I don't know have a two kdb controller same problem....I will try to change with one kdb working.

Update 1: put a working kdb controller the problem remain the same,I am convinced that the caps lock rubber closes the circuit....it is impossible the all key pads to be damaged.

Update 2: i try the old membrane with kbd controller and a one plug rubber for testing, all the key pads results damaged this is absurd!
