Yeah, I'm not sure either, sLide...  It has been over a week since I posted and no one responded back to me either...  I have been having a hell of a time with my CoinTerra miners as well and thought I did all the right things and I'm still not getting them to mine at optimal output and they are still overheating.

Just from my very basic understanding of these machines and from what I have learned from this forum, I would think that perhaps either you have some blown or about to blow or burn out Mosfets or other electrolytics on the board (the medium sized to small electrical components soldered into the outsides of the boards around the GoldStrike chips and liquid cooling blocks).  The chips could also be having serious instant-overheating issues, so the board is shutting them down before the BeagleBone boots up all the way so your CTA's are not even coming up at all when you boot it up.  The best thing to check is to take the cover off and power it up and see what the LED chaser lights at the front of the boards are doing.  If they light up and promptly go out, it could be from overheating the chips.  If they don't light up at all and/or the fans aren't running at all, there could be another issue with the board that has basically killed it. Either something is causing the board to short out or otherwise stop the flow of electricity from flowing though all of the circuits.  It does seem kind of surprising that both boards would be dead in the machine though - usually I have seen that only one board will go completely down but the other will tend to keep working for whatever reason.

Good luck with it...  You'll probably need it as I haven't had too much luck with these things myself! lol...
