Check the schematics: http://eab.abime.net/showpost.php?p=...1&postcount=15
Is the crystal working? Is the kbd controller power up reset working? |

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! Last edited by danko; 21 July 2021 at 18:10. |
