Only OSD, no video signal

Hi!

I’m having difficulties setting up the camera of a drone…

I have a Micoair743 FC, a small analog FPV camera and a Speedybee VTX.
Everything is connected together.
On an analog receiver I can see the OSD of flight controller. Battery voltage, current, heading, etc, but only a black video signal. I can not see the image of FPV camera.
When I disassemble the connectors and connect manually the FPV camera output to VTX video input, I can see the image - so the camera works.

Is there a setting in MissionPlanner, that I should enable to be able to see the FPV camera image and the OSD?

FC: Micoair743
Ardupilot: 4.6.2
VTX: Speedybee TX1600
FPV Camera: I can’t remember the type… :slight_smile:

My parameter file:

Thank you!

Just for the record: Problem solved by purchasing a different fpv camera.
The new camera is a CADDXFPV Ratel Pro. By connecting it to the appropriate connetor on the FC, it worked for the first time.
