When my controller becomes idle and goes in sleep mode, my console doesn't re-sync with it. As normal, there are no rings on the console letting me know the controller is idle and when I press the guide button the controller just flashes continuously. It only happens with this console because I also use the same controller with another console and it works fine. What is preventing the console from not recognizing the controller? It has worked fine for a year and then all of a sudden...nothing.
