My screen has been acting weird latley. It would go black if it was not fully open or fully closed. It was annoying but not that big of a deal then today the screen just randomly got dark(as if I set the back light or w.e. all the way down). But after opening and closing it a couple times it brightened back up. After a couple seconds it just went pitch black. I opened and closed it again and I could see it trying to brighten up a couple times but was still really dark. I turned it off and on and it still is way too dark. I can see just barely sometimes after messing with it. So what should I do? Has this happened to anyone? Please help me..
