Hello ladies and getlemen,
My HP laptop has a stable white vertical line of pixels that appears only sometimes. It does show in the Bios. Moving the screen up and down will make another line temporarly appear. Is it the screen itself or the ribbon cable? And if it's the 2nd how should I proceed to substitute it?
Thank you very much ^^
