F16V4 Expansion Board Half of the board stop lighting up.

So after not using my mega tree setup for a couple week, I turn it on and half of one my f16v4 expansion board fuse doesn't light up, the power supply into it is light up.  So where do I even start?   Is it worth pulling every fuse and checking it?  All the connection seems tight.

My setup is 6 power supplies and One main f16v4 and two expansion.  3 power supplies to the left and 3 to the right.   Everything else works.

sounds like one of your power supplies stopped working

Measure power starting at PSU and working your way out.

Could be as simple as a loose wire (between the power supply and the controller).  But I agree to check the voltage at the PS to make sure it hasn't gone belly-up.

Thanks everyone! Guess that's what I be doing next weekend.   Hope that's it, well hope it's a loose wire first.
