    I crashed my DJI Phantom 2 vision and after replacing the blades and putting the battery back in it will no longer fly. When the Transmitter is powered on and then i power up the Phantom i get solid red lights in the rear and no lights in the front. When go i through the start motion on the transmitter they blink and then go solid again. If i turn on the phantom without the transmitter on i get the green/yellow/red cycle. I was advised on this forum to change the Compass and i have done that. also changed the cable to the compass. DJI has told me to send it in but i am really hoping that there is something simple i am missing. I dont have the money right now to send it to DJI.

    Any help or diagnostics would be greatly appreciated.

    Hook to PC ASSISTANT,
    Check your IMU readings:
    Let us know your MOD VALUES?

    IMU= Inertial Measurement Unit
    ( takes readings from ( gyroscope, accelerometer, & compass )
    It takes the values and creates a MOD VALUE for each.

    ( another term for absolute value )

    Basically goes like this:

    Gyroscope SHOULD BE : ( 0.0 - 1.5 )
    Accelerometer SHOULD BE : ( .98 - 1.02 )
    Compass SHOULD BE : ( 750 - 2250 )
    If any numbers above are OFF, perform a ADVANCED IMU CALIBRATION.
    Also run a Tx ( controller ) calibration while you are still in PC ASSISTANT.
    Do a FRESH COMPASS CALIBRATION before first flight! All should be well.

    If for some reason your compass IS WAY WAY OFF ( like in the negative numbers )
    You'll need to do a compass RESET .
    How to reset compass below:

    Take care, Fly safe!
