Question about LG Flatron F700P 17" CRT Monitor
Hi this is the way how to examine what's wrong with
your LCD monitors. After you turned it on and the screen blacked out, you have
to check that if you can see the image on the screen or not by shining a
flashlight into the screen, not directly but find the best angle to the screen
and take a look very closely. If you can see the icons or any image, there will
be a minor problem. This is because of the lamps inside screen. Some of them
were broken and it is very easy to replace. If you cannot see anything on the
screen, there'll be some problems with inverter board.
Hope this help!! If anything I can
help you with, feel free to let me know.

Hi atieh, How long does your monitor stay on after you push the screen-power button? And after it turned off by itself, you go check the image on screen without pushing any button by using my method above (USING FLASHLIGHT). The inverter board is the circuit board inside the monitor. This board controls monitor power, signal input and output from VGA card. If there is something wrong with CCFL lamps, it will shut down by itself because of circuit safety. As I mentioned last time, it is not too difficult to change the lamps. Could you tell me the specification or data sheet of your monitor?

Tips for a great answer:
you plug in the power cord is there any lights whatsoever on the computer?
When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).
Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.
you have a Static Charge Buildup. Remove the Power Cord, then Press and
Hold the power button for 30 seconds. After 30 seconds plug the power
cord back in and hit the power button to see if it boots.
your memory is bad or the memory slot is bad.
the Power Cord, Open the Case and remove one of the memory chips. Set the
chip aside then try rebooting the computer. If it boots, then you know
the memory chip you set aside is bad so mark an x on it with an ink pen.
If it fails to boot then move the chip to the next memory slot and try
rebooting. If it fails take the chip out and set it aside, then put the
other chip in and try booting it in both slots. If it boots, just to
verify that the chip set aside is bad, mark an x on it and put it into the open
memory chip slot and try booting.
your power supply is bad. Sometimes there is enough power to make the
power light or some other lights come on but not enough power to make the fan
turn on or hard drive spin.
Below are links and info I found from Dell's Website based on your model.

four lights on the front panel (see Diagnostic Lights.)
