PS5 No Power after replace HDMI Port

Hello guys, I have a problem!
i have a ps5 here where the customer said it fell down and tore out the hdmi port. so far as good hdmi port and the diode replaced only i get no power on the console. in the power supply I have already exchanged the DAP0531 chip (92 € the chip around 107 $ in the purchase) nevertheless no 12V on the power supply now the question does the power supply only provide power when the console is switched on or always the 12 volts
Thanks very much

As far as I have measured, the power supply always delivers 12V. There are no standby power lines and signal lines between mainboard and power supply which would be (from my point of view) necessary to switch on/off main power.
