Hi guys,

By mistake I touched the power cable of the motherboard gpu and turned off the equipment and did not turn on again. Checking there is a component that takes too much temperature, I replaced it but it remained the same.

Video test continuity and voltage:

Does anyone have the schematic of motherboard to verify?

Thanks in advanced

Hi ,
very hard to understand what’s going on apart from the fact that you need a board view/schematic .

check here for schematic + boardview :

This is the original source:

It has an annoying survey I couldn’t get the file , hope it works for you :)

Hola ,
Es muy difícil entender lo que está sucediendo, aparte del hecho de que necesita una vista de tablero / esquema.

verifique aquí el esquema + vista de tablero:

I really wish I could help you. I watched your video and your kid sounds like my kid. I ran to the room to make sure he was ok lol.. still sleeping..

Hopefully its an easy fix! To me it seems pretty complicated.. but if you replaced a component and it failed again that would be a cascading failure right? Gotta go down the line?
