Mike,
I had a similar problem – check out my video at the link below. I burned a DVD and took it to my LHS who put in a call to HH who replaced the 5n1. While I was waiting for the new 5n1, I scored a second BNF MCX to feed the monkey on my back [

].
Now I can have one on the bench to beat on while keeping the other airworthy.
