You are not alone !
I think the problem was that I plugged in the USB and battery at the same time.
I have a standard setup with no jumper and no BEC, only PM.
Everything was working, then I was doing radio and compass calibration and stuff, and was plugging and unplugging stuff as I was switching channels around and stuff, and probably fried it somewhere along there. Not really sure exactly, but I am sure I did something wrong.
So now I have the same problem, It works with USB, it works with BEC, but if I try to use the PM port, it won't work.
Solution:
I wired the PM plug from the module to a ESC wire and plugged it into the input side.
It works now.
Don't know what is wrong but it works now if you want to try that.
When attempting to power via PM, is your green 'Alive' led lit up? If not and if your board lights up like normal when connecting via usb, there is a good chance your PM is defective.
i cant power it through the power wires from the esc. but from the power module. still not powering
