PS5 EDM-031 . No beep - No Light - No UART!

Boot sequence 0.009 A only
Fuses are OK
NO UART…but 3.3v on RX and TX
No short around SB
Standby voltage seems ok

@Calvin help!

Missing standby 5V on Dialog!

Where it is generated?

The 5V_EVER line is powered by the left mosfet. Left side 12V input and right side 5V output.
Downstream are the F7001, F7002 and F7003 fuses.
