Unplug the system, remove the battery and hold the power button for 30 sec. Disconnect and reconnect the LVDS cable from the mainboard and back of the display panel - check if for damage along the conductor and at the connector ends. If it's clearly damaged, replace it. If it's not, then reassemble the system and see if the problem disappears. If it does, you've found the problem. If not, replace the display panel with a new one.
Actually have the same situation. One year old 15R 5521 touch screen laptop with heavy thick vertical lines in display. Tested with an independent monitor; no lines on the independent monitor which indicates either faulty touch screen display or the cable, according to a forum. If anyone knows how to differentiate the two, it would be appreciated. This is my 5th, but will not buy another Dell product
