Has a good picture on startup and fades to black in about 5 seconds. Turn it off and on, the picture returns for another 5 seconds.
The monitor may be failing. Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

I've had a similar problem. I took apart the monitor (it was out of warranty by that time anyway) and found the lamps would not stay on. They'd flash for a split second before remaining unlit. I tried hooking up another LCD monitor's lamp to the Samsung, and even though I knew the other lamps worked fine, they exhibited the same behavior. Looks like something's wrong with the circuitry. The LCD actually does display the desktop on screen correctly. It's just the lamps refusing to stay on.

FIXED: I took the advice to replace C110 and C111 with 1000uF 35V
electrolytics
(http://www.radioshack.com/product/index.jsp?productId=2102511). $3.18
and a pretty easy time prying open the case with a medium-small flathead screwdriver, disconnecting a few connectors, 4 silver screws (2 on the left & 2 on the right of the LCD), 2 black screws on the back of the metal case, 3 black and one brass screw on the PC board, and
it works like new.
HINT: Be sure to insert your new capacitors correctly (positive and negative sides). The capacitor has + and - sides (the - side was marked on mine). The bottom of the PC board (where you apply solder) has a + marked on the positive side.
For the faint of heart: I am an inexperienced and HORRIBLE solderer and know close to nothing about capacitors, resistors, etc. So, if I can do it you can too!!!

Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.

hello i have the same problem, there are 4 lamps (bulbs) inside the monitor when some of them falls the system turn off, cheks and good look

rcpips, You may need to replace one or possibly 5 -8 aluminum can "electrolytic filter capacitors" on the "switch-mode-power-supply/CCFL inverter board. If, as you say "works for 5 or 6 seconds" then that means that fuse is good. Another thing you will need to inspect SMPS board for is "cold" "frosty looking" solder joints where the components (surface mount or through hole) are soldered to the copper circuit traces. May need large magnifying glass or low power inspection microscope to locate them. Resolder any that look bad or loose. Some solder joints have thinner than "hair" thermal fractures that can also cause YOUR TYPE OF SYMPTOM!! PARTS: digikey. mouser. newark. and possibly Radio Shack. If buying filter capacitors, make sure they are rated 105 deg C only!! NOT 85 deg C!!! If caps need to be replaced (swollen, leaky) be sure to tell us the brand name you find installed on your unit! CAPXON, ELITE, JUN-FU are just 3 that you don"t want to find in your unit. BAD news if you do!! If DIY suits you, remember to document with "close-up" digital stills your unit tear-down, so you can reassemble unit without any "extra" parts laying on kitchen table!! Filter capacitors are polarized. You put them in + to +, - to -!!! if you put them in backwards they go BOOOOMMM!!! Hope this helps a little. lmistyrel on aim or 12fixlouie at fixya.
