Horizontal screen lines (1 pixel) - can it be fixed?
Follow Discussion
Hey, my notebook recently started showing horizontal lines at the full weight of the display. The lines are about (I'm guessing) 1 px and in an attempt to close the lid and then reopen it (without shutting off or sleeping) would eventually disappear. Those lines are presented sometimes at pre-os environment (bios) so I guess it's either GPU chip failure or cable connection problem? How can I fix that?

go to the service :)
You`re right it is either artefacts from deffective video chip or screwed up cable connecting the matrix to the motherboard....I doubt that you`ll be able to fix it by yourself...
If it fixes itself when opening and closing like you said, I believe that the issue is in the cable, probably around the hinge area as it takes the most beating.

Gives an idea how the wires are connected, where to find them and what will be needed in order to fix 'em. My choice would be to take it to professionals and leave them to do their job properly.
