Hate to ask what seems obvious, but have you closed the green entirely? NO PLAY. I had trouble 2 years ago with two greens. Tried all the same things you are saying, while keeping the green in play. Zero success.
Full closure and play on a temp. green was the answer. It's relatively easy to grow grass when there aren't people stepping on it all day.
If you can't grow turf with no play, then there must be some deeper soil/drainage issue involved.
