I need help. List of things I've done already in no particular order: - Replaced flexible ribbon cable for gimbal [Part 49]. - Replaced every cable provided by Part 42. - Inspected every connection/component for any damages/disconnections. - Upgraded/downgraded to every firmware (currently 1.3.20), failing each time (two devices are "not found"). - It makes that really long beeeeeeeeeeeeeeeeeeeep after a few cycles of dd-d-d or d-d-d-d. - Re-binded controller/craft each time. - Upgraded controller to latest firmware. - Using this really fast microSD card. - Played with auto/manual frequencies and enabled/disable hardware decode. - Set phone on "Airplane Mode", closed all the apps, plenty of space, reset springboard. - Reconnected the iOS cable to see if it comes on. - Tested in a "large open space". Things observed: - It flies. - "No Signal" in red across the top. - No live feed (main problem). - Histogram shows changes consistent with lighting. - Can take photo/video, saves to card, and download to phone but it cannot be viewed from DJI GO app itself. This can be done at any distance so far. - Gimbal calibrates/moves successfully. - IMU calibrates successfully. - Compass calibrates successfully. Hardware Info: - Phantom 3 Professional (Craft and remote was sold separately) sold as-is from a private auction site, it appeared that it suffered from a mild crash, only notable damage was the gimbal arm slightly bent. I'm not sure if there already was a video signal before I started the gimbal repair since the remote control came in after I did the repairs. - iPhone 6+ (running iOS 9 Beta 4), I have nothing else that supports the app. - This Cambond cable. What should I do next? Thinking about just selling it as-is if I don't have a solution by the end of the month. Would replacing this solve my problem? If not, what should I do next?
