I promise you it's ohms, not kiloohms or megaohms. 0.8 ohms. -
.8 ohmsLeave a comment:

There's no current draw and no heat on the thermal camera, even after slowly increasing the voltage, and installing the replacement mosfets....Leave a comment:

Like I said above, the drainLeave a comment:

I thought i had posted in that thread, i'm not sure how this conversation wound up as a DM.
I have some replacemenet MOSFETs on the way, i'm just worried if there's a short to ground on one of them. It looks like there's supposed to be 20v there.Leave a comment:

It's the one labelled P039, further from DCIN, not sure which exact purpose it serves in the circuit. It's measuring 0.8~1.8ohm. At PL7, which is below the GPU and to the left of the CPU, it's 2.2ohm to ground, but the smaller PL5 and PL6 above the CPU are open with respect to ground.
It's a shame with all these fuses on the board none of them blew to protect the rest of the circuit, but I guess there's only so much you can do when it's water damage.
Thanks for your prompt reply

betty r6_mb
I have a betty r6_mb with a similar short to ground at the drain of the left mosfet, even after removing both. It stopped working after water ingress, and there are a few minor rust spots on some of the caps. Do I need a multimeter that supports capacitance to confirm which specific caps are shorted? Even if the shorted cap is identifiable, is there a way to identify the expected value without the schematic?...
