FSESC 75100 repair

Hi everybody ! 

I just shorted a phase wire to a Hall sensor wire while throttle applied on a FSESC 75100. All the FETs are good but the FSESC won't turn on.

Do you guys think it may be fixable? And what could be the electrical components to test and change and resolder?

I have a spare 75100 for parts. 

Thanks all of you for the support!
