Hi can someone help me diagnose further than I have. I am confused why I am missing 1.8v + 3.3v rails around the hdmi.
PS5 has 12v, 5, 3.3v 1.8v and various other rails but is unable to complete post. No blown fuses, no shorted rails, no visual damage, some work has been done to the board previously.
front hdmi - missing multiple 1.8v and 3.3v
rear hdmi - again missing 1.8v, 3.3v
top left southbridge - these standby voltages are missing
lower left southbridge - weird, reading 0.2v but should be 0v standby and very bottom 3.254v expected but reading 0.995v
@jkyoho sorry to summon you, do you see anything here I am missing?
I have tested multiple step down ICs PMICs around the board, all are testing ok, inline with known good standby voltages from a working board. I do not understand the logic of this hdmi ic circuit.
