Hi,
On Mosfet Q7002, is missing rail PWR_SL1_F_GATE 3,3V. So there is no voltage on the Board. That lead me to U3601 IT8528, and i found a short on +3V_EC.
I injected some voltage on that rail, then checked with thermal camera, and the IC U3601 was warming up instantaneous.
With the IC in place, the rail have 0,002 of voltage drop in diode mode. And there is no voltage present.
Without the IC, the voltage is present 3,3V. And if a measure in diode mode, the value is 0,080. Seems to low for that rail.
Anyone have that values, for reference?
My bet goes to U3601 faulty. I already tested with another IC, and same result (maybe the new IC was also damaged).
