Thanks for the input. I double checked the fuses (again), and this time I replaced the one that controls the TV and amplifier and sure enough it was burned out. All is good. The problem initially was that the fuses that Jayco provided do not allow you to see if the fuse is good.
Looking at the underside of the fuse it appeared to be good. And no, I didn't have a fuse checker on hand.
Point being, you need to step back if you can't resolve the problem the first time and think "simple" Don't overthink a problem.
