How to Fix a Webcam Showing a Black Screen
Camera access appears allowed, but the preview stays black.
Before you begin
Start with reversible settings checks. Keep your device supported and powered safely. Do not force connectors, open sealed batteries or try high-voltage repair steps.
How to troubleshoot the problem
- 01
Inspect the privacy shutter
Open any physical shutter, check keyboard privacy keys and remove the lens cover.
- 02
Close other camera applications
Video-call software may control the camera. Quit those apps and reload the page.
- 03
Select the intended camera
On multi-camera devices, choose the built-in or external camera in your system’s camera settings.
- 04
Test different lighting
Move to a brighter area to distinguish low-light darkness from a camera failure.
- 05
Restart and check manufacturer guidance
Restart the browser and device. Only then consider a vendor driver update from an official source.
Check the result.
A successful live camera preview after these changes is useful confirmation. Persistent black output in every app may need servicing.

If the same problem occurs in multiple compatible applications or devices after safe checks, follow the manufacturer's exact support instructions or ask a qualified repair professional. A browser test cannot prove every hardware component is healthy.
