How to do if your multiplexer is dead, not powering up via any adapter cable when using MB SD connect c4 testing

Please Kindly Notice: 

TRY AT YOUR OEWN RISK!

First open the MB SD C4 main unit. Slide PCB out a little bit, from the connector side, so you can see the units buttons wiring. Carefully pry the lock out & up, after that you can pull the wiring and PCB out.

Then Open 4 Main PCB screws, Carefully wiggle the PCB off from another, it might be pretty tight, so carefully, side from side!

You can use multi-meter to see if they work, usually the LAN connector side 5A is burnt. So desolder the broken one, install new & enjoy your powering up mux again!
