Re: MSI GE72 2QC Schematic plz

At the beginning, I connected the ground probe and measured all the pins in turn. Only Pin DATE- has low impedance. This damage is on the motherboard but I don't know what could be damaged. is the bridge or is there a system in front of the bridge that protects the bridge has been damaged.

Re: MSI GE72 2QC Schematic plz

Just change the bridge. What did you bind to this port? Are the others working for you? If yes, then leave him alone.
