What can I repair so my screen will function correctly?

My name is Anthony and Im having problems with my Touchpad. Five days ago it fell about 3 feet down and the power button went 1/6 out of place and I gently shook the screen once so it went back to place. After that the middle part of the tablet did not recognize touch and the only way to use it was by applying pressure to the bottom part of the screen (as long as the home button was at the bottom because thats the only orientation that worked! I already dissassembled it so I want to know how to proceed from here please. Thank you very much
