Screen started showing a vertical stripe

I have an Acer Aspire 3000 laptop. A couple days ago the screen started showing a vertical stripe about one inch thick and about one inch in from the right edge of the screen. The colors in this stripe appear ‘washed out’- they’re still there, but paler. I’ve updated the video driver (a SiS driver), but it didn’t help. Any ideas?

Most likely that is the LCD screen fault. Just in case connect an external monitor and restart the laptop. If you see the same strip on the external video, then that is the motherboard or the video card (if it’s a separate module) problem.
