Hi Patrick,
This list has covered about everything regarding ringing dampers
except perhaps sypathetic vibration from a source other than the piano.
Are there any other instruments in the room with open strings? A
grandfather clock perhaps? I once had a complaint about ringing dampers
on a concert grand which was actually a pedal rod holding dampers off
the strings on an upright down below in the pit. Such sounds can be
deceiving.
Good Luck
