Sounds like the LCD connections are loose. Luckily, there is a service manual that shows how to open it. [document|989] Open it up, unlock the ZIF locks, clean the connections with a microfiber cloth, put the ZIF back in, flip down the lock, and you should be good to go! If that doesn't fix it, it must be the logic board or LCD. Hope this helps!
