Friend's New 3DS XL has water damage but no corrosion
My friend has a New 3DS XL that's bottom half had came in contact with water a few years ago.
The screen used to turn on after the damage but now does not after she gave it to someone to take a look at it.
It is missing the battery. She is trying to fix it and opened it up and noticed the water contact sticker was pink although there was no corrosion.
Is this an issue with the missing battery or something else?
