Everyday somthing new

[Newton Hunt]

THis sounds suspiciously as if the strings themselves are not to be
believed. :)

Is it at all possible that some part of the plate and bridge are
contacting each other, enough to cause the bridge to stop vibrating.  I
am thinking changes in humidity could cause the problem.

Check the board crown in that area.

Tap on the board in and around that area to see if there are dead areas.

Try to get something under the bridge apron and lift to see if that
changes anything.

Check the bridge cap.
