 All the voltages on the small board are within spec, all LED's work on both boards, all other voltages but oa are within spec on large board, oa measures 201v  range is 75v -100v. Any ideas on issues ?

You have 201V on OA on the large PC board?

I would reflow the joints on the large PC board and don't hesitate to post some build pics here.
