Blown up electrical board

[DhavalVashi]

We are having a problem with our control system. When we try to get feed from the camera, the robot goes into watchdog mode. this started happening 3-4 days ago. prior to that, everything was working perfectly. the camera would track and follow and shoot and all that. but now as soon as we enable the robot, it goes into watchdog mode because the camera does not get any information to send to the cRio. the camera light on the cRio is solid orange (even tho it should be flashing to show data transfer). then we called NI and they said we might have reset the password. so we did that and then we went to test it on our practice robot but the cRio does not turn on. when we remove the WAGO connector from the cRio side to measure voltage, we get 24.5V, but when we plug it back into the cRio, we get 3.27V. we tried it with many batteries. we tried using 3 different power distribution board. but no luck. So then we called NI again, and they said lots of teams have the same problem and that they will send us another cRio overnight. we are still waiting for the new one to arrive but would like your feed back on what might be wrong. we also tried using the old backup code from 2 weeks ago which we knew worked for sure!
we look forward to your opinion.
