Hardware Nintendo Switch Water Damadged

[Mattarba]

Hello friends,i took my nephew’s nintendo switch ,Which was damaged by wather.

It’s bricked,and doesn’t turns on.

i’m testing motherboard and Found capacitors shorted next to the IC Chip

capacitors Near USB power IC are shorted too and Half a coil is working far right

Then i notice that there are dust traces behind the battery Connector (probably an explosion???)
After desoldering rectangular USB Chi P13USB ,All shorts were disappeared !

I REPLACED the P13USB and nothing happens,My nintendo switch doesn't turns on ...

TESTPOINTS are ok and my battery voltage is 3.75V

battery is seems to be charging

I want to clear the situation ,but i’m a little bit worried about the dusted part of the board…

the name of the dusted semi-conductor is A MAX 17055 it’s a gauge fuel which operate for the battery
is it the faulty part maybe?
Can i have your experimented advices please ? the component far right the MAX17050 is continus and shorted to ground...is it a fuse or a resistor?

Thank you

Hello Mattarba,

I've worked on a few that had water damage and those that had the same problems that you identified above have damaged CPU and will never work again. Sorry for the bad news... At least you know not to waste any more time on it. You could sell it for parts though.

Good luck

I'm sure he moved on, it was 2 years ago already
