Black Vertical Line on my Samsung Curve Monitor

Hi, I was just moving my monitor everything done carefully but then I saw this Think Blue Line in the middle of the screen so I googled it and found out its an easy fix so I open my monitor panel and did exactly what I saw on a tutorial on how to fix it. But that didnt work instead i got this Dark Black Vertical Line on the left side of my panel. so now i have no idea what had happend and now how is it going to fix. does it even worth fixing or am i toast.

The Video is the one which i had before and now the one in the picture shows the current status please help.

MY Monitor Model Number is C32HG70 Curve Monitor
