Webcam black/blank causes
- Verify the correct camera is selected in the app with steps above
- If you don't have a webcam with a cord you'll need to use the webcam built into laptop above the screen which means laptop lid can't be closed
- Verify the webcam privacy shutter is not red. At top-middle of laptop screen is a little grove that controls sliding a cover over the webcam, red means its blocking the webcam:
- We've seen where a stick-on (white/Nexus) privacy cover was added causing there to be two seperate covers, please remove the second cover
Top of screen: 
- From top/above: 
Webcam advanced controls: auto-focus, auto-brightness, & more. Not all cameras allow these changes

Camera app, Settings gear top-left, expand Camera, enable 'show advanced controls...', back arrow top-left, focus button move slider up from Auto to whatever focus works best

Properties window(s) pop-up allow you to make changes, after you hit OK you are shown webcam with your settings. If you need to adjust settings again simply re-follow the steps
