Hello, I have an EDM-10 board .
When I press the power button, the PS5 beeps once and the blue LED turns on. After a short time, the console shuts down again.
Some power-on voltages are missing; please see the measurements below.
When I press the power button, only the SSD controller and the Southbridge get warm, as seen with an thermal cam.
The power-up sequence appears to be normal: current draw first rises to about 320 mA, then drops to around 7 mA.

Any ideas on what to check? I haven't found any shorts.

thanks
