Hi, Josh:-

Dunno, but I'd imagine it will either be pretty straightforward to
repair, or about impossible (as in the proprietary micro is fried).
(not to say one couldn't retrofit all kinds of stuff, but that's not
really a repair).

Assuming you're talking about a thyristor trigger transformer, the
likely culprit is a failure of thyristor (probably a triac/alternistor,
could also be an SCR) or the connections to it, causing the pulse
transformer to die. If you're lucky, the chain of events terminated
there.
