I have two identical keyboards. One is a bit worn out but still perfectly functional, the other is faulty but is physically in good condition. I want to take the good parts from each and combine them into one decent keyboard. Really I want to just swap the whole internal keypad thing inside.
But the "faulty" keyboard has some specific keys that are not working. They are 1,2,3,4,5,6,7,8,9,0,-,=, PgUp,PgDn and End. So most of the buttons in some specific rows/columns. It also seems to randomly disconnect from the PC (Let me be clear, this keyboard has never had anything spilled on it, it has barely ever been used).
What I would like to know, is if the problems are because of a faulty chip or because of a faulty keypad circuit. I dont want to go dismantling things without knowing in advance.
If its the chip I can happily just swap the keypads out, but if the keypad itself is faulty that pretty much screws the whole idea.
