White lines when screen is off/black?

[GavMorgan]

Hi, I have vertical lines on my screen when the screen is off. They don't show when the screen is on as it's not the LCD but more like smudge lines and won't wipe off, anybody have any ideas please???

That sounds strange, @GavMorgan ! Can you provide us with a photo of this? Then we can understand what is happening.

Have you got a screen protector?
