Msi Gp76 20V short Rail

[brain123]

I have a Msi Gp76 mainborad here that cannot be switched on."20V rail has a short circuit. One of the mosfets from the graphics card burned out and was unsoldered. The board is still hot without the mosfet.

What could be the problem?

Remove all power. Meter in resistance mode. What is the resistance to ground?

Post or link the schematic and boardview files.

Unfortunately I didn't find any schematic or view.

At 0R3 ohms to ground, this could be the GROUND pad on each device. Post the top side markings of the mosfets that were present on the logic board.
