Hello Henrik!
your issue looks like a bad key contact : neither sound nor MIDI  ... 
the common point is this contact. You can clean it by yourself, or even 
replace it if necessary if you have some basic electronics DIYer 
experience. Be careful with the lot of screws in the plastic case and 
with the keyboard connectors. During the operation you can check the 
small diode (1N 4148 style) wired to the key contact,  i don't think it 
is the cause of your problem but who knows ? Most diode failures are 
short circuits, not open circuit...
Cheers.
J.F.
