If your laptop screen starts to behave oddly it’s very important to have it looked at. Odd behaviour can include colours looking washed out, lines through the screen, edges or corners looking like they have water inside them, etc.
Bring your laptop to us and we’ll let you know if it can be repaired, or if it requires a replacement. Sorry to say not many screen issues can be easily repaired because of the nature of how screens are built, so often the only answer is a replacement screen.
We can advise on this and can order the necessary replacement for you, then install it and test it is fully functioning.
