punchjackson, You or qualified electronics technician will need to open and visually inspect switch-mode-power-supply board to possibly determine cause of SMPS going into partial or full shutdown mode. Do some reading in fixya profile of "louie12fix" and then visit links you find there. Remember this!!! The basic design and operation of your 204B isn't any different than any other "cold cathode fluorescent-lamp" back-lit LCD monitor. Inspect all solder joints and electrolytic filter capacitors first. Then let us know what you find. Also do a visit to YOUTUBE for lcd monitor repair videos and see what a Bad Capacitor looks like before you open your unit. 12fixlouie

1. this may be due to cable select and or cable not being secure at connection point
2.check your instruction manual for proper setup for digital signal to the LCD monitor and the to your video source.

Sir,
You are suggested to check if you serial cable is in fine condition and it properly pluged into the Monitor and VGA. and do also try changing the serial cable .

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

There is a component failure on the board inside the display. Since you did not post the model number that is all that I can tell you.

The monitor convergance adjustment is out . Is it a LCD or CRT

No, it is not the electricity in your house, I had the same problem. Send it back to Samsung and get a new one. I have had to send my monitor back 4 times!
