That's indicated your backlight inverter are busted. Need to replaced a new one or repaired it. To repaired look for a bad capacitors with a bulged on top of each caps. Not sure, just replaced all the caps... Have a nice weekend!

Its the capacitors on the backlight power supply. Samsung installed crappy ones and they blow up after a year or two. Change out the caps and you're good to go

Your monitor has a very common problem. The internal power supply has blown a part called a capacitor. If you are comfortable working with electronics and with soldering I can talk you thru the diag/repair. If you are not ready to tackle that we also offer a repair service, about $30 plus shipping for your model. Let me know if you want to try fixing it yourself and we can go from there. The repair will require opening the monitor case and replacing from 2 - 5 parts. You can call me at 318-447-9040 if you have questions.

SOURCE: flicker then display goes black
My samsung syncmaster 225bw when turned on would have the back light stay on for about one second, then go black, with or without the signal cable attached to the computer. After your screen goes black, shine a flash light on the screen to see if you can see any images
I repaired my monitor by replacing several bad electrolitic capacitors on the inverter board. These capacitors had broken bulging leaking vents on ther tops. There were two 820uf 25v and one 330uf 25v electrolitic capacitors that had failed. I ordered from www.digikey.com Panasonic FC series low impedance electrolitic capacitors, However, the 820uf was not curently stocked and had to be backordered, so I got one 1000uf and one 680uf to replace the two 820uf which were in parallel on the board. There were two 680uf 25v on my board which had not yet failed, so I also replaced them. On my monitor, the capacitors can not be longer than 20mm, due to space limitations. These electrolitic capacitors have a life time between 1000 to 5000 hours, so when you order get a few extra of the ones that went bad.

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.
