This is most likely a loose LCD cable. Open the back (first pop off gray plastic, then unscrew three screws, then pop of the white plastic). Verify that the white markings on the LCD cable aligns with the white line on both connectors. If not, fix it. Check screen. Reassemble. I have done this twice recently as my kids drop the pad and this happens. Also it doesn´t hurt to secure the cable with tape.
