Mysterious mark on laptop screen

6 posts · originally from https://geek.digit.in/community/threads/mysterious-mark-on-laptop-screen.161169/

I've a Dell Vostro 1510 which has a matte screen. I have used collin to clean the screen ever since I have bought it, that will be around 3 yrs and never faced any issues. But now there is a spot on the screen which is not going away. I have attached a pic, please help me out guys.

Collin doesn't help? Probably a mark inside the screen. Your best bet is service centre IMO

+1. If collin doesn't clean it, then it has to be below the screen.

Any theories as to how the spot appeared from inside surface of the screen?

Maybe damage?
