McCormack DNA-1 problems

I have a McCormack DNA-1 amp that has worked perfectly for many years. Recently I turned the power switch on an no red light appeared. I checked the rear fuse and all 4 interior fuses and they are all OK. Does anybody have any ideas what might be the problem? Can anyone suggest a good qualified repair shop in the NY metro area or on the east coast?

Stereo Exchange can fix it. They have a really good service department and they're a dealer. (That's if nothing has changed. I haven't been there in a few years.)
