    If the external monitor screen seems to be OK, then the LCD video cable or it's connectors on the mainboard and screen are probably the cause. From your photos, I suspect that re-seating the LCD video cable connnectors a few times to help clean the internal contacts will resolve the issue. Another possibility is the video cable wires passing thru the hinge area may be failing from wear and tear of opening and closing the lid too much. Replacement LCD video cables are fairly inexpensive, usually around $25usd.
