i have one mac classic with logic board damage from moisture and a bad flyback transformer, and one with a vertical deflection issue that i haven’t dug too deeply into troubleshooting yet. and yet that mac se was thrown into a creek for 6 months and still worked. absolutely nuts
i don’t have an oscilloscope and i’m so lazy that i haven’t reflowed the analog board yet but look this guy is SO close to working, except the fucking vertical deflection
I’d definitely start with re-flowing the flyback’s solder joints, it looks like there’s a bit of an issue with the horizontal deflection as well, otherwise that line would be the full size of the raster horizontally.
Analog board might need to also be recapped as well?
