Awesome thanks, I'll add those into my schematic and hopefully between us we'll have it done! I'm hoping to finish it tonight.
I have no electrical engineering background and quite a rudimentary understanding of these circuits so it helps seeing them labelled, as I'm tracing it OK but have no idea what I'm actually looking at (that TL431DBZ section makes no sense to me at all and I have no idea if I've traced it wrong or just don't understand it lol)
I have 100% killed my station anyway, accidentally ripped off the LCD connector and some pads and probably not worth the hassle of doing trace repairs - so once I have a new station I am going to desolder the old one and try to get some values for the caps.
And yeah I'm not sure what that pad PD1 leads to is about either. If anyone knows Chinese maybe they can translate the label. I think it's also worth noting the 'earth' wire on the 3-pin header is connected to earth at AC in but literally goes nowhere on the board at all, I have no idea why they even included it
