Hello forum!
I picked up a non-functional Macintosh Classic (1991) and I would love to know if there is a chance to get this working again. I've never done a repair of this sort before, but I have OK'ish soldering skills. I'm hoping to get some advice from you all as I work through.
The state of the system when I got it: Powers on but nothing shows up on the screen. The screen itself doesn't seem to be on.
I have opened up the case and pulled out the logic and analog boards (after safely discharging).
Visually inspecting the boards, I don't see any major corrosion or leakage. Some pins have rust, but for the most part seems OK. On the logic board, the capacitor cans also seemed OK visually.. no obvious signs of leakage. But as soon as I touched one of them, it immediately came off. So did a few other caps. I then removed the rest of them as well. So obviously these need to be replaced. I have ordered the cap kits from Console 5. However, looking at the pads, I cannot tell if they are intact. I tried apply some solder on them and on some of the pads the solder sticks, but for a few pads it doesn't seem to be holding. I'm attaching some images. Would love to hear from an experienced pair of eyes on how things stand.
