My beta85 HD is not receiving video in my fpv goggle!

Hi everyone,
I am still a beginner in the hobby. I crashed my drone and I broke the frame of my beta85 drone. I was still able to receive video from the drone to my goggles. After I took apart the drone and reassembled it I discovered that something is wrong with the video being transmitted to my goggle. I keep scanning for the channel and nothing is showing up. I checked the wires and connection and nothing seemed damaged. Any idea would be helpful. thanks all
