I figured I would ask here since I haven't found a firm answer anywhere else. I have a HP dv6-7000 laptop and have recently been having a thin, light gray, vertical line popping up on the middle of my screen. The line only appears once in a while and when it does, the time varies (sometimes right after startup, sometimes when the laptop has been on for a while). If the laptop is restarted it does show on the loading screen. I never plugged in an external monitor to see if the problem persisted. Although pressing the screen is not recommended, if I lightly rub my finger down the line it does disappear. I have never dropped the laptop nor banged the lid on anything.
Beginning of dead pixels? Loose connector? Something else?
