My onkyo 605 receiver is shutting off on its own when it reaches 60 on the volume nob. I read up on the internet this might be the "PROTECT" thing that shuts itself off from pushing itself to hard... I've had it over 60 before though and I thought it might have to do hooking my center up, but I turned the center off and it still happens. Does anyone know what a problem might be? Its a brand new receiver, and its not over heating or anything...Thanks
