Bingo. There seems to be a crack somewhere “north” of the socket.
I have no idea how this could have happened.
Is there any chance to repair such a crack (i mean, once i was able to localize it – although i got no idea how to track it down atm)?
Other than to repair, i guess only option is to place some weight at the right position and to hope this will do the trick?
