MSI MS-16J9 - Not turning on, no shorts found

[Alecs25]

Hello Mon2, thanks for your contribution. I have some basic knowledge so i understand what you are saying and it's very logical, however i don't know how to proceed further.

The only thing i see is that EC_PCH_PWROK is missing, but should be pulsing…? I don't really understand what is this signal, EC monitors PCH_PWROK? It's a feedback?

If i understood correctly, if this signal is missing, all the other signal below will be missing too

For the sake of knowing, H_PWRGD can be measured, need to remove glue from the side of CPU.

It's measuring 0.04v

I don't know what this signal does
