Hey,
     I have a phantom 2 with hero 4, zenmuse H3-3D, and fat shark FPv goggle setup. The system has been working quite well until the last few days, and the FPV only shows a gray screen. I thought it might be the wire going from the Phantom 2 board to the immersionRC transmitter, and replaced it, however this was not the case. I have attached the small camera that came with the fat shark into the Immersion RC transmitter and it worked fine, I have also checked the firmware updates etc. I am a bit stumped at what might be causing this issue. I don't think it is the transmitter or a goggle issue, or the smaller camera would not have worked fine.
   Any suggestions?
         Thanks

Any suggestion on this ?
