Something is wrong with the connection between the VGA controller and the LCD. Either that or damaged VGA controller itself.
It goes like that when the signal is not coming through properly. I've had that problem many times, and what I had to do was reseat the ribbon cable and apply some thick tape above it so that when I close the housing, it presses the controller and LCD tightly and makes sure that the ribbon cable seats firmly in the connector.
