Re: monitor goes black
If U can see the cursor then your monitor is fine, the culprit is your graphics card. It could be a virus, or a driver error. Try installing the drivers and check for viruses, if no help then Your graphic card is the most likely fault

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.
disconnect all the cable from the monitor except the power cable .
see if you see any test screen and keep it on ,if the test screen blacks out you monitor is bad ,better buy a new one as usually repairs cud be expensive
First--was it working? Did it suddenly stop? When you see the LG logo, then it goes away, does the power light turn from green to amber? Sounds like that doesn't happen. So--if you are getting a signal, you should see something. If there is no signal, then the power light should change from green to orange. With no lights at all, I suspect a faulty monitor.
"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.
Check to see if the image is Dimmed. Chances are the power supply on the FPD is either dead or not supplying power to the back lights.
Your problem is the power supply or the inverter on your board, you can replace it and it will be fixed. Easy Fix REALLY EASY FIX (inverter is what supplies power to your backlights. A lot of the times the reason a monitor goes black and the green power button is on, is because the backlights shut off. in most designs of the 1730 the inverter is embedded on the power supply. That is most often the case on this problem. Power supply/Inverter=Replace it and you will have a spanking new looking nice monitor working again. :)
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.
Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!
