Massage or message? If message, all MIDI communication doesn't work?
Isn't it just problem of some setting? MIDI channel, filter or  
similar? Or hardware - bad cable, MIDI interface...?


Have you tried some reset or test mode? There must be something like  
this...


If nothing helps, it's time to open it, check cables and connectors,  
reseat them, also chips in socket (if any), and check the way of MIDI  
signal. Maybe optoisolator on the input is dead, or some other  
component.

Probably it's normal, when battery is low :-) Maybe it's time for  
changing it.
