That's strange. If you still own the faulty case please take a picture of
the pc board and send it directly to my email address ( hardware@... ).
I'll have to check with the factory what happened. Pay attention that the
external supply (wall wart) has to be positioned outside the case in the
carton. Now and then we have problems if the supply is positioned inside the
case during transportation because then it may damage the parts of the pc
board (e.g. electrolytic capacitors, voltage regulators/heat sinks, pin
headers).

Sorry for the troubles
