Under normal circumstances, a computer monitor will not remain powered up if it is not receiving a signal from the cpu. Whether or not this is the problem in your case is difficult to say. First steps would be to check all the cable connections to the monitor and cpu, and if that doesn't solve the problem, try another monitor with your cpu to see if it truly is your monitor that is bad or if what you describe is just a symptom of a larger problem. Good luck!

I switch on my PC, ensuring that all cables, leads
and power supplies are connected properly. The tower powers up no
problems at all. I switch the screen on, the green led lights up, the
screen is completely black. A blue box appears centrally on the screen
with the text 'power saving mode'. The green led light turns amber and
then the screen just goes black.
Please don't suggest going to control panel, as I can't get that far.
Hi, if the monitor stays on "saving mode" it means you have some bad capacitors inside the monitor, so you have to get it fixed. If you connect another monitor and you still get the same thing, it means the display's resolution is out of range. So restart safe mode and reconfigure it. I hope this helps.
"Press the "Input" button on your LCD monitor's front panel repeatedly at three- or four-second intervals until your monitor wakes up. If your monitor is set to an incorrect input mode, it won't receive a video signal. After you reset the monitor to the proper input mode, it will receive the signal and wake up automatically."
Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:
* Off entirely. * Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode. * Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer * On fully, receiving an image, and displaying.
