Laptop Screen shows Pink/Green Horizontal Lines at the TOP.

Hi @kk8 ,

Connect an external monitor (TV?) to the laptop’s HDMI port and check if its display is OK. Don’t forget to press the appropriate keys to extend the video to the external display

If the external display is OK then the problem is either the video cable (eDP cable) between the motherboard and the LCD panel or more likely the LCD panel is faulty.

Here’s the owner manual for the laptop.

Go to p.38 to view the necessary pre-requisite steps and then the procedure to remove/replace the display assembly.

Doing this will give access to the video cable so that it can be inspected for any damage, loose etc and also the LCD unit. (see p.43)

If it is determined that the LCD panel is faulty it will have to be replaced as it cannot be repaired. Replacement screens are available online. Just search for Dell Vostro 3568 LCD screen to get results for suppliers that suit you best. Sometimes the Dell part number can be found on the back of the LCD unit if you wish to verify that you’re ordering the correct one.
