Yesterday I bought a NDSL and a DSTT! OHHHHHHH!I'm so excited! But thereis a problem with my NDSL. I found a dark place on my NDSL screen, it made me uncomfortable, I want to fix it, but I don't know if it can be fixed. If it can be fixed, how much will it take? If it can not be fixed,what should I do? I NEED YOUR HELP!
