Cameras guides
Webcams, action cameras and memory cards — cameras not detected, power failures and cards a device won’t read.
7 guides
Webcam not working
Fix a webcam that won’t show a picture: the Windows Camera app bypasses every other app and splits the fault in two. Covers the privacy shutter, the three separate permission switches, apps holding the camera, and Device Manager.
GoPro won’t turn on
Fix a GoPro that won’t power on: GoPro’s own sequence starts by removing the SD card, because a corrupted card can hang the camera during boot. Then running it with no battery on external power separates a dead battery from a dead camera.
SD card not detected
Fix a memory card a camera won’t read: a computer and a card reader separate a physical failure from a formatting or compatibility one. Covers the lock switch that slides on its own, where to format, and cards that are merely too slow.
GoPro not connecting to phone
Fix a GoPro that won’t pair with the Quik app: stale data sits in three places, not one. Covers the phone’s Bluetooth and Wi-Fi lists, the app’s own camera history, the 2.4GHz band setting and iOS Local Network permission.
Webcam microphone not working
Fix a webcam microphone nobody can hear: Windows records a sample and plays it back, which splits the fault in two. Covers why camera permission does not cover the microphone, input device selection, levels and exclusive mode.
Canon EOS R6 Mark II Wi-Fi failure
Canon's manual distinguishes a missing connection target from DHCP, DNS, duplicate-address and wireless-network errors. Open Error details before changing settings; each code points to a different part of the connection.
Webcam blurry
Fix a blurry webcam: only autofocus cameras can be corrected in software, and light is the usual culprit. Covers the local-preview test that separates a soft camera from a video call reducing quality.
