Casio DG-10 Digital Guitar Repair - But will that fretboard work again?

This is a repair video of the classic 1980s Casio DG-10 digital guitar. I go through the disassembly, diagnosis and repair of a broken fretboard that is no longer playing the correct notes when the frets are being pressed.
As the DG-20 is basically the same guitar but with midi this video may come in handy for that to.
