Yup, I went ahead and re-flowed all of the pins that
mount the flyback,
plus any large / heavy parts, power resistors, all of the connectors -
basically anything doing double-duty providing both mechanical and
electrical security.
But how could that bad joint blow the horizontal output? I don't know squat
about video circuitry, just never got into it.
The inductive "kick" from the monetary disconnection can be really
severe in a flyback, especially for the HOT (which is driving an
awful lot of current). Often times it only takes a few arcs to
destroy the thing. Flybacks and HOTs are usually replaced in pairs
because one usually kills the other.
