Skydroid T10 and 3 in 1 camera issue

Hello. I bought Skydroid T 10 RC with R 10 receiver and 3 in 1 camera. When I try to connect the 3 in 1 camera to R 10 receiver, all the pin are correctly inserted but I can’t access video output from my screen that linked with the T 10 transmitter. How could I do plz?
