What's important is ic2 receives power from the 5v regulator . The oscillator is connected and drive + hv sense is connected to the rest of the circuitry. If those check out (continuity) and the FET is not shorted, but something is still causing the 5v regulator to overheat and go into shutdown, likely Ic2 was damaged.
The only real way forward if that was the case, is to contact Pete and see if you can get a replacement. That Ic has to be programmed with code (it comes blank when bought).
