Been trying to install a back up camera in my truck for a while now.
First one would trigger the screen to switch to camera view when I put the truck in reverse, so clearly it's getting a signal from the camera. Camera power taps in the reverse light circuit. There's no other trigger to the head unit besides the video RCA cable. But, the screen would flicker showing scrambled video and say no signal.
In the interim I bought a front/rear dashcam. It had rear video when reversing so I was good. But then the tailgate fell off when I was forcing it shut against a bed full of scrap and hit the dashcam breaking it. Can't just get a replacement rear.
Figured the $20 camera that had been sitting in the garage for more than 5 years might be junk, I bought a new one.
Plugged the new one into existing cables. Screen doesn't flicker, but displays a blank screen with "no video signal".
Next I replaced the whole video cable thinking maybe the old one was junk. I did cut and splice the old one, so it's possible. Still no video signal. The lights on the camera light up and the head unit is getting a camera turn on signal but no video.
I'm stumped and frustrated.
