Scott, I have this Sony VAIO VPCS111FM Laptop PC - model PCG51211L with a display problem. I have attached photos of the symptom. I suspect that I may have a bad Video cable or bad LCD panel. I'm starting wonder if this symptom is caused by the mother board. The LCD panel displays white and blue vertical lines across the panel,unreadable display.The LCD panel's display becomes readable when an external monitor is plugged in,although the display is dimer than it should be with Brightness set at maximum. Do you think this could be a problem on the motherboard,such as the graphics chip? I can replace the LCD panel with a new LCD screen ,cost $64.99 plus labor.
