I have a Fanuc R-J3iB controller and only 2 of the EE inputs are working (1 and 4)… we had the EE pin out messed up and wired it wrong initially, I am assuming we burned out the other inputs.
Can we replace a chip on the board for the inputs? There is 3 small DIP16 chips that are socketed and removable, but only seem to be for the outputs…
