Red horizontal line

I have recently aquired an unwanted red line through my screen.  I have replaced the cables tested a diffrent monitor, and even replaced the logic board.  What I'm needing answered is can I send this into dell to get a new screen put into it as I feel that is the problem after trouble shooting it.  I did not purchase this monitor from Dell, I recived it after my work had thrown it out for a blurring issue that is no longer there.  all in all I feel the wires conecting to the LCD are bad or the LCD itself is shot.  however I realy like this monitor and wish to fix it and keep on using it.  Dell ultrasharp 2001FP.
