Unplug the power, open the case and try to locate some electrolytic capasitors is series with the audio at the channel with the problem. One of them must be blown.

Sorry for my previous post, as you can imagine it's not your case. I'll be back soon.
As your amplifier is indeed a very good one, I suggest you to keep trying to fix it. All the symptoms that you refer are at the power supply device, maybe the transformer is partly blown out. Before attempting to get it at a technician, unplug the power and unscrew the cover. At the front right side (just behind the power switch) you will see a pcb with one capacitor, one resistor and one fuse (glass type). Check and replace the fuse if it is faulty. I can suggest you checking the connections at the pcb itself, but it is not so easy if you are not familiar. Here is a photo of what I'm talking to.
Sorry again for my first post.
