The particular video defects you describe are usually a result of a bad connection between the video cable and the board.  The first thing to try is to re-seat the video cable as securely as you possibly can, and that often resolves the problem.  Make sure the cable is fully seated into the connector, and that the clasp is all the way down.  You can also clean the video connector and the socket, but be very careful.    If none of that does it, it's generally the video cable itself (not the board or the screen panel).
