IOC stopped working

    I have a first-gen Phantom sn: 8e3d8c9d466f7a356a25a161644bdfcc / firmware version 4.02.

    Recently I traveled from California to Hawaii and noticed that the compass initially recalibrated and the Phantom flew properly. On the second flight I got a compass error and it would not recalibrate. The Phantom would fly but I could not engage IOC.

    When I returned to CA, I ran NAZA-M V2 and checked the readings. When I move the transmitter IOC switch to CL, X2 goes from 796 to –5, HL goes to –821, so the switch is working but when I fly it and switch to either CL or HL, I do not see a yellow light and the IOC (HL and CL) does not activate.

    Any ideas would be appreciated....
