Hi there,
I have a gigabyte z390 ultra durable motherboard which is completely dead.
It's new, it came dead on arrival... it has no warranty
You plug in atx+12v connectors and short the power on pins but nothing happens...
I have 3.3v on poweron pin.
If i short the atx poweron pin on psu connector while is connected to motherboard, cpu led comes on... nothing else, no illumination pcb leds come on.
If i do the same on a similar good known board (gigabyte z370ud) cpu led comes on and also the illumination pcb leds power on...
I have some electronics skills, it's not a problem for me to replace any component on this board if needed (except chipset ic)
First of all it will be nice to find schematics/boardview but i doubt someone has.
Thanks!
