DA0BKXMB8D0 rev D shorted 1.8V

[kubica]

Hi,
I have a DA0BKXMB8D0 rev D motherboard.
There is a short circuit on the 1.8V line.
During the short-circuit test, absolutely nothing getting hot, board take 3A.
What can I do now?

With no power to the board, what is the exact resistance to ground of the 1v8 line? If the board is consuming 3A then someone is getting hot. Is the CPU without a heatsink?

You are injecting a voltage onto the 1v8 line?

What's the exact resistance to GND on 1.8V rail?

This is an amd platform and a short on 1.8V rail is almost a sure indication of shorted cpu.

With no power resistance to ground of the 1.8V line is 0.1ohm. I removed a heatsink and injecting a voltage to spi vcc leg.
My thermal camera is cheap and I guess it doesn't see that the ryzen is heating up.
