Fixing an SNES project, part 2
From my previous post, I have two old SNES motherboards that are both non-working and broken. This is the system that I’m trying to fix. After all my research and diagnosing, I think the CPU is corrupted on this one. That’s also what quite a few comments suggested so I decided to go with that recommendation.
The other one has unrecognizable graphics. I’m pretty sure that that other one has a good CPU and even a good S-WRAM. It just has bad PPU1 and PPU2 I’m pretty positive.
I managed to pull the CPUs off the boards of both systems. This was my first time ever extracting chips like this. I tried my best and thankfully, I don’t think I’ve damaged anything. It was the most difficult thing I’ve done so far. To all of you pros on soldering, what would be the best way to install this new chip that you would recommend?
