connect with a external monitor & see whether you get the same lines,if not then its LCD problem. Normally there are so many thin wire lines is built across the screen,sometimes you can see it clearly in the white pages,so try those Try also Updating BIOS & Video driver.

Laptop problem


Reseat the video cable connection under the keyboard, and see if the lines go away. If not, connect an external monitor, see if the lines show there. If the lines do not appear on the external monitor, then replace the LCD. If they do appear on the external monitor, replace the motherboard

Vertical lines in my laptop screen


Try connecting an external monitor to the Dell Inspiron 9300 and see if the vertical line is also present on the monitor. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor also displays the vertical line, then your problem is with either the video card or motherboard located inside your laptop.
Not sure if the Compaq Presario has an external monitor plug, but if it does the above procedure can be applied to that one as well.

Vertical lines in my laptop screen


There can be 3 possible reasons for this
1)Screen connector cable is loose. You can try to re-seat it and see if works.
2)display card problem. Connect your laptop to an external monitor and see if the problem persists. If it does not then
3)You will need to get a replacement LCD screen.
Hope this helps!
