren't the issue.
I unplugged everything so right now I just have the receiver and 2 front speakers. When I turn it on, like I said, the left channel constantly hisses. The other thing I noticed is that when I turn the receiver off, it makes a popping noise in that channel. I took the cover off to see if I could see any loose wires, but everything looks legit to me, but I'm not a big audio guy so there could be something I'm missing.
Does anyone have any idea what could be wrong?
