How common is it for a receiver to need to be unplugged for 15 minutes to get it to work? Any time I move a receiver from one room to another I have to leave it unplugged for 15 minutes or it doesn't start. It gets caught in a boot cycle loop or a power cycle occurs every 15 seconds, I'm not sure how to describe it. Both of those seems to be pretty accurate. Is there a name for this so I can look it up? How common is it and should I be concerned it will have more problems? It is an owned unit so I hope not.
