Please try the methods below:
1. Please make sure the voltage input is 5V or above. Try different power sources if possible.
2. Please connect the camera directly to a monitor/goggles (without any extension cable and TX/RX) as the picture below to see if it works
3.Switch PAL/NTSC system of the monitor.
4.Re-plug all the cables to make sure all are well connected.
5.Keep a distance of 1m and avoid wiring the camera near any other 220V/110V cable. If not, use foil wrapped coax cable to the camera which will help reduce Electromagnetic interference.
6.Reset the camera if you can access the OSD menu.
