i have an hp pavilion dv9207us notebook pc. Just a couple of days ago, a horizontal line has appeared just below the middle of my display. I know they are not dead pixels, because they change colors, so i don't know what to do. i know it is not my GPU (nvidia geforce go 7600), because i connected my laptop to an external display via VGA cable, and the external display did not have a horizontal line through it. It has to be my laptop display. I have not dropped the notebook, i have taken good care of it. The line randomly appeared, and i am out of my warranty;i really need help. (Running Vista 32bit) I cannot replace the display, because it would be smarter to purchase a new notebook.
