How do I open my Samsung 2233sw LCD monitor? I need to open it because something is lose inside going all over the place and I don't want it to short out.

Hi!.
This sounds like the input setting on your monitor is incorrect and the setting is defined by the type of connection you are is useing from the computer to the monitor (VGA, DVI, HDMI).
A free manual for you monitor can be found here:

I would make sure my video drivers adapters are up to date. Use windows update to automatically set the proper driver to the display and to your video adapter.

try to change the plug adapter if isnt workink you get a problem inside at your monitor and there need it an expert

The "native" resolution of the monitor is the "optimal" resolution -- it looks best to use this resolution.

So, right-mouse click anywhere on your Windows desktop "wallpaper".
Click Properties.
Click Settings.
Move the "Screen Resolution" slider to the recommended settings.
Click Apply.
Click OK.

You may want to inspect the DC filter caps in the power supply first.<br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'">If you are going to DIY and have proper tools and know safety precaution then please read on:</span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'">Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps).

I finally got myself the solution of my samsung lcd monitor 2233sw.
The monitor has dvi D input, so I guessed I just had to plug the d-sub cable to the monitor as well, and it worked well so far.
