Re: monitor turns off automatically..
It's possible that the ACPI (Advanced Configuration and Power Management Interface) is not enabled in the bios.
To access the bios either press F2 or DEL, depending on the motherboard(usually tells you on the initial boot screen), then look for a line that reads 'Power Management Setup' or similair and press ENTER.
When into the menu check to see if ACPI is reading enabled,
if not press the right arrow on your keyboard then either press PAGE UP or PAGE DOWN or + or - on the keyboard.
Press 'ESC' then it will ask if you if you want to save changes, press'Y'.
That should sort it.
I have an HP vs17 monitor with the same problem. I called HP and they said that there is no warranty on their monitors and that this is a common problem. They went on to say that it is the same cost to replace this monitor as it is to repair it.
I tried turning down the resolution, auto adjusting the monitor, setting it to the native resolution of 1280x1024 @ 60Hz, replacing all cables, tweaking the video settings, moved it to another computer and none of it helped. I even took the dam thing apart and checked the Ohms reading on the fuse inside, it was good. Nothing looked or smelled burned/broken. This thing is just malfunctioning...something to do with the power save feature I think.
I have this problem with my HP L1940 TFT monitor, i have been using the computer through this monitor it gives only one second display, and then it give one message in screen, after this message it will be turns off automatically.but green led light is on stage,so give correct solution.

there are many reason why a monitor suddenly turned off then back to work again , over use may over heat that cause the soled parts on the printed board of your CRT go loosen , try to re sold it, sometimes your PC might stop viewing so the monitor automatically shot off stby mode , loose connection due to basted parts , capacitors,power regulators,resistors , even the cables also might be.
For the monitor that is more than 2 years old, first place to look will be the power supply, look for bad caps with bulging top first, post back what you see inside so we can guide you further, see example of failed monitors due to bad caps; http://s807.photobucket.com/home/budm/allalbums
Make sure that the power settings are set to never turn monitor off. On Win Xp, you go to control panel, power options, then check your settings to see if it is set to turn off after an hour or so, if it is then click on the down arrow and choose "NEVER".
The presentation power scheme is used when you are giving a briefing using the PC as your slide show. So the presentation power scheme will never shut off the monitor or the hard drive, don't want it to shut down in the middle of a briefing.However, leaving it in that state for long periods of time may cause the CPU to overheat and shut itself down for protection. A better scheme for quick boot up would be Home/Office. Turn monitor off after 20 minutes and "never" for hard disk. This way it will save energy (therefore heat) and you will have a quick boot up. If you are using XP Pro, there is also an option to automatically put it in standby when you close the lid of your monitor. Hope this helps. If you have any questions let me know...

Try replacin a new display card. If it is fine working.ok
If not try fixing for cold solder in the video section.
I suggest video section according your report the light green LED lighted that shows the power section is doing fine.
mcdevito75 here LCD, or liquid Crystal display, chances are the crackling is the inside liquid display trying to capture the in comming electricity to make a display picture. Remember even an LCD is nothing more than a light bulb, a very intricate light bulb but a light bulb, and you have light bulbs burn out when you put them on and almost never as the are on burning. Turning the monitor itself off won"t really save electricity or the monitor itself as, when you shut down the computer from Start (left side of screen) the monitors screen saver comes on for 10--20 minutes then goes off, at this point the electricity is at the monitors on/off switch and not going thru the monitor at all. If you turn the monitor off at it"s on/off switch, the sudden jump of electricity to the monitor from it"s on/off switch could hurt it, or even the switch. I have a friend who turns off the monitor also and that friend had a bad monitor in 3 years. I never turn my monitor off just the computer itself. I'd speak with a Radio Shack, Staples, Best Buy ETC. for more advise. Me I;d say leave the monitor on. Hope this helps.
