The whole point of a webcam is to be able to see the person you are speaking with, and let them see you. When the image broadcasted by your camera is too dark, the person on the viewing end won't see anything but shadows and dark shapes. Learn how to brighten your webcam image so the people you chat with can see you.

Place lamps behind and to the side of the webcam. This casts a light on your face, but the lamps will not wash out the image because they are behind the camera. Turn off lamps that are behind you. You have trouble seeing things when you are looking in the direction of the sun or a light bulb. Your webcam has the same problems. Don't make it stare at a bright light. Open up a white screen on your computer to brighten your face. The white screen will create the brightest possible light from you computer screen and help lighten your webcam image. This option is best when lamps are not available. Open up an empty tab in your Internet browser, or a blank Notepad document, and expand it to the full of your screen. Adjust your webcam settings. The settings available to you will depend on your webcam, but many of them offer a "Brightness" setting that you can increase to lighten your webcam. Open the program that came with your webcam, then look for a "Settings" or "Options" menu. Increase the "Brightness" setting until it has lightened your webcam enough.

Sounds like either your inverter might be failing or your graphics card. If the screen goes really dark, but you can make out images in a bright light, it's the inverter. Fairly easy to change if you look on the internet you should find full instructions for your make and model, often in you tube. Good luck.

Have you tested it with an external monitor?

I would say you either have a damaged inverter board or screen baclight lamp. Usually the inverter board fails in one of the following ways:

1. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable. When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor.
2. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop works fine with an external monitor.
3. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above. When you restart the laptop, the screen works fine again.

Inverter failure symptoms are very similar to backlight lamp failure symptoms and in most cases you cannot tell which one is causing the problem until you replace either the inverter board or the backlight lamp. From my personal experience, inverter boards fail more often than backlight lamps. If you have to guess, replace the inverter first.

• Exposure adjusts the overall intensity of light in an image.
• Adaptive Lighting improves only the dark areas in an image without affecting the bright areas.
• Brightness adjusts the amount of light in colors ranging from light to dark.
