Look for bad caps (leaking/bulging tops) as shown in my albums, it is very common problem on all brands of LCD monitors.
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.

My Samsung syncmaster 2220WM will not stay on. It


Hello,

The picture board on your monitor has been malfunctioning for quite the period but you did not notice it, since the screen goes blank, it means the picture board of your monitor has developed fault and will need to be replaced.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Hello,

Call and get the RMA for your monitor, the problem is in the power supply and it will only get worse. This is a common problem with LCD monitors after 2-3 years of use.

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.

Samsung Syncmaster 204T flashing


Hi,
Please check that all the cables are plugged in firmly on the back of the monitor and on the back of the computer.
However....
It sounds like the back light on the screen is faulty. If this is the case it is definitely a return for repair problem. You should be able to find the warrantly procedure for your area on the samsung website.
Cheers
Dave
