The problem is that the lamp in your LCD panel has burnt out. This is a
fairly common problem.
The lamp provides the backlight that allows you to see the patterns that the
little liquid crystal cells are creating on the screen. Without it, the screen
appears black, but not quite. If you hold a flashlight up to the screen, or
if the PC is a laptop and you can take it to a brightly lit window and look at
the screen at an angle, you can see a faint hint of the standard patterns you
should be seeing.
The only cure is to change out the entire LCD panel assembly. The lamp is
sealed in the panel and cannot be changed by itself.
