Is it likely that bad solder joints would cause vertical foldover in a
mid-90s CRT television?

Yes, but it's more likely to be a bad cap.

Visual inspection is not enough. You need an ESR meter.

Maybe not; the ESR issues crop up mainly in high-performance
low voltage power supplies (like computers); the vertical
sweep circuit doesn't need a low-ESR capacitor. It will
take (and work well with) just about any capacitor with
adequate voltage rating and capacity.

The capacitor is inexpensive; just replace it with a new one,
don't bother with testing the old unit.
