I have trouble finding the short on a 820-2879-B board. Resistance to ground on PPBUS_G3H is 11 ohm. I removed F7040, short is on the side of pin 2.
A bit of (sugar-ish) liquid damage on U7500, C6960 and around R7400. Cleaned with IPA, but 11 ohm short remains.
Have put 0.8V directly on PPBUS_G3H, takes about 0.37A. This 0.3W is too little heat to actually warm up the short I guess, since I can't find it with putting some IPA on certain components and actually feeling the heat. Not sure if I want to increase the voltage, since I know you can mess up the CPU while doing that.
Before randomly removing components directly connected to PPBUS_G3H, and tips on where to look for?
