hi all i have recently purchased a matek vtx and when i try to hook it up i get nothing, i will attach pics for people who have advice can check what i have done wrong but i feel i have followed the images on the matek web site..
the white wire you see is the one they say should be blue for smart control that does not work either , i then connected my older bulky boscam vtx wired the same way and all works fine proving camera etc works fine many thanks any questions please just ask

Can't tell exactly by your pics, but it appears you're running the video signal from the camera to the flight controller and then to the vtx, correct? What flight controller are you using?
 
assuming the yellow wire is video in to the vtx, White wire needs to be in the audio spot (smart audio)
Not sure about the transmit and receive spots
 
Oops, Go from camera to rx on flight controller, then tx from fc to tx on vtx. audio goes to audio
(according to the above video)
 
The board is a matek f4 osd . I'm gonna have so strip the whole thing down this evening and run direct from cam to vtx to test it all
