I kept getting grey screen, now only grey screen. Portable screen works fine. I’ve tried all of the resets and even reinstalled IOS 12. Seems to be a common problem with New MacBook Pro? Test shows No issue ref. ADP000

Your appointment at an Apple-owned store for a hands-on evaluation is free, in warranty or out.
