I have seen this problem occur on a client's Dell laptop before (cannot
remember the exact model).
Same problem description, for a few days prior to the fault occurring,
they noticed the screen "flashing", then finally one morning they
couldn't see anything on the screen.
An external monitor worked fine, but the display was blank - upon closer
inspection, you could *just* make out the display image.
I was able to open the screen surround, and observed that somehow the
two wires that power the LCD backlight had become caught in the opening
mechanism and had been cut, causing the fault.
A repair was ruled out due to the price of laptops being quite low
comparatively, and as it functioned perfectly with an external monitor,
it became a desktop-based laptop.
Hope that helps some.
