I don't know if you did this, but the first thing I do when we have this type of switch matrix problems, is to isolate if the problem is on one of the boards in the backbox or out in the cabinet.
Start the game.
Go in to Tests->Switch Edges.
Disconnect all the cables at the bottom of the CPU-board (J206/J207, J208/J209, J205 and J212.).
Short-circuit a switch with problem. Eg. pin 1 on connector J207 to pin 1 on J209 with a short cable, and switch 11 shall then get affected in the test.
If no switch register, more than one switch register or the incorrect switch registers, then the problem is not in the cabinet.
