Answers :

If the screen is always blank, even on startup , before loading Windows, than this is probably an hardware fault.

Try unplugging the laptop and removing the battery at the same time, wait 5 minutes, then put the laptop together. This will drain power and reset the laptop.

If that does not work, and you get no pictuer under any circumstance , then there is a fault.

If the screen is black with no light , then it is either a faulty inverter or a problem on mainboard.

If the screen is all lit, but is blank with no signal, then it is often because of a bad LCD ribbon cable , but can be again the video chipset on the motherboard.

Try connecting to an external monitor, if it works then problem is restricted to LCD/inverter and ribbon cable, if it does not work on external monitor is usually a bad video chipset on motherboard.
