I not know what have done the customer, but signal of drop down in the sx side, near of Audio Jack there are, not see any signal of water in the main board, no oxid, no part water damaged.

I see clean battery connector, where should I resolder, and the Power IC is this?:



Pardon but if i enter whith JIG and power external not wok, right?

@:SARCAR:,

After i've cecked all voltage in Gazoo and IC signed, have reflow a small the IC, when had connected only Original f/bus cable in contact battery and Jig of pcb, other RJ45 to Atf Box, when improvvise i can see that this DEAD N8 was connecting in f/bus.

Have done all test sw, reflashed phone, erase all first, and also USB cable was working.

In the first time, i had received , from self test, 4 errores:

1) camera
2) Lcd
3) Touch
4) KELVIN CAPACITOR , minor!!

Ok, i understand errores 1, 2 and 3 becouse phone was only whith pcb and any more, after i've assemble it no more these 3 errores.

Only this Error to point 4) KELVIN CAPACITOR is always minor from test, What's this?, phone is working normal now, but i think alls problems was be from this component, please can do see where is this in pictures, and or goes changed obbligatory, many thankx
