Need help, 6800a keypad not working

Hello guys... I was trying to convert 6800a to 6800, suddenly my screw driver slips and hit the keypad filter (Z301). Now col 0 (marked red line ,see picture) is not working..

I try to apply this jumper but still not working.. Maybe diferent layout?

It is easy to make jumper but may problen is i dont know where is the input from UPP. I dont have also extra board to compare and trace the line..

Plss... need your help..
