Hi all,
I just bought a used ASRock AB350 Gaming-ITX/ac Fatal1ty, as I always wanted a small pc, the previous owner said that the board was updated to the latest BIOS (10.50) using a Ryzen 1600x but after checking it the board stopped working as he wasn't able to do the POST anymore.
I bought it and used a Ryzen 5 3600x but the issue remains, I later discovered that the 1.2V is missing but the MOSFET correctly recive 12v.
Unfortunately my cheap multimiter probes slipped and shorted something around the PWM chip (model 95712hrz w712bmp) causing the 12V to short directly to GND (no smoke detected but a burnt scent was present )
I'm in search for a schematics/ boardview that can help me diagnose the short (I caused) and the fault with the PWM/MOSFET not creating the 1.2V for teh CPU.
I have found some similar threads on the website already but are related to BIOS request or I am not able to download the provided documentation.
Many thanks.
