It seems there is little information on how you can fix this yourself. Most of the thread referring to black screen end wit the OP never saying if they resolved the problem or not. If you do a search for black screen you will find some. If you are willing to try her is something you can try https://nikonites.com/forum/threads/is-she-dead-jim.45073/post-751048. See post #14. Good luck and let us know if you are able to resolve this.
