Recently purchased 5100 NEX and installed a front view video camera.

 

Video feed was fine initially. At some point I stopped getting video

 

1. Went into AV settings, noticed the camera setting was off, so I turned it on.

2. Went into camera view, still no video.

3. Went back into AV settings, camera on/off setting is off again, turned it back on again.

4. Same thing keeps happening over and over. 

 

Camera view in AV settings keeps turning itself off. I turn it on, but every time I go back it's off again.

 

Any suggestions?
