Before I was at my laptop and suddenly the screen got so colored (see picture), what is the problem and how can I fix it?
Can the screen still show something, or do you only see these colors?
Only the colors
According to the Internet, it would be a hardware fault, for example small, minimal hairline cracks.
Can I fix this hardware problem?
No, because then the display has to be changed? Better you google for this problem. (Galaxi .de)
