LCD Stain in my MacBook Pro 13" Late 2011
I got a second-hand MacBook Pro 13” Late 2011 from a friend. I previously changed its battery, RAM, and HDD to SSD.
The display has stains inside which I believe it’s under the glass. It has been like this when I got it. I just wanted your help if you could help me diagnose and which I should fix. I have never removed the glass and I just removed the screen protector which dismissed my early hunch that it may be due to that.
