So I my laptop (Lenovo y50) screen has been acting up lately. Basically when I open the screen it will turn black when I push the screen back and turn back on when I pull it back toward me. A few days after that was happening it continued to get worse and would act the same way except the screen would only be on if I pulled it back to about a 45 degree angle so I obviously can't see the screen very well. I'm not sure what this could be.
