Hi goki23,
Thanks for coming to Apple Support Communities for help today.
It appears you have seen the correct article for your MacBook camera. Did you try every suggested step?
You can also test the camera inside a new user account. This will let you know if the issue is system-wide or isolated to your user. If it is system-wide, this typically indicates a hardware issue. Here's how to Set up users, guests, and groups.
If the issue continues inside the new user account, Contact Apple Support.
Have a fantastic day!
