the sentence-initial discourse marker alone, never attached to a verb.

ところで shifts topic with no implied surprise, cleanly closing the previous line of talk before opening a new one; ところが shifts topic BECAUSE what follows contradicts or surprises against the expectation the previous sentence set up — using ところが for a neutral topic change overclaims a reversal that isn't there.
Lookalikes
ところだ is a predicate that always follows a verb, marking where an event sits relative to now (食[た]べているところだ "in the middle of eating"); this ところが never follows a verb — it opens a new sentence to announce an unexpected turn. The excluded たところが sense is the trap — a verb sitting right before ところが invites misreading it as ところだ's completion claim instead of this entry's surprise connective.
