I am facing the problem with my hp wide vision hd camera (built-in camera). It is flickering on and off and i am not be able to use my camera. I have tried all solutions like from device manager solution, updating windows, reinstalling windows using the HP cloud recovery method. Still my camera is not working. I have daily meetings and camera has become very important for me. Please solve this issue and help me with that.

Check to see if there is a hardware problem: Watch this video.

Tap the ESC key after powering on. Tap it once a second after you see the LEDs on the keyboard flash. When you see the startup menu, press F2 to run diagnostics.

Run the webcam test.  If it fails during the UEFI test then Click here to check warranty

If the camera is not tested then possibly it is in the updated version of UEFI diagnostics.

HP releases newer UEFI diagnostics periodically.
When you select F2 during boot you are requesting UEFI diagnostics.
There is an updated diagnostics package Click Here
Look for the phrase 'issues outside the OS',
Expand the '+' symbol and click the DOWNLOAD button.
The version of the UEFI diagnostics is shown at the left of that DOWNLOAD button.
When you press F2 to run diagnostics please ensure the version is the new one.

This can be installed from a USB flash drive if necessary.

If no failure then windows drivers or file corruption could be the problem.

Let me know what you find out.

In the mean time, consider getting a USB camera.
