My Dell started turning red where the black colors should be. It also has a few faint blue vertical lines here and there across the screen. It was that I could open the laptop and fiddle with the position ( up or down a bit) and the discoloration would go away. Poof normal screen.
Now it is like this all the time with no ability to reposition it for a clear screen.
If anyone has suggestions I would greatly appreciate it.
Also I am capable of following specific directions however it is quite hard to find videos for the 15 3521 touch screen.
