If it’s out of focus than it’s easy fix; all you’ll need to do is to watch YouTube video.
but sometimes the camera itself is broken & if you attempt to turn on your Bebop that all it gives you is Blinking green light & nothing else.
to fix this problem all you’ll need to do is to watch another YouTube video while you remove the front Nose, remove the Camera housing, than disconnect it from the MotherBoard; Screw it back together & you’ll have a working Drone without the FVP(Camera view) but you can still fly it whiteout any problems.
All Thanks to parrot.com to have &&^&@@ us all; They manufacture Bebop Camera Replacement but for $300+ that they can go stick their heads up their ass, as I’m sure by now it’s the exact fit.
