Totally black screen after lcd replacement, not backlight
I replaced a cracked lcd and digitizer on and ipad min hd. I was careful to remove battery and not reconnect until the new screen was in place but after fitting it's totally dead.
I read posts on backlight issues but there seems to be nothing on screen at all. It still boots as I can see it in iTunes and it beeps when charging but the screen is completely dead, I've tried 2 now with the same results..
When I plug the old cracked screen in there is light and colour but it's too damaged to show an image.
What components should I be testing? And if possible replace
