Can we fix a high voltage igniter?

During a live stream I was demonstrating this igniter unit and waved it back and forth vigorously to show how the spark changed. Then it suddenly stopped working with the green "charged" LED lit.
The circuitry is interesting, but quirky, and has some weird features like a MOSFET that bypasses the power switch to activate the microcontroller while it's charging, purely to light the charge status LEDs.

It appears that the generous arc length may have been part of the issue. When I was playing with it after the fix I managed to push the arc length a bit too far (again) and the transformer flashed over internally. When that happens the only fix is a new transformer.

The live streams mentioned in the video are on another channel called BigCliveLive - but be aware that it's more of an informal online pub-meet of technical people and the chat can go a bit weird at times.
