I accidentally shorted the DC power supply pins on the sbRIO 9612 FPGA board and my DC power supply had a very large current limit. Now, the FPGA board does not power up. To see if the fuse blew up, I replaced the fuse with a wire to see if the board works now. It did not. Which means, something other than the fuse is not working as well. What could I have possibly fried in NI sbRIO FPGA board when I shorted power terminals? It is a 1000$ board and the service repair quotes 500$. I want to try to fix it by myself, if I can. Does any one have a schematic of NI sbRIO9612 FPGA board or any suggestions on how to proceed with debugging this board.
