Sounds like the OP needs to do what I did and start learning how to read schematics. The guys on here trying to help solve the problem are all great and will probably get it solved but I remember awhile back their suggestions sounding like intense Mandarin Chinese to me when it came to schematics.
Reading and re-reading the section on Pinrepair regarding schematics is invaluable. I’ve got a long way to go but I’m learning. It’s also very liberating.
