SLC2 FREE 2 not booting

Hello, i bought the SLC2 FREE 2, after doing the wiring and soldering, the screen is not switching on, i check the continuity and solders, nothing seems wrong, i do get 12v coming trough the 4pins molex but nothing after, i don’t know where to check from there.
Here’s a few pictures


Can you test the resistance between 5v and ground pins and post your result?

i wasn’t sure wich pin you were talking so i took both:

may i up this topic?

At the bottom on the board there are unpopulated pin headers marked “5v” and “Gnd” please test the resistance between those two points.
