I have had the same problem with two of these monitors. If it is not still covered under warranty, start by opening the case. Once you remove the power board, you will probably notice several capacitors (the round, can shaped parts) that have tops that are not flat. If you see any that have bubbled tops instead of being completely flat, they need replaced. Once they are replaced, the monitor should turn right back on. Hope this helps.

According to the CD manual, you have to

1. Push the source button on the bottom of the monitor and then
2. Proceed as if you were bringing it back from sleep mode.

It worked for me.

Hello,

The picture board of your monitor has developed fault. That is why the screen is black.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity, because the fault is not something you can fix in other not to complicate issues..

The repairer will help diagnose and replace the faulty picture board and your monitor is back and better.

Take care.

Check out the power supply section first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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.
