Usually I can find a answer myself on google, but this time I need someone's help. On my p2 my osd mini is not showing up on the screen. I have a dji hub. So I know about the switch that turns it on and off. When off there is clear video feed. Turn it on, there is nothing. But I know there is transmission from the fpv tx because of the black screen rather then a scrambled one. I tried all configurations. Through the port on the pcb, through the hub, I tried a avl5.8 and a Flysky tx with a dedicated wire that connects the isod to the p2 and tx. Always the same problem. The can seems to be ok. I have a ground station connected to the isod can outlet. Tried it connected disconnect still the same issue. Any thoughts on what's going on. Or can someone direct me to some more info.
