Chosen Solution
I got water damaged(light water spill inside a backpack, near ABXY keys) 3DS XL for repair or to sell as parts. Ofc I want to do the former. It does not turn on, nor charge, and after visual inspection i found 2 obliviously fried components: Charging IC (CKP, which is apparently Texas Instruments bq24072)Element DA4 near Wi-Fi card, marked D60(still unknown what it is, probably some LDO) Picture of the place(metal sheild that should be under Wi-Fi board is removed):
Both fuses are not blown by the way. So questions are: What is element DA4 and where can i get one aside from other 3DS?How to diagnose further to make sure i won’t burn these components or anything else right after replacement? Is nintendo boards have elements glued to? I cant lift anything from board using hot air gun.
The BQ24072 should be easy to source (http://ca.mouser.com/Texas-Instruments/S...). What is the marking on DA3? Chances are they are identical or complimentary. I’m not an expert on Gameboys so I’m just trying to help here. SMD marking codes are not an exact science and they are not unique. As best as I can tell, they appear to be TVS diodes in SOT-5 packages. I haven’t found any schematics on the web. Donor boards might be the best approach here.
