If your display is winks out as you tilt the display (lit and then not lit) that implies you have a bad cable or a bad/loose connection on the logic board. Follow this IFIXIT guide: [guide|5140|MacBook Pro 13" Unibody Early 2011 Display Replacement]. Follow the steps to Step 4, as we are checking the display cable we'll jump down to Step 14. See if reseating the cable fixes the problem. If not did you see any staining or corrosion around the cable connection on the logic board as well as the cable connector? If you don't see any damage you'll need to replace the complete display assembly. If you do see some damage take a good set of pictures so we can see it.
