Hi Joe,
here is a quick troubleshooting list that you should do:
- Run through the Cleaning instructions for your cRIO and install the gaskets if you have not already. Here is a link to the directions on how to do so

- Double Check Power connections, Make sure to pay attention to the PD Board to see if any of its LED flicker.
- If that fails you might consider calling the NI Customer Service to start the RMA process at 866.275.6964
You might consider posting over at ni.com/first as we monitor that much more closely than CD.
Please keep us posted on how things turn out
