Check the DC filter caps in the power supply-inverter section first.
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 (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). 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
Post back what you see inside so we can guide you further and it will help out other people in the future also.

I have a samsung syncmaster 943NW which goes on for about 5 seconds and then just goes black. When restarting the screen it does the same again, goes on for about 5 seconds and then black. Is there...


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.

Hi I Got a Samsung SyncMaster 920NW the display


If you are saying that it powers off in a few seconds you most probably have a bad (internal) power supply.

Samsung SyncMaster 920nw suddenly went black now squeaks/flickers


The 920nw did have a 3 year warranty on the unit but they will be out of warranty now. The flickering power light is an indication of a failure in the power supply board. When the board fails it can't start up correctly and the power shuts down over and over so you get the blinking light and no display. This is a very common failure point on all LCD monitors after a few years of use. There are parts called capacitors on the power supply board and they filter the output power. When they fail the power is not properly regulated and the power supply shuts down and tried to restart so you get the flashing. Here is a link to a repair guide that will show you how to dis-assemble the unit and then what to look for and replace to get it back up and running again.

My samsung syncmaster won't start. It stays black (the light on the power on button is green). If I try to power it off and on again, I can see my desktop for a few seconds then it beeps and die.


Hi:
You have a problem with the power supply that is built into the monitor. These are not easily repaired, as the cost exceeds the value of the monitor.

Monitor goes blank after 3 seconds -Samsung SyncMaster 920NW


Could be a power issue. If it doesn't show anything at all then that may be the case. It may also be the display itself. It would be a costly repair so you might be better off finding a new monitor.

Monitor turns off after about 3-5 seconds


I would say your monitor is bad if you have tried it on 2 different monitors and it does the same on both. Check your warranty expiration date, some monitors have 2 or 3 years warranty. If it's still under warranty, you may be able to have it replaced or repaired.

This is due to backlite problem of LCD panel.
You may approach authorised service center for this issue they will solve your problem. Do not try to do yourself unless you have sufficient experience on LCDS.
