Hi lewis haywar,

Try to replace the LCD inverter in your laptop. Most common issues on LCD are due to failing LCD inverter. It fails more often than LCD cable or LCD backlight does.

Please let me know if this solution helped to resolve your issue.

You should try the cheapest solution first. Replace the LCD cable. These should be easy to find on ebay and amazon. My guess is there is a short in the cable.

A thin line across teh screen is an indicator that the LCD is bad. There's not anything short of replacing the screen that will resolve this issue.

Dell Vostro 1400 LCD Showing Black Screen

If you connected the laptop to an external monitor via VGA and the display, then it is not "an NVIDIA GPU defect" .

The video chipset connected to the LCD screen is the same connected to the external VGA port, and is working fine since picture is OK on monitor.

More likely the problem is either LCD ribbon cable, or LCD display, the fact that the backlight is working means that the inverter is also working.

Inspiron 1150 lines on screeN problem.

Connect an external monitor to the laptop and see if it also has the vertical lines. If the external monitor looks fine, then your laptop’s LCD display panel is bad. If the monitor has the vertical lines displayed on it, then your graphics card or motherboard is bad.

Not a typical backlight issue


You can check the brightness with AC in the BIOS and match it with running in battery or else, when you plug the ac adapter, the lcd goes dim, press and hold the FN buttong and tap the up arrow then reboot and try to see if it will still do it. But still the best way to do it is going to the BIOS by pressing F2 at the Dell logo startup.

Hope this helps!
