Hey JosephSchramm - could you provide some more info/pictures(which device you have, which camera)?
I suppose you have FFC device. Cable for FFC device should be mounted like this:

Orientation is important; Blue part of FFC should be facing away from PCB on both ends.
Also I would suggest running depthai-core/utilities/cam_test.py instead of oak-viewer here is how.
Thanks,
Oskar
