PS4 ADP-240CR fast shutdown

[tikyucnan]

We repaired an ADP-240CR that was not producing 12V properly.
DDA001AG and 1608B were broken, so they were replaced and 12V came out normally, but when connected to the main unit and turned on, it immediately shuts down.
Then 5V is not output and the power supply locks up.
When the power cable is disconnected and reconnected, the lock is released.
I have seen the locking symptom when there is something wrong with the 1608B, so I replaced it with another 1608B, but the situation remains the same.

I transplanted major ICs such as DDA001AG, DAS001, 1608B, DNP012A, DNP015, and DAS001 to the donor side and it worked without any problem.
I put it back to the original ADP-240CR again, but it is still the same.
When I connect a fan for PC case to the 12V line without connecting to the main unit and short-circuit 5VSTB, it works without any problem.
Other than that, when I connect the power cable with the 5VSTB short-circuited, the fan turns for a moment and the power supply is locked.
If you connect the power cable, wait a while, and then short-circuit the 5VSTB, the fan for the PC case will turn normally.

I replaced the 100uf and 150uf capacitors for 450V because I felt like they were locked up when current suddenly flows through them, but it has no effect.
Is there any other place I should check?

Did you check optocouplers?

I forgot to tell you that I replaced the optocouplers.
All optocouplers have been replaced.
D101(STPS20H100C) was the cause.
I noticed that if I connect only the 5V line to the PS4 without the 12V line connected and turn the power on, the 5V line is lost and the power supply is locked.
I thought there was something wrong with the line that was generating the 5V, so I compared D101 with the donor and the values were different, so I replaced it.
The result was a great success.

Great! Good job mate!
