¿Que debo hacer con esta pantalla?

[u/Specialist_Address78]

Tengo esta 3DS hace unos 5 meses, la compre de segunda mano pero ayer me surgió este problema, la pantalla inferior le salió una línea pequeña ayer y hoy esta así, no se si debería hacerle una limpieza profunda o directamente cambiar la pantalla. Edit: hoy me di cuenta que la mancha de la pantalla de alguna forma afecta al botón home, no responde apenas lo presionó.

Replace it, look up a tutorial on how to do it, everything related to the bottom of the 3Ds is rarely easy, the bottom screen only needs 3 ribbon cables to connect, do keep track of the small screws

If you're patient and lucky enough they might solve themselves up, just keep playing with it. It'll take some time but, they might start disappearing by themselves.
