Plugged Power plug into the PA Jack. Now dead.

I have two (tr)usdx units that were both working fine. In a moment of carelessness, I plugged the 12 v power plug into the PA socket. The display went crazy and now is dead.
I tried unplugging the RF board and applying power via the USB port, the unit doesn't display anything, but I noticed that U5 gets very hot! When I put 12 volts in the power port (without any USB), U5 doesn't heat up.
Is this unit salvageable? Any suggestions on where to start would be appreciated!
