Exclamation cRIO NOT WORKING

Our cRIO is not turning on.

Problem: Power from Battery -> PD board -> 24V into the power connector to the cRIO all works. We've tested Volts and Ohms on input and output to the cRIO. The power supply is fine up UNTIL it goes Through the cRIO power connector onto the PCB (Printed circuit board). After that, we get none of the LEDs lighting up, no lights; signal or connector; for the Ethernet port, and the CMOS 3V battery is still running at 3V. There is no Voltage output on the 5V marking on the PCB. The fuse isn't blown either.

cRIO Module: NI cRIO-FRC
Issued: 2010-2011 build season.
On the PCB, the reverse-side has discoloration and it looks like something MAY have shorted something or another. It looks to be water damage or metal burning, but I can't be sure.
