Hey guys, really scratching my head at the moment hopefully someone here knows what's goon on. I'm trying to get my fpv to work, I have immersion rc 600mw transmitter and a boscam diversity RX LCD5802 with a go pro hero 3 black, zenmuse gimbal and phantom upgrade board. When I turn the receiver on I get snow, turning the VTx on the snow turns to a black screen and the signal strength icon on the vRx goes to full bars. So looks like the system is working except I'm getting no video, just black. Is there any settings on the go pro that need to be set up for video output? Have tried the usb from go pro straight into vTx instead of going through the zenmuse connection and still no luck, also have tripled checked channel setup and they all seem to be correct. Really have tried everything I can think of, any help would be much appreciated.
