forget to isolate sd/su 4 hv screws=blown sc

[bman4]

got 7 blink did what i though was isolating the sd/su buy unplugging them but leaving the 4 screws.

there was a loud pop then i notice ic 748/mip 391 burnt along with front row igbt's shorted.

i need to know if anything else got damaged since the surge hit all the way to mip391.

the question is how much damage can this cause to sc
