Description: Simple but common troubleshooting tips/guides.
How-to Steps:
Unplug/Replug (If applicable), to restart the connection between the camera and device.
Turn off/on both device and webcam.
Check your antivirus settings. Antivirus software can occasionally interfere with webcams. Investigate the software settings to see if your antivirus is preventing your camera from launching.
Plug the webcam into a different computer. If using an external camera, plug it into another device to make sure it works. If you're having problems with it on multiple computers, it's time to get a new webcam.
Check the device connection. If using an external camera, make sure it's properly connected to your computer. Jiggling the cable or simply unplugging and plugging it back in can work miracles.
Check the USB port. Of course, connection problems can occur on your computer's end as well, so try plugging something else into the USB port to rule out that issue.
Make sure the correct device is enabled. If you have a built-in camera and an external webcam plugged in, then applications can get confused about which one to use. Check the application's settings and find the option to select your preferred device.
Consult the manufacturer. For external webcams, check the user manual or the manufacturer's website for further guidance.
