i am with richard on this one with an addition.
first it seems really strange that 2 keyboards would be dead. possible, but doesnt seem likely. like richard mentioned, confirm that you really have the right schematics.
second, is like has been said, all the internet searches talk about dead keypad as power. does the power come from the relays in the control box? one person had a bad relay. you said you swapped them around. how many are inside it?
is there any fuses between the batteries in the back and the control box?
