[kalilinux25]

Hi a very bad ay to me, I have this board I accidentaly poke the metal twizzet to its lvds cable then the unit turn off , I plugg the charger its causing heat on the RT8249CGQW , I tried removing it and plugging the unit , and check the voltage on the ,mosfet 8v0405 going to the resistor shown in the picture it shows 1v reading , I have someone can read and help me, beacuse I cant find any schematic for this new board model.

I already tried to change the RT8249CGQW but no power consumption , I ve check the Pin 12 of the RT8249CGQW it has 19v , what maybe the other thing to look out?

PLUG IN but no voltage on the neigboring coil of the RT8249CGQW

PIn 3/6/13/20 Voltage?? Resistance on PIN3/13??

Btw, you apllied power while RT8249 IC was removed?? If yes, then perhaps you have killed the mb for sure.

I tried plugging the power right now the RT8249CGQW is gtetting hot again,
