    I have a phantom 2 on firmware 3.04. I decided to paint my P2 and dis-assembled so that I could tape the insides preventing overspray. After re-assembly my P2 will no longer power on. As soon as I turn on the battery, all motors kick one time, all led blink once and I hear one quick chirp and the battery turns off.

    I have rechecked all connection and removed all accessories and still have the same result.

    I can not connect the assistant software to for diagnostics, so I have no idea what to try. I appreciate anything suggestions that you all might have.

    Can you post a couple DETAILED ( in focus ) pics of your
    Phantom interior components?
    1) MC ( main controller )
    2) all 4 ESC's ( speed controls )
    3) compass connection
    4) GPS connections,
    5) receiver connections
    ( and also check your COMMUNICATION PINS ON YOUR BATTERY )
    Does the battery turn on, and stay on , when not attatched to phantom?

    Please let us know, thanks!

    Take Care, Fly Safe!

    Hopefully the pictures in the link are detailed enough.

    I have checked the communication pins and they appear to be normal

    System Details that have been used successfully for 3+ weeks:

    P2 with H3-3D. Hole cut for the yaw motor and added a thin spacer.

    OEM motors replaced with T-Motor Antigravity.

    FPV HUB

    Immersion 600mw vTX

    Mini iOSD (located inside shell behind battery, above the USB port).

    CANBUS (inside the shell)

    In your #8 pic, it looks like motor plug to Naza is plugged in incorrectly. Double check your connections to NAZA

    I rechecked and believe that it is correct now. Unfortunately, I do believe that I had it connected incorrectly when I first powered on after re-assembly. Could that have caused a problem?

    Current connection along with a few other more detailed pics.

    Also, I have moved all of my accessories outside of the shell, so everything inside is OEM except for the zenmuse anti-interference board.

    I believe that I found the problem. I notice that motor # 1 had a slight kick during the power on sequence (none of the others did this), so I decided to remove that motor and then the ESC. Removing the motor did not help, but removing the ESC allows the P2 will completely power on now. I'm guessing the ESC must have shorted out somewhere in the dis-assembly/re-assembly.

    I guess the next step will be ordering a replacement ESC and hope that corrects the problem.
