There are EMI filters on the data lines (USB to south bridge). Check them for continuity. But if both ports don't work, and you have 3.3V on PXGI then the south bridge is bad. -
Does controller works in safe mode? Those power ICs (PXGI right)? Any pins shorted to gnd? Do you have 5V on pins 1-3 and 3.3V on pin 4?...Leave a comment:

AFAIK there's no equivalent for it. Kasynparts shop has them.Leave a comment:

If U12 works, post resistance and voltage of every pin.Leave a comment:

Check all fuses on the motherboard and post HDMI port readings (diode mode).Leave a comment:

Check resistance on this rail. If it's low, inject voltage to see if anything is getting hot. This signal comes from SB I think.Leave a comment:

Yes, missing components in this area could cause the symptoms you described.Leave a comment:

Did you check HDMI port and encoder IC?Leave a comment:

Smaller cap: 1uF 6.3V, bigger one: 10uF 6.3VLeave a comment:

Hi, I have the same issue. Did you solve it?Leave a comment:

Yes, 0402. 10mA could point to SB area (check there for shorts) But first replace the caps, fuse and check power draw again.Leave a comment:

0.3ohm on 1V is good. Did you check the power switch board (voltage, shorts, flex cable etc.)?Leave a comment:
