Repair your Logitech Harmony 720 to continue one-touch control. Harmony remote controls provide one-touch controls by establishing "Activities" that send multiple commands with the touch of one button. The remote is programmed using a computer and allows for customisation of how to control your home theatre system. The Harmony 720 remote can have issues in regard to charging the batteries, controlling devices and others. Most of these problems can be repaired without needing a technician.
