When computer (Mac Pro) is left on but not used for a long period of time, screen shuts down and when mouse or keyboard is used to ''wake the screen,'' it can take up to 10 minutes for the display to emerge. If I cycle the LCD's on/off switch, the display appears for 1-2 seconds and then disappears until sometimes 10 minutes has elapsed. During this wait, with the right amount of glare on the screen, I can see a faint image on the screen where I can see the mouse/programs act corresponding to mouse/keyboard imput.
It is leaning towards your screen is going out and needs replaced.
SOURCE: green line vertical on screen keeps appearing
in the monitor menu button you will be having a option called "degauss" give that when it appears ...
if you still persist the same problem then there may be some problem in the CRT tube ....
just take your monitor to the technician ...

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
SOURCE: Monitor cycles on and off. There is a display, but
Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, falied 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 goes wrong: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

You probably have caps failing in the power supply.
