    Ok so I did have a very bad crash the other day. The bird flew at full speed at a large metal object......think the compass was affected. So instead of crashing full speed into this object (water tower) I decided to kill the motors and let her come down from about 10 feet. well it flipped over and landed on the top ejecting the camera. I found all the pieces and ordered a replacement cable. Now I installed the cable, which came with a small bend in it from shipping, and did an IMU calibration. However the camera now powers up and moves to the right and then stays there. There is resistance from side to side but up and down there is none. The red light on the camera blinks red too.

    Anyone have any idea what is going on? I tried making sure all the cable connections were good and did several IMU calibrations. Is it possible that the flex cable I have is bad? Please help I have several jobs that require my bird. Thanks

    Hello,
    If you crashed top first ( inverted ) then unfortunately you might have damaged the gimbal main board, these are prone to this sort of damage, on inverted crashes, you see the gimbal slams the belly of phantom, causing one of 2 issues.
    1) some circuits are soldered from underneath, in a solder bath style circuit board assembly, these crashes can cause the connection to break, and are unseen to the eye.
    2) there is a small circuit on the top of the gimbal boards, for some reason this circuit gets smashed in those style crashes
    Here is a picture of what I'm talking about, with the circuit circled.

    Please scrutinize the board ( CLOSELY ), for damage.
    If you need a replacement, let me know! I know a guy.

    Hope this helps.

    J Dot,
    So I took the bird apart today and this is what I find. Looks ok to me but what do you think?

    Ok so I go out and pick up a new ribbon and put it in. I get camera view and can start and stop video and take pictures but the gimbal is dead. I have a constant 3 beeps with a green light on the gimbal. Message on the screen says remove gimbal guard but there isn't one on. Anyone have any idea's how to fix this?

    Hello,
    Have you tried to hold camera level at startup, I'm thinking a roll/pitch board, or motor bad?
    By holding the camera at a different position during startup, might hit a different spot on the potentiometer, and may work, may not? But might offer more insight to what is wrong?



    Check your roll, and pitch boards, the potentiometers might be messed up, or the motor/s, could be obstructed, or bent.

    Try spinning the motors by hand to see if they move freely, or are hard to move?

    Let me know your findings?

    I have trie starting with camera in a diferent position and the gimbal is just limp. All gimbal motors move freely so I think that the board might be fried. JDot thanks for the ideas and help.

    No,
    I sure don't. I usually just swap them out.
    I have 4 bad ones myself. 1 kinda good one, works, but camera roll is off by several degrees. Won't level out. But works just fine, if you need a V8! :)

    J Dot,
    I have found what my problem is. The 3 gray cables that connect to the gimbal board are damaged. Are you aware of where I can get replacement cables? I checked ebay and none were listed. Mine the wires pulled out from the connectors. Thanks
