Fried DMDs wrong voltage

Hi I have a number of dmds arranged in a 3x3 configuration, recently I suspect the dmd was connected to 12v instead of the 5v it specifys.
Currently the dmd array is not working and I was wondering how I would go about testing and fixing the boards.

ie Where is the voltage reg? Is there an overvoltege fuse or protector that I can replace? What is likely to have blown?

thanks in advance
