It used to be the case that TVs synced to the
mains frequency but I don't think that?s been the case since we went 625 line.
Despite some claims, I've never seen credible evidence of the existence of a TV that
"synced to the mains frequency", even for the 405-line system. I think it's
an urban legend. TVs sync to the recovered vertical sync pulse of the incoming video
signal.
