Check the secondary section, something is short. not sure what it is may be 5 volts regulator exceed voltage, EHT transformer drive transistors are short (some used the SMD) or may be the Power supply is not giving proper voltage (not able to take load).

power save mode indicates no input signal. Check the input signal with a known good monitor. if the signal is good then dell monitor is faulty. Power cycle (unplug the power then plug it back in) the monitor to reset to factory and if it still goes directly into power save mode the unit is faulty.
I don't know if there is a monitor with a function button to turn off the power save mode. As far as I know the power save mode of the monitor can be found in the display setting of the windows..
Anyway... If you want to turn off the power save mode of the monitor via windows display setting then here is what you need to do:
On control panel, double click display settings.. click the screen saver tab... on the lower portion Press the "power" button.. Select power schemes tab.. Change the settings of" turn the monitor off" to "never" Click apply and then OK..
Hope it gave you an idea.. Much appreciated if you rate this help...thanks..
Hmmm...Stuck in power save. I guess when you push the power button, the monitor says power save, then blanks to power save, no matter if the Computer is on or not. This means the monitor does not see any signal from the computer. I would suspect the computer first. Try a different monitor (borrow one). If the size of the monitor picture is too high and the monitor is an older LCD, you may have set the image size too high (1280x1024 will not work with this monitor and it will do this very thing). A broken or damaged connector cable to the monitor can also cause this. Was the monitor unplugged from the computer just before this problem?
you talk about a dell monitor but categorised under LG monitor...
if it's a Dell monitor, and its recent, it's possible you've put it in analog/digital mode when you need the other mode.
push the left button on te front of your screen that should switch your screen from digital to analog or vice versa
I had the same problem and I went to the first button on the monitor to the left(main menu) then with the button to the right (-) I scrolled down to factory reset. I also did the osd setting and I'm not sure what fixed it, but I havn't had the problem sence.
Reset factory settings. Push the selection button (second button from the left at the bottom of the monitor, next to the AUTO button), then go the the Factory Reset by pressing the minus button. Press the selection button again, and when it asks if you want to reset say YES by using the minus button. It's a quick fix!
