Q2 431 voltage ref 431

I purchased this soldering station when it was on sale at amazon. It had a slew of one star reviews, but the price was low enough that even if the controller and PSU were toast, the handle tips and stand were worth more than the price. All of the reviews mentioned that the unit was either DOA, or died on the first use. I looked on Aliexpress and the first clue was that KSGER still sold the 220V version of this station, but all of the 110V versions had been discontinued. I figured That there was a problem with the 110V on the power suppply and the controller would be fine.

Hi Im Mark. I have lurked here for years, but havent contributed yet. My latest project is a KSGER soldering station with a dodgy power supply. I have found the most detailed answers to other searches on this forum so I am posting my half finished troubleshooting here

Looking forward to the experts
