1. Check cables in the back of the monitor, and on the back of the PC.
2. It could be a faulty cord, or power supply.
3. Check the Device Manager for any problem occuring, around the same time the monitor went blank.
If there's a problem, you'll see either a red X, or a yellow exclamation mark, next to Monitors, or Display Adapters.
If it show a problem, right click the device, select Properties, and under the General tab, see if it tells you what the problem is.
4. Try updating the drivers for the Monitor, and Display Adapter.
There's a Tutorial here, explaining the process:

What kind of monitor is it? What kind of PC (laptop/desktop, make and model) is it?

I just laid my laptop down on the bed (upside down) and came back to a very dark screen - a couple of keypresses later I discovered the keyboard shortcut that had done it.

Some LCD monitors have trouble with the "inverter" - which I gather is a part that can fail in this manner. Try another monitor to see if that's the case here.
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

Thank you very much!
it's a notebook--acer TravelMate 2350.
the keyboard is OK.
i use another monitor ,but it doesn't work .
My uncle tells me maybe the cables which connect the monitor and the mainboard become flexible.
with that answer,i did something.now it's OK.
