My samsung 204B monitor does not come on and the power button blinks green continuously on the front

Hello,

This is a common problem with the Samsung 204B units that have been in service for a few years. Parts called capacitors in the power supply start failing and causing the board to not start correctly. The blinking power button is just the power supply restarting over and over. The monitor is easily repairable, you just need to replace the 5 capacitors that have failed. Here is a link to a page that shows how to open the monitor, get to the power supply board and what to replace.

I hope this helps, if so please rate my solution.

REPLACE THE POWER ADAPTER!

Replace the screen with a known working one. If it shows display then it is the screen which is broken, if not, then it could be the port on which it is connected.

Have you tried to plug it in else where?
If you did and still same problem then from what you said I was hopping that it wouldn't be your problem, but you will need a new monitor.

I too have a dual monitor Samsung SyncMaster 204 setup. My monitors started flickering, then a week later had turn on problems like your describe. I found a fix on this fixya website and followed the fairly techie suggestion. It worked. I wrote up a .pdf set of instructions so others might also benefit. Hope this helps. Doug

If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.
