Test for Dead MacMini Logic Board?

Hi,

I have a Late 2012 A1347 Mac Mini. Doesn’t power up, no lights, no fan. I checked the power supply and getting 12v from the left pins.

Is there anything else before assuming this is a dead logic board ?

I have a DMM and can check voltages on the logic board, but not sure what I can check.

Would hate to spend $300 for a new board, only to find out it is something else, and still have a dead, nearly decade old machine.

No pops or anything unusual when was last shut down. No burned or smells from board. Nothing visually obvious on the board.
