Check the backlight inverter board, may have blown fuse or shorted out transistors, bad caps.
If you are going to DIY 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, blown fuses; poor solder joints, 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 monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

I had the same problem with this monitor (Samsung 943nw)
When turned on it would only stay on for less then a full second.
When shining a light on the screen I could see what was on it, so it was just the backlight that was shutting down.

After I turned down the brightness of the monitor, the next time I powered on the screen the backlight stayed lit and it was back to normal.

Samsung syncmaster 931a... connected to computer


Hi, its unlikely to be the cable. Most likely cause of this is a faulty inverter board. If you are lucky it will only be 1 or 2 blown capacitors which are easily identifiable and replaceable once you have got inside it. it could however, be almost any of the components on the inverter board or even a failed backlight but this will require further testing and a knowledge of LCD monitor workings.

Used as second monitor suddenly stared to go dark


If the screen is lighting up for a fraction of a second when you turn on & then goes dark, this indicates a fault either with the backlights on the screen or the inverter part of the monitor. You can check the backlights if you have access to a backlight tester, you need to remove the rear cover & connect the backlight cables into the tester, if this checks ok then look for a problem on the inverter board, checking the capacitors for any signs of distress.

It may be the back light on the monitor going out.
If you turn off the lights in the room, close the blinds & curtains can you see any image on the screen?
If so then it is the backlight. it is sort of a fluorescent light in the monitor that will go out over time or if gets jolted too many times.
Check repair cost first it may be best to replace it. I saw 22" monitors on tigerdirect.com for less than $150.
Turn off monitors when not in use. there is a limited time on anything just like a light bulb gives up after so many hours.

Monitor goes on then off right away.


The backlight inverter is faulty.
THis means that there is either a loose contact or one of the transistors on the backlight inverter has blown

My display on the lcd monitor goes blank after startup.


It sounds like a backlight problem. It could be a problem with the inverter board or backlight itself. When the display "blanks out," can you still see a faint image on the screen -- especially if you look at an angle with some light shining on the screen? It is usually easiest to see changes on the screen - so after Windows boots, press the windows key on the keyboard repeatedly and look at the part of the screen where the start menu would appear. If you can see anyting, then it is definitely a backlight problem.

If it is a backlight problem, you'll need to disassemble the LCD panel to correct it. Correcting it might be as simple as re-seating or re-routing a loose or pinched backlight cable to as complex as replacing the LCD panel and inverter board. There is really no way to tell over the Internet. You'll probably void any applicable warranty by disassembling the panel.

By the way -- watch out, the inverter board can generate lots of voltage and reasonible amounts of current. I've never been shocked by one, but I've been careful.

Flat screen monitor


Possibly a bad inverter that turns on the fluorescent backlight or a bad bulb.

Monitor is completely black


Could be a problem with the LCD backlight or the LCD ribbon connector fault. I would recommend taking it to a tech to get it serviced.

RE:monitor goes black


Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
