I have an HP Pavilion N5425 laptop, 14.1" LCD TFT (Toshiba) that works fine but 1 complaint: About 1/4 way across the screen (from left to right) there is a thin blue line running from top to bottom. It started very faintly but grew continually worse and is now a "permanent" feature. The screen and laptop are fine otherwise, and I've been able to check all internal connections and and component seating. But the this hasn't corrected the problem. I can replace any peice, but what part is it? Screen? Cable? Video Card? When I change resolutions, the line stays in the exact same place on the screen. When I unplug the cable from back of the screen (leaving the invertor connected) the screen remains on and show a plain white field with no blue line. Using the video-out from the laptop, the line does not appear when hooked to a TVs video-in. (I do not have a proper monitor to try this with.) Gently moving the cable seems to have no effect. But there is a good length of it held still under the power-button pcb when the laptop is re-assembled enough to turn it on. Anyone have any experience like this and have an idea as to which part to replace? Any more suggestions to try? Thanks!
