Hi Craig :
The Cap for 5V light checked O! the may be some short at Front panel interface board ? from the
switch boards shielding !
I may need to disassembly the front panel to clean the switch boards !

Not sure I understand that. It is very unlikely that there is a short on the board which mounts the
switches (vertical mode and horizontal mode). Check that the harmonica connectors are plugged in
correctly, and not one pin along in either direction
