PS3 CECH-4004A: No Power, LED Off - APS-330 Power Supply, Voltage Check & Potential Solutions

Hello,
the console was connected to the network all the time and the red diode was off, so I disconnected the power and reconnected it.
It started and I started the game, after a few minutes it turned off and it does not respond to the on button at all, no LEDs are on.
I read on the forum that this may be a problem with the power supply. So I took it apart and checked the power supply, the APS-330 sits in it.
On a small connector with a disconnected plug there is 1-5.5V 2-0V 3-0V 4-4.6V on the pins. After connecting the plug to the board, the voltages remain, and when I disconnect the 230V mains cable and plug it back in, the measurement on the pins is 0V. I do not have a spare power supply to check the motherboard.
Has anyone had a similar problem?
Please help.

Check the power supply of the wifi module if there is no short circuit
best regards

Thanks for the answer.
How can I check it? Can it be detached or detached?

Resistance meter or diode test. to the photo arrows and to the minus.

best regards

Short-circuit test on the power supply whether it turns on

Which pins to connect to make the power supply stand up?

Console put into service. Replaced main board.
