Just wanted to introduce myself. For work, i am an electrician. For fun, I've played around with pcbs, electronics, microcontrollers and programming for some years now, replaced a few bad caps over the years. Looking to learn more about board level diagnostics and repair on computers.

L7310 : ~8ohms

to ground.

This screenshot shows these on the board top down in same order.(the text is small but its the 5 bigger squares next to the CPU/ram slot) Is this a shorted CPU? Do i need to desolder these coils and check resistance?...

I am trying to troubleshoot my 2018 Mac Mini. It all of a sudden would not respond/wake up. So i turned it off and turned it back on. When I power it up, the fan blasts hard for a second, then shuts off, power light may go off, then back on, sometimes blasting the fan again. It does this a few times then eventually(sometimes) the power light stays on and the fan runs at a normal speed, but with no HDMI/display. Nothing ever shows up on the display.(no sound, no chime, checked wifi router to see if it trys to connect, which it does not)

I have the Mac Mini completely disassembled...
