Hello, good day everyone I have an Xbox 360 E, Winchester, the power button turns green for a second and then turns off

I already measured 3.3V and it intermittently switches between 5V and 0V at its output.

MOSFETs 05C1 and O6C1 (4C55N) also have continuity and low resistance between D and S.

Any idea what the real problem is? I would hope it's just the 3.3V regulator that's faulty.

Thanks for the help!
