Camera freezes when screen is <90º open

The camera works when the screen is open more than a 90º angle and if I adjust the screen angle it’s fine until it’s less than 90º, then it freezes and I either have to restart it or run sudo killall VDCAssistant.

I’m on Sierra but I don’t think it would matter. I also did the permanent GPU bypass with the resistor so the defective dedicated GPU is inactive.

Could it be a pinched cable, and if so, why has it only started doing it now?

I’ve taken it apart and done some stuff but none of them involving taking the screen off. I did take out the optical drive because I had no use for it and the camera cable runs along it, but I don’t see why that would affect it.

Reseating the cable (pulling away, not up) had no effect.
