It was turned off when the whole house power went out during a thunderstorm. tried to use it afterwards, the input knob doesn't work. I can change inputs with the remote. the speakers don't work but the signal comes through on the headphones. I took it apart and checked all the internal fuses, they are fine. It was plugged into a surge protector along with multiple other components which are all working fine. when it was working, I would turn it on, it would click on and there would be a couple second delay before a second click and the sound would come on. During the delay the input knob wouldn't work but the volume would. now I just get the first click. what makes the second click? How do I get this thing clicking again?

the proposed solution led to the real solution. wiping the knob didn't make sense given the conditions under which it stopped working, and as far as replacing the pot meter, I was given no direction as to where this pot would be found. if I hadn't taken the knob off to clean the contacts I wouldn't have found the reset button so the end justifies the means. thanks for trying and hope that the reset button location will be helpful for others the proposed solution led to the real solution. wiping the knob didn't make sense given the conditions under which it stopped working, and as far as replacing the pot meter, I was given no direction as to where this pot would be found. if I hadn't taken the knob off to clean the contacts I wouldn't have found the reset button so the end justifies the means. thanks for trying and hope that the reset button location will be helpful for others
