This happened to me. I searched the Net in vain for answers.
I learned that those in the know know that the lack of green light means your H9 needs repair. Few will respond to a question like this b/c they don’t want to be the bearer of bad news.
They don’t want to break this to you: stop wasting your time looking for answers. Just send it to Eventide with $100 (a very good deal). Good luck.
