Question about LG Flatron L1951S 19" LCD Flat Panel Monitor
I have a flatiron monitor that is attached to my laptop. It was working fine; after I was away for two weeks, monitor starts into windows but then immediately goes into power saving mode and image defaults to my laptop screen.
I have an LG W2261V, and an old Sharp LL-T19D1-H. The PC runs both just fine, and the PSU has plenty of power. Unfortunately the LG handles power save mode very differently, where the LG would not switch on after entering this mode unless reset (unplugged, PC rebooted, etc). Extremely frustrating, as the old Sharp never had any problems exiting its own power save mode. The LG would enter this mode based on the monitor power settings (in whatever power scheme you are using) in the screensaver tab in display properties. I fixed this by selecting "Never" for "the Turn off monitor" property. I guess this is a warning to those who may wish to buy a new LG monitor, but want to use a power scheme to turn off the monitor.

I had the same problem on LG monitor too. the problem started when I accidentally bump my computer's desk. i can not see anything on my monitor because my monitor went automatically into power saving mode and i can not fix the problem with the keyboard or mouse because i don't have any PS2 on my CPU. WHen I try to open my CPU there will be this beep sound twice. So I try to check and reinstalled the memory and the VGA card and it miraculously make my computer active again. I hope my experience will be useful to the others.

It's an LCD so the problem is most likely the back-light inverter board. Take a flashlight and shine it directly into the screen from the front. Can you see the image on the screen now? If the image is there but you can't see it without the flashlight than the inverter board needs to be replaced. This is a VERY common problem. Good Luck and let me know what happens, His Dudeness

When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.
But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Check the display settings of your video card. This can be done by right clicking on the desktop and selecting properties. Then go to the settings button and clicking advanced. All video cards are different, but there should be a tab there that will allow you to configure how you want to monitor to be utilized (mirror of laptop screen or extenstion of laptop screen). Often times, laptops have a button to toggle between modes (Example, DEll is Fn F8).

Laptops often have a function key which switches from laptop only, external monitor only, laptop & external. One of the top number keys, along with the function (fn for short) must be pressed simultaneously to step through these.
Where these keys are at, may differ from laptop to laptop.
