Following a thread already posted with the same title I noticed that it was resolved because the motherboard was faulty which was discovered after the subject found there were no A B C D lights on on the reverse of the Base Unit. I have the standard DELL PC with  no modifications and it has been working fine for the last 3 -4 years I have had the PC. Now I can't get the monitor to come out of power saver and all of the 4 x A B C D LEDS on the back of the base unit are lit and green. Can you help please?

Don't think the monitor is the problem. When I unplug the VGA cable the monitor goes into self test, the on/off switch goes from amber to green and I get a picture of a small box with Red, Green, Blue and white boxes and a DELL notice that it is self testing the monitor. This confirms that the monitor itself is fine as it can produce a picture, it also confirms that the power supply is ok too. I suspect the VGA driver because when I connect the cable back to the base unit the on/off switch goes back to amber and when pressing the menu button on the monitor a notice comes up on the screen in white letters saying "monitor is in power saving mode, press nay key on keyboard or move the mouse" but doing either of these things has no affect.

Just went to unplug the monitor to try it on another PC and whilst moving it the power button wnet to green and the picture came up. On moving the monitor around I managed to get the picture to go on/off depending on how I moved it. It looks like I may have a dry joint somewhere on the VGA connector - either the cable or within the monitor itself. I will replace the cable to see if that resolved the problem, if not it will be iwthin the monitor connector in which case I will have to take the back off and re-solder all of the pins.

Thanks for the help.
