Hi guys,
I have this junky 3DS XL 2012 model, I guess it suffered water damage (or coffee spill who knows).
Battery was puffed up and I've found a brown rusty trail around battery like it leaked something.
The unit has been previously opened because of shoulder button cables ripped, I don't know if to dry it or something, by the way the board didn't have bad corrosion, only a tiny bit on headphone jack soldering points and the positive battery lead soldering point. Contacts are good.
I cleaned it properly and reflowed those joints.
Now the behaviour.
I don't have an oem battery to test but I hooked up to my bench power supply with alligator clips on battery contacts and it basically do nothing.
I checked fuses and are ok. If I put a charger it will light up the orange led for some seconds and then shut off.
I tried with a lion battery (3pin, same layout as its original one) and it does the same.
Checked with multimeter power button and itworks ok.
With battery connected and a multimeter I see correct voltage flowing first and second fuse.
I searched a lot but didnt found any answer or hint, all interesting threads are about NEW 3DS xl which have different board and components layout.
No info on the 3DSXL first version.
I have very good soldering skilks, and I can use a hot air rework station too..
May it be the power regulator? Anyone can address it on the board?
If someone would be so kind to help me..
I am doing it to learn something new, to improve.. so I am not interested in buy a new board (even tho I'd need to check other components too before doing it). If I manage to repair the board I would be happy if not.. it goes into the trash.
My point is try my best at it and learn something new.
Thanks!
