Most failure in LCD monitors are due to cheaply made caps being use. If you are going to DIY repair, please read below, or if you are going to have it fixed then at least you will know if you are being ripoff or not.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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

When you have strange functioning going on, first place to check will be the power supply.

Hello,This is a sure indication of a failure in the filter capacitors on the power supply board. Here is a link to an article about repairing that power board, it is used in the 930b and 720 models too.http://www.ccl-la.com/blog/index.php/samsung-930-and-720-series-repair/

reset the picture settings back to default. No more flickering and no more black outs! Give it a try... perhaps it works for you thx

I don't think your LCD has internal speakers. Does it have a small 3.5mm jack with a speaker symbol (like a headphone jack)? I was looking at a review of your model and there was no speakers listed on the specs.

check for correct vga cable connection

Look for bad caps with domed tops, see my pictures here:

If you are going to DIY and already try the monitor with another PC, 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).

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

I encounterred that same problem before. I just changed the video card cause it was corrupted.

this is probably a fault with the internal power supply or the backlight inside of the monitor. in certain Samsung monitors the capacitors go bad in the power supply, these can be replaced by re-soldering identical ones to the power board, which is fairly easy to do if you know how to solder. if that isn't the problem, the back lights have gone bad, which is very dificuly and probably expensive to replace. However, the monitor could be fine and you could have just altered the brightness/contrast or some other settings in the menu on the monitor itself, you could try selecting the factory reset option if it has one. Another thing that could go wrong is if someone has messed with the display calibration settings on the computer itself (unlikely).

Most likely a VGA cable or DVI cable. I would place my bets on a VGA cable (both ends are blue).

Metric screw M4 0.7mm Pitch, the length will be depended on the thickness of the mounting plate, try HD or LOWE's.
Notes; watch out for the DC filter caps to go out in this monitor.
