My brother's 3DS top screen suddenly got messed up for an unknown reason, he tells me he didn't touch it for some time so I just have to believe him for now. This is how the screen looks when I start up the 3DS: I opened up the 3DS to check if I could see any damage to the screen it cable but everything seemed fine. I am thinking of replacing the LCD Panel if that's the issue but I'm not 100% sure that the screen is the problem. There's no warranty on the 3DS anymore and sending it to Nintendo for repair would be too expensive. Did anyone else have a similar problem like this or does someone know what it is?
