Don't assume the connection is good because you can't see anything
wrong with it.  I made this mistake when I attempted to fix an
ADB keyboard with similar problems.  I even think it's the same
connection.  I reheated all the other connections except this
particular one.  The second time I looked at it the microfine
crack showed up when I applied pressure to the connection.
Reheating this fixed the problem.
