Additionally, the plastic-backed 71's have a "golden zebra" connecting the two PCB's which is highly susceptible to corrosion from leaking batteries. It is likely destroyed.

I had no idea about the change in battery contacts! Thanks for letting me know.

Alas, that may well be the case for the severely damaged unit. That would explain why I had intermittent luck getting it to work, but nothing reliable, and it's probably wholly failed.
