LCD cable bad or Webcam bad?

I have a P-7811FX laptop with windows 7x64 Ult sp1 installed and when I installed all the drivers from the gateway site they all worked except one. The webcam driver would load but it would say webcam driver failed to load and to restart computer to load the driver. I did that but it would still come up with webcam driver fail to load. So how would I go about testing whether the cable was bad or the webcam was bad? My LCD shows now white lines or banding as the cable is all one unit together. I did uninstall and reinstall the webcam driver and got the same results again. Both are not expensive to buy as they are used but I like to narrow done which might be the cause as that would involve talking about the LCD display panel to get to the cable backing.

 

My opinion would be LCD cable first because there isn't a way to test whether your webcam module is good or not without a good LCD cable (as you said, the cable is all one unit together). Once you have the LCD cable, then you'll know whether your webcam is working or not.

That being said, the symptoms you describes, white lines or banding on LCD, those are more of the cable issue than webcam issue. If the webcam is bad, then either your laptop won't detect it or it'll detects and work abnormally.

When i had LCD cable issue with my old HP dv6000 laptop, I rocked the LCD lid back and forth because the LCD cable on that unit goes over the left hinge so rocking the lid moved the lcd cable and if the cable was bad, changes in the screen like more white lines, less white lines, color changes appears.

Hope this helps.

 

That the problem I am having it will install but fail to load the driver but does detect as USB webcam and it says to restart program or restart computer. It does detect but fails to load the driver. To me this sympton is indicating a bad webcam and I did try rocking the screen and the display did nothing indicating bad LCD cable.

 

Reporting back got my webcam back....wheww...what I did was installed the driver/software from my P-6860FX for x64 and it worked....not sure why the version for the P-7811FX didn't work? But I can say for sure now the webcam software for my P-6860FX works on my P-7811FX webcam. Why I am not sure but it works...rebooted and tested and it works....
