Could you give us more details, please? Does the PC starts and what happening after you press the power button? Can you hear the fan works? When the problem started and what was changed before the problem occoured? Have you checked the conection between PC and the monitor itself?

a flashlight on the dark screen to see if you barely see the icons on the
desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If the video shows on the external monitor that proves your video card is ok, ,but your lcd screen is bad. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.
