Macbook Pro camera still not working (green light on) - tried heaps of suggested solutions to no avail
No, you have exhausted the typical steps and if you can send it in for repair or feel you won’t break it worse by opening it yourself, a repair is in order. 

Before a repair, make a backup of everything and wipe and reinstall the OS. You need that to start the repair and if it fixes things, you’ll save the cost and time of the repair.
