Problems with kk mini board

[NuttyGeezer]

I am having some problems with my kk mini board, which has worked previously but is now behaving strangely. I switched it on, did an ACC calibration and a receiver test, where it said everything was working fine. I then armed it and throttled up, but after around 3 seconds the motors stopped spinning even though it was still armed and I hadn't changed the throttle stick. I then disarmed it, and on the screen it said "error - no yaw input". I know this usually means that it is not connected to the receiver, so I did another receiver test, which again said everything was working fine. Is there anything I can do to stop this? Thank you for any help

Was there a crash recently? A factory reset can fix some stuff. Or an update.

I haven't crashed, but I will try both tomorrow to see if they work, thank you for the suggestion
