If you take a look into schematic, you’ll see that F2 is connected to 5V rail, and EN of U7 to 3.3V rail. If they are both below 1V then your PSU/regulators are not behaving correctly. I’d start by checking 5V rail since it drives 3.3V regulator – maybe D5 is installed wrong way (you should measure 5V over it even when power is switched off) or you have a short somewhere.
