S7 Edge: No signs of booting - draws some power

Have two G935F phones that are both hard bricked. One draws 0.05mA when plugged in or whenever the USB cable is connected.

The other one does similar but sometimes draws around 0.30mA.

Attempted to use freeze spray on the latter to identify a short and it all evaporates at the same time.

Stereo Microscope inspection and shield removal reveals nothing out of the ordinary.

I have ZXW Tools

My question is where for Galaxy phone do you begin with these board problems, battery, screen and connector ports also replaced.

I’m familiar with iDevices a lot more so any help and advice would be really appreciated.

Got to the bottom of these and thought I’d share the knowledge.

One phone had a short on "C3 image processor / Samsung S2MPB02 PMIC" (VDD_COMP_CORE_0P8) I didn’t think the caps looked bad so I removed the IC itself and the short went away, the device booted again with full image only camera not working, data is all fine though which was the main concern.

The other phone however was not solvable. a full short to ground was found on VDD_0P8_CP by comparing board values. Two caps and one filter removed for this small line and short still present. Lower bigger PMIC removed and short still present. The only place left is the CPU, I had to call this one a day because replacing the CPU is out of my depths (even then it may be unique with the hardware encryption.
