Hi,
open the keyboard and check the board, whether you can see any corroded
parts.
Then check with a Ohm-Meter, whether there is contact if you push the
space bar.
If not, try to clean the button (often full of dust) with air pressure.
If yes, try to check the multiplex connection from the two pins of the
button to other buttons and to the arry with a lot of pins in one row
on top of the reverse side of the board. You can easily trace the
connections visually, this is a one layer board.
If there are interrupted connections, just resolder them (the button
itself, the perhaps interrupted connections) or just solder a new wire,
where corrosion took place and destroyed the connections
No need to throw away and replace the original part of your Lisa !
greetings TOM from Bavaria, the center of europe, the marvellous
castles of Koenig Ludwig e.g. Neuschwanstein and last but not least the
original Oktoberfest !

I have a keyboard with one key (space bar) not working. Any
suggestions?
Anyone have a working keyboard for sale?
