Repair of TS100

[TheAmmoniacal]

I accidentally used a 24 VAC output wall wart to power my TS100 and now the power regulation do not work. If I connect a power source to the iron the full power is now going to the tip continuously.

Any good guesses of where I should look? Maybe the CJQ4953?

I have attached what I believe is the TS100 schematic.
