Once you have the keyboard open (see the link above), you'll need to remove the main board, and the smaller circuit boards, as well as the metal
bracing in the middle of the keyboard.
Make notes as to what goes where, and which cables go where. You don't want to mis-plug any cables, and you'll feel better
if you have a sketch to guide you.
With these boards are out of the way, you can remove the ten screws that secure the display board, which runs nearly the width of the keyboard. When all of the screws are removed from the top and bottom edges of this board, it should lift out.
To reinstall the display board, you'll need to put everything back together in reverse order. The tricky part will be to get the display
board back into place and aligned correctly. If you just lay it in place and screw it in, you will probably find that some of the
buttons won't press (or won't un-press) because they are wedged against the hole in the top panel. So instead, lay the board in place,
jiggle it slightly to work all of the buttons into the holes, and put just a couple of screws in to secure it. Flip the keyboard over
and make sure all of the buttons seem positioned correctly. If they seem good, put in several more screws, and then check to make sure
that every button works correctly (mechanically only, of course - there's no power to the keyboard). If all is well, put in the rest of
the screws, and reassemble the keyboard.
