Question about Compaq Presario 700 470024-192 Notebook
I saw a blue vertical line running through my screen. please help
A line from top to bottom or side to side is a dead or failed pixel sensor. There are hundreds of pixel sensors at the edges of the screen, when one fails it causes a line, the line can be red, blue, white, or black. Unfortunately, there is no way of repairing the line, other that replacing the screen.
