Discussion about the Korg PolySix synthesizer

It's me again. I found a tiny little dot of acid on one of those points 
in CN06 connector. This is the area where the upper boards of 
controls&knobs are connected to the main cpu board as you know. Could 
that be the culprit of my memory problem ? Maybe 'Write Enable' track 
goes through one of these points ? See picture:
