You have to
check if you can see the image on the screen or not after it went blank (Power on both CPU and monitor) by shining a flashlight into the
screen, not directly but find the best angle to the screen and take a look very
closely. If you can see the icons or any image, there will be a minor problem.
Like mine, I can see window image using flashlight and check lamps inside. Some
of them were broken and it is very easy to replace. If you cannot see anything on
the screen, there'll be some problems with inverter board. If you have
soldering tool and want to fix it by yourself, check the caps first. It may
cause this problem. Some caps might show leaking or burn spot on the board
because of too high temp. If you don't have soldering tool, you better go get a
technician to do so.

Solution for Samsung SyncMaster 2232BWplus:
The problem is bad capacitors: 5 pcs. 820microFarad – 25v and 1 pc. 330microFarad -25v. Replace these capacitors. Then re-solder the two transformers of inverter side. Also re-solder the power transformer and the inductor coil.
To open the casing:
At the bottom of the stand just twist the knob to unlock. Then, use a small flat screw driver beginning from the bottom (left or right) then using a hard credit card (or alike) then slide/glide it in between the cover plastics.

This model was released in 2001, you need to open it up and look for bad caps with bulging top first, the problem can also be in the backlight inverter circuits. Post back what you see so we can guide you further, see example of failed SAMSUNG monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
