820-00163 green light no power


New member
Hi guys this time I have a 820-00163 board with no water damage or corrosion, checking all rails I found a 3v3_S0 pulsing with oscilloscope, which means I possibly have a short on S0. in the schematic I only see a few mentioned where I should start

Probably more power rails pulsing.
Should find the one which not and check for short there.

Steady 3V3_S5/SUS?
Try to start in SMC bypass mode.
