What would you suggest to me at this point?

Two dissimilar metals/alloys in contact, with an electrical potential across them, will cause further corrosion. Thus, you should consider replacing the I/O flex board as suggested.

If it is either one of the two center contacts, these just provide a contact connection for the batteries in the tray. I've used some sticky back copper tape to fashion a contact that can be applied over the top of the two center contacts.

No dissimilar metal problems!
