cRio Power Light Not Turning on and no Activity

[Mike Copioli]

We had the same issue with one of our spare CRIO's. It in fact was the fuse. This crio was being used on our practice robot. We did not have time to wait for the RMA process, which BTW is very fast, so I decided to repair it myself. I do NOT recommend attempting this yourself as it will most likely void any warranty and is certainly in violation of the rules. Since this unit was only being used on the practice bot it did not matter. After opening the cRIO and observing the blizzard of debris that fell to the floor, I located a small surface mount fuse (1206 apx.) located near the power connector. I do not remember the ref. designator of the fuse but it is F?. Using a multimeter I tested the continuity of the fuse and verified that is was open. I replaced the fuse with a 2 amp slow-blow in that same package. I reassembled the unit this time WITH the optional rubber gasket kit. The cRIO is now working fine.

Once agian I do not recommend doing this but we needed it now.
