ANy chance during soldering or handeling of the board has it gotten bent ever so slightly?? maybe a circuit path was snaped?
Check SJ1, as instructed in the Troubleshooting Guide.
thanks Chris and Jeffrey.
I now have restored 5 volts to Rx and to APM rail. My radio has a link with the Rx because when i swap to a servo and move the sticks, the servo arm moves as it should.
When i attach flight battery with radio on green light goes solid (stable flight), Rx lights on for link, solid blue lights on both red APM and blue APM - i think one is supposed to blink rapidly (from trouble shooting page) ESC's are beeping continuously and i can not arm motors. I have tried lowering throttle trim but no luck.
When in the configuratior i can't calibrate my radio because no movements are detected.
After disconnecting everything but the Rx I have this light flashing on the board (see photo) when in the configurator.
I think my board died.
