Casio DG-20, fretboard

When I got it, the DG-20 had serious problems deciding whether a note was held on the fretboard or not. In closer inspection it turned out that a previous owner had attempted some kind of repairs on the fretboard. Like said, it’s too bad that this person had decided to remove the rubber mat by pulling it off from the fretboard instead of doing it properly, in turn tearing the mat into three slices. To illustrate the structure just for you (<3), I made the this fancy mspaint diagram:

So in its original configuration, the rubber mat attaches to the fretboard with the bits wrapping around the PCB edges. Once this combination is installed to the neck (double-sided tape and two screws used on the PCB), the mat will stay nicely put although it’s not actually fastened with anything else than surface contact.
