Korg MonoPoly Synthesizer Repair. One of my customers brought me this really nice MonoPoly. It should be given a general overhaul, as some things no longer worked properly. In addition, all of the electrolytic capacitors should be replaced because, as can be seen in this picture, they were once again spreading your aggressive substance over your legs. This can always be seen from the dark spots (discoloration) on the circuit board.
The keyboard contacts were also worn out. Some of them no longer had a function, or the key only emitted a tone when it was pressed very hard.
