Thanks! I'll do that and see what happens.

I installed that and then replaced IC30 and IC31. For a very short while I managed to recover the bank, patch, and write functionality but somewhere during this process it died again and is back to running one patch and multiple bank / patch LEDs. I'm quite certain I covered all the traces properly because I even had to add a few wires to connect points and the corrosion isn't major on this card. Do you have any suggestions on other ICs that may need inspection?
