MMM V2 collateral damage - repairable?

[GT35R]

Remember when the V2 faulty BEC's would take out your radio gear with it?

Well I was just wondering if anyone had identified a way to repair affected servos. I had 2 traxxas waterproof ones go silently - no smoke or anything and was hoping it might be just a tiny circuit fuse or something simple so I
can put them back in the Emaxx to sell it.
