I replaced one of the IC's near the battery, which had black legs.
Apart from that the whole board really looks ok, even the the traces.
And I checked every trace with the multimeter.
Personally I think it can't be the KLM-367, because saving works again,
like it did before. The fact that only every sixth note is wrong is in
my opinion a clear indicator for a problem on the KLM-366. And that
looks even better than the KLM-367. But I will see.

One thing to note is: That small cable that goes from the battery to
the other board above was black from the inside. On the other side it
was still copper-colored. So I guess some of that icky battery stuff
must have been crawling up inside of the cable. So I consider it to be
a good idea to check that cable as well in order to replace it if
needed.

What's the problem with your Polysix?
