If anyone has one of these, it's worth pulling it apart BEFORE it fails...
Mine stopped working wirelessly - but any number of problems were hiding under the plastic covers. Wired operation was still ok.
Four philips screws on the rear - and you can pop the clamshell apart -
You don''t need t undo the WiFi antenna connector - it can stay where it is.
The problem I needed to fix was a 1000uF 6V3 electrolytic which was bulging slightly. (replaced with 10V - circled in photo)
To get him out - you need to disconnect the camera gymbal and motor assembly - which revealed problem #2 - broken shock mounts. The camera had never to my knowledge been dropped etc - but three of the four rubber mountings were totalled.
Depending on your circumstances - you can reconstruct the plastic lugs as needed around the rubber grommets and screws, (Photo shows how I 'ballsed it up' neatly).
Massaging the main PCBs out of the case is straightforward - but you need to wriggle sideways a bit around the antenna connector.
The WiFi module is socketed (DIMM - under camera assembly) onto the main board and is easy to release. I just unplugged and reconnected it to 'clean' the edge connectors.
Jumpered everything back together - and all working as it should... except the main clamshell assembly screws were also toasted (one of four was holding, but plastic split).
A bit of 2-part epoxy and some heatshrink sleeve (photo) around the 'plastic posts' will hold them together for a few more years.
Good luck!
