I have a furibee x215 pro racer drone and I have been learning how to fly it (my first drone), I did not crash anywhere real hard but I finally got my FPV googles eachine EV100 to start with but I am getting no video, just black screen.
I have been trying to figure out what might be wrong but no luck since then.
I do autosearch on googles, it picks up signal but not at the frequency that my vtx is streaming (I compared vtx frequencies table with google frequencies table from documentation). Sometimes it does find the correct frequency, but mostly not. And I get only black screen with frequency on googles. When I switch to other channels on googles, sometimes some of them are black too and most is just noise.
Also, when I do autosearch, it finds a signal (correct signal from vtx), Im getting black screen, I turn off googles, turn them back on and they show noise on the same frequency (before I powered off). So there is some magic in it
There was a connector on the pcb which fell off so I soldered it back (before I tried googles) , but I thought that I might solder it bad and it was hard to take it off, so I soldered camera wires directly to pcb pins.
Now real deal is, on the website where I bought drone https://www.gearbest.com/brushless-fpv-racer/pp_708379.html description says, that camera needs 12V DC input voltage. Whats weird is that the power that goes to camera is only 5V and that was original when I bought it. So I am not sure if they made a mistake (which I doubt since nobody had ever problem with it) or it can work on 5V. When I power on the drone, after a minute or two I can feel that camera is getting warm a bit so it should be working.
Now, what can I do to figure out, whether my googles are bad or some part on the drone? I have no other camera to try out or googles or vtx. Just one drone and one googles.
Thank you all for help.
