Tecra M11-17V with Windows 7 - Web Cam image is very grainy

Hi,

Yesterday my webcam (built into the laptop) worked perfectly, today it doesn't....

Whenever I use it now, the image is very grainy, almost like a tartan pattern of criss-crossing lines, but I can still just about make out myself in the background. Movement and sound are still being recorded, just the image is strange.

Please help! Has anyone else had this happen? Is this something I can fix myself, or is it a hardware problem? I have had this laptop about 3months, from brand new, and this is the first problem I've had...

Many thanks,
Dom

Hi

Usually the webcam lens is covered by a thin foil which needs to be removed for the first time. But I think you did it in the past because webcam worked properly in the past. Right?

Well, I think you could try to reinstall the webcam software.
Not sure if this helps but it worth a try… so try it.

Hi Paolo,

Thanks for the tips, but I'm afraid my camera is still out of action....

I've double checked that the protective lens film has been removed, and I've disabled/re-enabled the camera device, updated the camera driver, and completely reinstalled all the camera software to no effect. I've also ruled out conflicting software issues, as the problem persists for both skype calls and the laptop's face recognition software used when logging into my account.

The frustrating thing is that the fault happened suddenly halfway through a skype call. It was working perfectly on minute, and broken the next (seemingly irreversible.... fingers crossed). I had used skype for a mammoth 3hr call the night before, but I hope that wouldn't have "burnt out" the brand new camera...

Do you, or anyone else, know if sounds like a physical problem? Are web cam hardware faults common? I have never dropped the laptop, though it does commute with me on the train into work everyday...

When I first got the laptop, the inbuilt fingerprint scanner didn't work very accurately until I updated the driver software. Is it common for faults to suddenly appear when drivers become "out of date"? Any chance these problems could be related?

Thanks again for your help,
Dom

Are you using the webcam in clean and brightly environment /rooms?
Test the cam in broad daylight.

As last workaround I would recommend setting the notebook back to factory settings using a HDD recover or Recovery disk. Then you could test the internal webcam without an installation of any other 3rd party software.
