Inspiron 3521 webcam problem

Hello everyone. I have a problem with my laptop's integrated webcam.

A few days ago it suddenly stopped working. The white led light next to the lens turns on but the image window on the screen stays black. I have not changed anything regarding the software, I tested the functionality with online webcam testing pages and also the image keeps loading in Skype.

I have checked the support for webcam and graphics drivers which I'm pretty sure I have updated to the latest version.

Also I have tried to uninstall the device from the device manager list and have it automatically reinstalled with no luck.

Is there anything else I can do?

Thanks in advance for your answers!
