Not sure that I understand the question. We have Verizon Fios. But the problem is the way that the TV is programmed to run through the Denon box that will not turn on.
It really would be best if you could post the make and model of each device in your system:
The Sony TV
The Denon Receiver
The Verizon Fios box
Any DVD or Blu Ray player
Game system
BTW, have you checked the fuse? Your owner manual will tell you where to find it, how to tell if it is blown, and the specs for a replacement.
