Interactive Decision Tree
Camera Troubleshooter Wizard
Answer one question at a time about what you are actually seeing, and each answer narrows down the next question — ending on a specific, matched diagnosis rather than a generic list of things to try. Prefer letting the browser check automatically instead? An automated-check shortcut is available at every step.

What Each Path Leads To
| What you're seeing | Likely diagnosis |
|---|---|
| Black screen, LED light on | Physical cover or app-side rendering issue |
| Black screen, LED light off | Sensor not activating — driver or OS block |
| Error mentioning "permission" or "denied" | Browser or OS-level permission block |
| Quality issue — lighting | Not a hardware fault — lighting problem |
| Quality issue — focus | Autofocus or minimum-distance limitation |
| Not found, external USB webcam | Physical connection or USB port issue |
| Not found, built-in laptop camera | Likely disabled at OS or BIOS level |
This is a static summary of the wizard's real branches — the interactive tree above walks you through reaching the right one for your specific situation.

Common Questions
Frequently Asked Questions
How is this different from the Camera Block Detector?
The Camera Block Detector runs an automated sequence of technical checks for you. This is a guided decision tree you click through yourself, answering plain questions about what you are actually seeing — useful when you want to understand the reasoning, or the automated check alone did not resolve things.
Can I skip straight to the automated check?
Yes — an automated check button is available at any point in the tree for anyone who would rather skip the questions entirely.
What if none of the answers match my exact situation?
Pick the closest match — the goal is narrowing down the general category of problem, not an exact description. If the result doesn't feel right, click "Start Over" and try a different path, or use the automated check for a technical reading instead.
Do I need a camera connected to use this?
Not for the guided questions — those work from your own observations. The automated check shortcut does need camera access to read the real technical error, if you choose to use it.
Does this work for microphone problems too?
No — this wizard is specifically built around camera symptoms. For microphone issues, the Microphone Test and its troubleshooting notes cover audio-specific problems.
