Step by step

How to fix it

Work through these in order, the most common causes come first.

  1. Power-cycle it properly

    Unplug (or remove batteries) for a full 60 seconds, not 5. This clears fault states that a quick toggle won't.

  2. Check the power path

    Try a different outlet, cable, and adapter. A surprising share of 'dead' devices are starved by a failing cable.

  3. Reset to factory defaults

    Look up the model's reset combination (usually holding a button 10+ seconds). Reconfigure from scratch afterward.

  4. Update firmware / app

    Check the companion app or manufacturer site for firmware updates that address known faults.

  5. Inspect for physical issues

    Look for debris, corrosion, loose parts, or swollen batteries before assuming electronics failure.

Frequently asked questions

Why does my webcam work in one app but not another?

The most common cause is exclusive access, another app is holding the camera. Close all other apps that may be using the camera. If the camera works in Windows Camera app but not Zoom, Zoom does not have camera permission or is not set to use the correct camera in Settings. If it works in Zoom but not in Chrome, Chrome's camera permission for specific websites needs to be enabled: in Chrome's address bar, click the lock icon, Site settings, and allow camera access for the site.

How do I test if my webcam is working?

Windows: open Windows Camera (search for Camera in Start). Mac: open FaceTime or Photo Booth. Both show the live camera feed without requiring a video call. If the webcam shows live video in these apps, the camera hardware is working and any issue with Zoom or Teams is a software configuration problem. If Windows Camera shows a black screen or error, the issue is hardware, driver, or permission.

My webcam video is upside down, how do I fix it?

An upside-down webcam image is a driver or app rotation setting issue. In Zoom: Settings, Video, there is no rotation option, so the fix must be at the driver level. Open the webcam's companion software (Logitech Options, Razer Synapse) and look for a rotation or flip setting. On Windows without companion software: Device Manager, camera Properties, Advanced, some drivers have rotation options here. As a workaround in OBS or Zoom: use the virtual camera feature in OBS with a rotation transform applied.

Why is my 4K webcam only showing 1080p?

4K webcam resolution must be selected in the application settings, not just plugged in. In Zoom: Settings, Video, camera settings, and change resolution if the option is available (Zoom limits to 1080p in calls). In OBS: Video Capture Device source, Properties, Resolution, set to 3840x2160. Some 4K webcams require a USB 3.0 port for 4K output, on USB 2.0 ports, they automatically downgrade to 1080p. Verify the USB port being used is USB 3.0 (blue port on most PCs).
