I have a Dell Inspiron 9200. My screen is showing black lines on different spots. They run from top to bottom. There are at least 5 lines. Do I need to replace the screen? Thanks

Yes! but it is a good idea to hook a spare monitor to the video output first to make sure there is no problem, if okay! replace the LCD screen. Go to www.ebay.com Type: make and model of the laptop and refine search to screen, a list of sellers will pop up showing the prices.

you can try to connect an external monitor to your system then toggle FN+f8 if you see the screen good in external monitor it means the graphic card is ok then you have to replace the LCD panel.

there is a loose screw on the screen hinge. you will have to lift the panel at the top by screen. unscrewing any screws that need removing. usually its just the screws on the hinge cover on the outer edge, then tighten the screw with the wire attached to it.
hope this helps

There are only two issues here, one it could be the data cable on the left side of the screen has come loose from the socket on the LCD.....most likely though is your starting to have a cascading screen failure and will need to replace the LCD panel.

Replace the screen, they're not repairable.

lcd sounds like it's dying or possibly cracked somewhere, i recommend replacing it, it's not that difficult

turn off laptop.
press and hold on the D then press Power button.
during the LCD BIST test check if the black line down right side of the screen is visible. if yes LCD needs to be replaced. if not connect your laptop to an external monitor check if the black line display appears to the ext monitor, if yes uninstall / reinstall video driver if fails replace video card or if it is built in replace motherboard.

if no ext monitor available then run PSA (press and hold Fn key then press Power button)

check if the black line is visible. Check also in BIOS is black line is visible, if yes then uninstall reinstall first the video driver if fails replace LCD.

You can reseat the video cable to the video card, and see if that makes any difference.

Also, Connect an external monitor, then press FN+F8 and see if the issue appears on an external screen, If not, then replace the LCD

It could be either of these two:
