I belive the reverse protection is a shorting diode (FET ?).

If you supplied power throught he DC connector on the front, you may
just have blow the fuse (one of the minute gadgets close by the DC
connector).

If you fed it through the white 6-pin connector on the board, you may
be behind the input protection circuit and you will be out of luck.
