Hey, everyone. I'm posting again about my SE/30. I had originally recovered it from Simasimac status back in 2023. Then, due to the sound issue it was having, it's basically just been sitting in my closet. Figured it was time to try my hand at it again.
Here's a video of the problem:
It will intermittently chime correctly, but most of the time you'll just get a staticky chime and crackles that persist until you trigger the sound enough times. It appears to "fix itself" after that. Now I'm not super skilled with soldering or hardware in general (just hobbyist level), but I can look through the schematics and see what's connected and what isn't. I fixed the Simasimac issue with a lot of bodge wires and (admittedly) less than stellar soldering. I think I've narrowed the problem down to the circuitry between the ASC and Y3. Here's a video showing why I think this way:
I tried soldering bodge wires between those pins on the ASC and Y3, but no dice. I also tried reflowing that whole row of pins on the ASC, but that didn't work either. I removed the bodge wires so now I'm back to square one. Here are the most recent pictures of the board I have. The only thing I did after this was soak it in IPA overnight to remove a lot of the flux residue.
As you can see, it's kind of a mess haha. Any help would be appreciated! Other than the sound, it's a fully working board so really hoping to fully repair it. Thanks everyone!
