Recently, the screen went partially blank. If you divide the screen's width into 6 sections, the far left works, the next 2 do not (black area) and the right 3 work. I can make the windows smaller and work on the right side.
I've hooked to an external monitor with no issues at all. Took the laptop apart and disconnected then reconnected the ribbon cable at both ends. Same thing. This morning the black bars turned to blue and then back to black.
I am not new to tearing a computer down, but am new to working with laptops. Any advice?
