Who knows how to fully get the back off of a NI KK MK2 S49? I cleaned the board under the keys from a drink spill now I can't reattach the 3 ribbons because one screw or something is holding the back from coming off.
Sometimes there may be a screw hidden under a sticker plate or a rubber foot. If you feel it not giving when pulling it off, check around the area for anything that may be hiding a screw under it.
