sounds like the ribbon connector is worn/failing .

Yep, I think you're right.

I found a service manual that, while it isn't very detailed, shows what I assume is the problematic piece. The zoom encoder part of the encoder FPC. I'm guessing that it's, as you say, either worn and about to fail, or simply dirty/corroded in some places.

I can't yet tell if it's worth trying to open up and remedy on my own.
