None of the blue LEDs are flashing, they are solid.

Just to clarify, from top to bottom = signal, power, ground?.... which is the opposite of how my AR8000 servo pins are (just double checking)

Yes, I am connected to channels 1-4 on this one.

GND = bottom
5v = midle

sig = top

Yes, that's what I've got.

So the solid blue LED means no signal from radio, right?

....which just boggles me even more.

correct. try power cycleing the board etc. you are powering the servo rail arn't you?
usb does not feed the rc receiver on newer boards

Power cycle didn't help.

Yes, powering the rail on the 3rd output, using ESC connected to LiPo.

This seems like the same problem I'm having. And like you, I'm very nervous...

Check out my post(link below), let me know if it's similar

Kind of... my lights are on, but it's obvious I'm not getting a signal from the Rx, and my ESCs are calibrated.

The power rails are working so nothing is too burned up.... really scratching my head at this one.

Ya, I'm very lost...my power rail works and will power the Rx on any of the outputs. I can even control the motors, however, not as you'd expect. ( you can see that in the video)

 

I just don't understand why the lights aren't on. I'm worried I fried something and that i'll have to go spend more to get another APM.

Solved!

Good news: I swapped out the Rx with another, and it now works like a dream.

Bad news: The Rx that I ruined was my brand new AR8000. Good thing I bought the Dx8 last week in the first batch that now comes with 2 Rx's. Still a bummer though.

So if anyone is experiencing the same issue, try a different Rx. See, I told you this would be an easy one. :)

If you have nothing plugged in to your board except for USB power, do you get the MUX & PPM lights to turn on, on the APM?
