Webcam not turning on after screen replacement?

So I've recently replaced the screen on my M1 MacBook Pro and the webcam doesn't seem like it wants to open up? Ran the Apple diagnostics tool and it doesn't seem to report anything wrong with the camera. Checked System Information and it does seem to show the model ID and Unique ID. The green light indicator slowly flashes as if it's trying to turn on.

Does it require reinstalling macOS? Or does anyone happen to know which cable is responsible for the webcam so that I can try reseating it. Thanks!

I've just had the same problem.The problem persists with two different, new screen assemblies. Both are brand new, correct screens (for A2338) and camera works with neither. When I fit the original broken screen assembly - the camera works. Either I'm VERY unlucky or this is some Apple magic that's disabling cameras on non Apple Original screen assemblies ??

I never got it to work. I got some amount refunded from the seller. I never found out if the camera is broken or if it really is a software issue, but I would assume that the OS would complain with some warning if it's not a "genuine" part, like they do on the iphone. Please post here if you find a solution.

It sounds like there is an issue with the display you installed. Are you sure you installed the correct display? If an incorrect model display was installed, it may appear to be functional but will have issues with component functionality such as the camera, backlight, or TrueTone. I've accidentally installed the wrong model display before and everything was functional except for the camera. Alternatively, it's possible the display was damaged during installation. Was the battery fully disconnected when you installed the part? Did you have any difficulty during the installation? Do you have another working screen you can test with? Good luck!

I have the exact same problem. I did install the correct model of screen and did not break anything. The camera is also detected correctly by the mac. Sounds like this is a Apple non-genuine check thing. Any way to clear it?
