Long story short: I acquired a 575 logic board 'untested'. On testing it gave the boot chime followed very shortly by the death chimes. The board itself looked clean enough but I went ahead with a re-cap but this resulted in no improvement. After a wipe around with IPA, I can now see some clearly corroded and broken traces around the silkscreen for J10/C12:
Probing for continuity (mostly guessing here as I don't have a schematic) showed that only 3 of the traces are unbroken. I think they are beyond my ability to repair but I'm open to challenges and suggestions!
Thanks
PS: Apologies for the sloppy solder work around the new caps.
