My LCD's backlight seems to be going out or thats all I can make of it. At first I thought it was just completely going off, but then I noticed I could make out a faint image. For example, if I was surfing the net when it went off, I could scroll up and down and just barely make out the page moving. This tells me that the video card is producing the image, there's just something going awry on the LCD's end? How can I fix it? Is it worth it? Any help is appreciated, thanks.
