Main board fried Mk3S?

I had a blob on the nozzle which pulled out the hot end thermistor wire with a small shower of sparks. 

Replaced the hot end but now get mintemp errors. Fuses are all fine, checked continuity with a multimeter. 

Seems like the main board is fried. Factory reset worked, but self test fails on testing the bed and hot end. 

Suggestions short of replacing the $100 EinsyRambo board?

I would start by asking support on chat.
