Is our cRIO toast?

[Jagbots(Mark)]

Team Jagbots, 2929, could use some help in troubleshooting our cRIO.

In our regional this last weekend (Cascade in Seattle) we made it to the second round of quarterfinals without a hitch but lost communications during it. We took a voltometer to the robot and found that it was getting power all the way up to the cRIO, but something internal must have been causing a problem. The cRIO's power button did not light.

We confirmed this in several ways:
-Flipped the safety mode dipswitch on the cRIO
-Checked if the cRIO received 24v power (checked for current above and below connector)
-Vacummed metal filings and checked for shorts

So before we have an expert crack open our cRIO, what exactly should we test to make sure our cRIO can be repaired, has anyone had a problem like this?
