Need some help.....

So I have been using my Stage for a number of years at my church….no problem. Yesterday I sat at home and created a new performance for last nite. Everything worked perfectly here, I played for an hour using my headphones. Packed it up and later went to my church to prepare for our Christmas Eve service. Plugged everything in as usual…….and I had no output sound. Nothing. Everything was lit up but no tone stack, no effects, nothing. I was in a bit of a state of panic. Not enough time to sit and try to figure out what happened. I was finally able to get a simple dry sound out, but it was certainly not my normal tone. Can anyone shed some light on what may have gone wrong? Any help is certainly appreciated….
