If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

When you turn off the pc the monitor loses the sync signal and should go into a suspend mode where the screen is blanked. The power management settings should be checked. In display properties check that the monitor is installed correctly.

in the back of the monitor your going to see holes that go in deep, all of these holes will have screws in them. Use a phillips head screwdriver to unscrew these screws. There will be some on the top, bottom and possibly on the sides.

Take out all of the screws and then the back should come right off.

Degausing may not be working in your monitor. If you can get a degausing tool you can manually do the degausing.

Thank you so much for responding so quickly, I actually sent an email to Samsung (after much searching I located information on the monitor ) and they sent the manual in power point. I was able to unlock the screen and reset the size center the screen. If you would like I can send the manual to you so you have it to pass along to any one else.

Apparently what you need are the wiring for the VGA cable itself. They would differ from manufacturer to manufacturer since it is not a Samsung item. Would the schematic and/or Service Manual of the Samsung chassis AN17K (753DFX, 76DF, 753V, 753S, 76V or 76E) help? if so, pls try here, here or here.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

First, be aware that the flyback xformer can carry a 50,000 volt charge that can arc to anything grounded. Unless you are possitive the chasis is not hot, I'd forgo pulling it apart.

That said, if you turn the monitor on its face and remove the stand. You'll see two screws on the bottom corners of the monitor housing. Remove them. Next, turn the monitor upright with the screen facing you. you'll see two VERY small openings along the top edge of the monitor bezel. Insert a small flat-headed screw driver into each opening, and press gently down. You should hear the locking tabs release. DO NOT pry the case as you will damge it. With the screws out and tabs released, the case will easily break apart.
