I bought the Frontech Diamond webcam and installed the CD and the message shows its successfully installed, as its requested i restarted my system. After i open my cam,, the light will ON but in the CAM...

check if your USB cable is properly plugged.
Also try connecting your webcam directly to your PC instead of through a USB hub

if your webcam's image is not sharp, check to see if it has a focus ring. A blurry image can sometimes simply mean the webcam is not in focus. Adjusting the focus through the ring can solve that problem.

Other picture quality problems with webcams can be addressed by changing the video capture properties for the webcam. Most programs that can use a webcam will have an option to access the properties of the video source, which will bring up the video capture properties window.

NISSAN MURANO 2004 I receive an error on my screen Check Engine & after checking at the garage the problem was P0340 what would it be ?? & how to fix ?? when running on the highway the engine...

the P0340 is a camshaft sensor code, the sensor is located in the front (passengers ) side of the engine, there should be two sensor's one for each camshaft, (front of each head) defective cam sensor's can cause the the problems of stalling and hard starting. I am a Nissan certified tech and replaced a good number of cam sensors in the past, they are quit easy to replace, they are attached by one ten millimeter headed bolt (per sensor) remove the bolt then work the sensor clockwise and counter clockwise while pulling out, there is a o ring seal on the sensor and when installing the new one lightly lube o ring before installing, then install sensor and be sure it fully seated against the mounting surface before installing the bolt or you will break the mounting ear of your new sensor. thanks for using fixya

When i click on it, it says web cam is not found or not working properly

check the device manager if imaging device is detected
XP: click start > right click my computer> properties > hardware tab > device manager check if theres any imaging device listed if it has an exclamation point uninstall and reinstall the drivers
if you have other devices listed get your drivers disk and install the drivers.
if theres no bang or let say everything was installed properly camera is busted and needs to be replaced
hope this help

The images produces on my web cam are blurr and can't be viewed. if you pass an object infront of it you just see a shadow.

most webcams have a focus ring on the front of them, try adjusting that ring, turn clockwise and counterclockwise to adjust focal point, the other thing may be the brightness setting in the control panel for the camera, open control panel , look for "cameras" locate your webcam icon , then look under properties. There should be settings for contrast.. brightness. color ect.

Web cam do not turn on for pavilion dv6910

There are two files needed for the webcam to work. Go to the HP support driver page and look for the driver for the Cyberlink Youcam. You'll have to put the exact model number in a special search box in order to download the youcam software from HP
