-Broken wires are most often causing problems on single-foil keyboards (as found in CPC 664, and 2nd generation CPC 464 keyboards). There is no chance to repair broken wires on the membrane by soldering (either the wire vaporizes, or the foil melts). However, one can '''repaint''' broken wires using conductive silver, which is sold as:

 === Rewired PC Keyboards ===
-Cut all wires on the circuit board, and rewire them as in the CPCs keyboard matrix. Sounds simple, but it's quite a lot of work. Of course it works only with keyboards that do have a real circuit board (eg. many inexpensive noname keyboards use boards), not with membrane based keyboards (eg. some of the infamous overpriced Cherry keyboards).
