Hi, so my new 3DS just died on me. It won't charge, or power on or anything, even LED lights won't come on. I opened it up and the board is basically pristine, no water damage at all. I know it's not the battery since I just changed it, or the charger since it works on my other 3DSs, I even Goh the new charging doc and no results. I'm just really confoosed Btw I have some basic knowledge on soldering too, but the thing is I just can't locate the problem. Help!
