A certain TI-85 (which I will try to fix, but is not mine) has a
strange problem. The display does not display a strip of graphics.
Everything else is fine, but about 20 rows just don't work. They DO
work sometimes, but are then distorted. The LCD is connected to the
board with a ridiculously long ribbon connector, folded several times,
made out of thin plastic. Any ideas?

Chances are rather strong that there is a broken conductor in that
cable that makes intermittent contact, since you mention that a
consistent block of the display is flaky. _Might_ be a solder joint
on a chip, but those flat folded cables break often. The cable
might even be loose in the connector if you're lucky.
