Hopefully the answer is no..
So, I was trying to understand my radio outputs in QGCS. I had it all connected and working, but the order of the channels were incorrect and the roll channel was registering. I am using a PWM-PPM converter for my A9 radio. Everything was powered up and operating fine. When I disconnected the battery and then reconnected, no more lights on the AQ. {edit} All I did between battery disconnect and reconnect was remove and reinsert the lines from the rx to the ppm converter. Shouldn't have caused any issue {edit} All of the power connections were fine:
Power 14.8v to the AQ
Power 14.8v to the Rx (hitec receivers can take a wide range of voltage inputs)
Power 5v to PWM-PPM converter.
What could have happened? I am scratching my head to think if there is anyway an incorrect voltage got to the board, but I haven't had an issue for the mulitple times i have connected it previously and I tripled checked all of my wiring.
Am I out of luck with a $400 paper weight on my hands? Or are their components that I can look into replacing if it is a power issue because I am not sure what else it could be.
