laptop display issue -horizontal lines near bottom
Posted on 2013-09-20
I have a Dell Latitude E5400 with horizontal lines across the bottom of the screen. They cover approximately the area of the taskbar . Issue has been present for a while and user has been working around it. At one point the bottom of the screen may have been mirroring on the top of the screen. The laptop is not under warranty.
I have not booted to bios to see if the issue is present before booting into windows. It is not present when looking at the screen through remote connection. I am fairly certain that I updated the video drivers earlier this year after the problem was initially reported, and it did not resolve the issue.
My initial assessment is that it is hardware related, either the display cable, the connection to the display cable, or damage to the display panel.
I do not have access to spare parts for troubleshooting and hesitate to open the case unless I can resolve the issue. Other than re seating the display cable, what else can I do?
