Try cleaning the cleaning the connectors on the board and the screen with a toothbrush and isopropyl alcohol. Make sure they are seated well, and make a satisfying click when put in place. Inspect the cables for pinches or tears, especially close to where they connect with the lcd. Just a little bending there can cause failure. Potentially look for a third screen to do a definitive test.
