hi my xl7 is behaving weirdly. the display scrambles/flickers, it freezes sometimes... so i decided to boot it in diagnostics mode. now it tells me midi test failed - port a in/out jumpered? so i tried different (working) cables, disconnected all cables, but it keeps returning that error... somebody out there has an idea what could be the problem?
