IFI isn't in the production or supply loop on this IR board yet.
For technical assistance I'd talk to Ben Wrightsman at Diversified Systems Inc. the manufacturers of the board.
For a replacement we'll probably have to go through FIRST.
I have a message in to FIRST and will let you know what I discover.
So far the reported failures are quite small in regards to the 1500+ boards produced, so I'm hopeful it's a less than 1% failure rate. Ben told me they sampled boards coming off the production line and the samples all passed, but not every board was tested due to the time constraints of the Christmas rush.
P.S. Based on keen101's experience it does sound as though teams should run these for some time to make sure they catch any marginal failures early.
