Nevermind! I am happy to say that after replacing the VIA, the Mac boots!

Back with the same mac classic I had posted about before. Long story short, I was able to fix the analog board and am now getting a solid 5V as well as 12V. The mac bongs, but gets no further than some tightly packed diagonal lines. No blinking question mark. The interrupt switch leads to a sad...

Got a little stumped, and it took until now to get back into it. Indeed one of the traces on the logic board was severed, likely due to the cap leakage, and after a quick repair the 12V line is alive! All voltages are just as low as before, and I'm pretty sure it's something to do with the...

I haven't don't the most thorough job, just swabbing everything down with IPA before removing caps, after all caps were removed, and after new caps were installed. Looking at some schematics of the board, I'm pretty sure the 12V can be explained by my shoddy job at trace repair on the logic...

Sorry for disappearing, I had completely forgot to come back to this thread. Replaced DP3 and DP4, as well as TDA4605 and CNY17G (replaced with CNY17-3), and definitely some improvement, but the voltages are still weirdly low. 1V where 12V should be; no clue why. 3.5V on 5V, and -9.8V on -12V...

Meant to post about that. I'm getting 3.85V on the 5V rail (highly inadequate), and...1V on the 12V rail. Bad stuff. Ordered replacement parts that I've gathered from other posts on the Classic: TDA4605, 1N4148, and CNY17. Edit: Testing it again right now, and it's just fluctuating like crazy.

Recently picked up a broken mac classic for dirt cheap, turned it on and surprise surprise it was dead. Went through the usual process of recapping the logic board as well as the analog board (which had this weird rotten-smelling green goop that I had to clean up), but nothing appears to have...
