    I say 'unexplainable' in the hope that someone will actually explain a possible cause for this issue I have been fighting for months... Searching various forums, never finding a fault quite like what I am experiencing (I could be looking in the wrong places).

    I have an inspire with dual remotes, one with iPhone 5s, one with iPad Mini 2 - very regularly (on average 50% of the time) I will experience low signal transmission of the image. This can be represented in various ways, digital noise, green bars, black screen, about 2 second lag on the feed or all of these issues at the same time.

    This doesn't only appear on Live view whilst flying, but also if reviewing photos on the SD Card through the 'DJI Go App' (whilst the issue is occurring a photo preview will keep trying to refresh, never fully loading the image, a video will not load).

    My troubleshooting so far:
    - Command & Control signal to the Inspire is never effected
    - Video stored onto the card is never affected (thankfully)
    - A different camera yeilds the same results
    - Sometimes one controller has a perfect signal whilst the other does not (slave can have perfect signal whilst master does not)
    - Sometimes both controllers are affected at the same time
    - The issue can occur with just one controller attached although maybe less frequently
    - The issue can often resolve itself or start mid flight
    - The issue can occur 50cm away from inspire or 500m away
    - Different lightning cables appear to make no difference
    - Closing all background apps has no effect
    - Issue has remained present through multiple app updates and firmware updates
    - Issue regularity appears to be increasing

    Since you have ruled out firmware (it has happened throughout different versions), camera, controller and presumably SD card (yes a faulty card can cause strange issues with the live feed).
    I would say your problem points to a hardware issue with the Lightbridge.
    Before going down that route some things to try.
    • Make sure all four antenna plugs are firmly seated in their sockets (easily accessible and viewable just behind nose cone)
    • Although you have tried another camera make absolutely sure (and I mean magnifying glass sure) that the gimbal connection plate pins are not out of alignment/bent
    • Ensure the two gimbal connection ribbon cables are firmly seated in their sockets on BOTH ends (you will need to remove the nose cone for this one
    Give the above items a check and try again.

    I will try these steps and see, but surely if at times I can get perfect signal on one controller and poor signal on the other it cannot be caused by an issue on the airframe?

    My set up is similar (2 iPad Mini 2) and I have similar persistent image transmission issues and now am getting occasional corrupt video since GO APP 3.0.
    If I find relief I will share here.
