The controls on top of the unit would be my first place to look. Then comes the input selector. Then the mode selector, etc etc.

Yes, that is where I was messing with when I got the channel to start working again.

I seeing the same issues on my C26, losing, then getting the right channel back. I'll try the switch cleaning procedures with contact cleaner and cloth swabs to see if I can clear it for some longer period of time....
