MMM V3 - Castle, I need some help

[Helly]

I receive my MMM v3 this week end, i put it up on my E-revo and start to test it…
Here is my config:

E-revo
Neu 1515/2D/F
MMM…, no mod, no external BEC (punch control 100%, start: low, timing motor: 0…)
7S2P A123
Gearing: 24/62

First test was with my first radio, the TQ one (27Mhz) who was working perfectly with my MM on 5S2P:
At the start the MMM worked perfectly
and more I ran it, more I pushed it, and more the Revo hesitated to accelerate when I was away from it… (still worked good when I was near it even with hard acceleration...)

Second test was with the 41Mhz one,
Ran like a champ… the Revo didn’t glitch anymore, no problem…Perfect…
10min later, after a bad wheeling, my Revo was on the body…I was far away, so the radio system started to glitch... After that, The MMM was strange, the servo worked normaly, but when I tried to accelerate, the Revo just moved a little bit, nothing more….
MMM OFF… wait a bit… ON and something was wrong with the led… OFF 1second after.
Let time for temp down, ON and welcome to the white smoke !!!

Now my MMM look like that: nothing's wrong...(maybe the "223D" composant is dead..., don't know)


Just the two fan wire, who are cut by half... maybe short cut here:


Is it possible that it's juste the fan who failed?
What can be wrong on this MMM???
Is it possible that he can work again?

Thank you Castle to answer here.
