Horizontal Green Line

HP Recommended
Microsoft Windows 10 (64-bit)


Two fix horizontal green light has sudenly appeared on the screen of my HP notebook.


I have tried to restart my computer, but it is still there.

And when i do a print screen, it does not appear.


My notebook is relatively new, but I made a professional clean-up last week from an authorized shop.


I found the issue after it, I checked with the BIOS screen, it still appears, Also I doubt if it could be a issue with the ribbon cable. Perhaps it hasn't well connected.


Any idea on how to check what this is and what to do about it ?


Many thanks.
