tuner buzzzzzing like hell

[haesslich]

the (klira branded, probably schaller) tuners from my oold framus rattle like hell since today. yesterday was ok, today is dramatic :-(
it rattles when playing the 3 heaviest strings, and it seems to come from any single tuner, as it stops rattling as soon as i hold any tuner-head (is it called head? the thing to turn around :-) ).
why can this happen absolutely spontaneously from yesterday to today? and what can i do against it?

update: it's possibly some screw inside the tuner? can this be possible?

hmmmm the only thing i can think of is that the nut holding the tuner to the headstock is lose but it dosent really sound like thats the case... good luck with it dude, sorry i couldent help more.

Tighten the small screw on the tip of the tuner button.  Not real tight just snug up.

tried that
did not help.
i gave it to the luthier this morning.
