So I remember this happening to my house's desktop computer's monitor years ago and now it's happening to my laptop's screen. I have a pixelated line down my screen. I remember it almost completely engulfing the old monitor as more and more lines started appearing. So far mine is just this one line, and it's not there 24/7 but lately it's been appearing more often and staying for a longer period of time.

I've already tried rubbing the screen softly and using a stuck pixel finder. and it's been semi-successful in that I can get it to disappear for either a few minutes or hours but it keeps coming back. Do I have any other possible options before I have to resort to sending it in to get it's screen replaced?
