I saw this problem described in another posting but the answer was not appropriate. The problem occurs after the monitor is turned on the screen last only a second or 2 and then goes very dim to the point that it is barely visible. When the monitor is turned off and on again, the cycle repeats. This occurs independent of the computer as I can pull the serial cable and get the standard "no input" color adjustment screen for a second and then it goes dim

Re: Monitor goes blank
Sounds like the back light inverter board is bad.
It's a very common problem.
LCD's use four small cold compact fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it)
The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display.
If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad.
The inverter board and CCFL's are replaceable.

Re: Monitor goes blank
Monitor goes blank?
This trouble maybe power supply or inverter boards is defective.
first you can test the voltage of the multr,and then check which part is defective.From Wisiny.com can find those parts

It is a little tricky problem. But anyways this is due to small capacitor leak you have to replace it to make it work well. You can identify it by seeing the top of it. See the below pix for more info.
Hi Rick, is it a "CRT" type of display, or "LCD/LED" ??
The symptons sound like the latter, I have answered a similar post earler on here, it could be capacitors stopping the back light from comming on, if you are able, check them, and replace (all) of them, its a good starting point see web for videos to help you.
If you are not good with a soldering iron & cap tester, best NOT start on this screen.
Be mindfull of high voltages, and being killed.
Just saying Rick.
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 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.
mhaupt, Tell me if it is both BLACK and BLANK or just BLACK after you do the flashlight trick !!! This is no joke!! understand?? When the screen goes black hold bright flashlight where you saw an image on the screen (icon or win start button) and tell me what you see or don't see!!

Luckily I'm not in it for the money so here's your answer. (Sorry drumbanger.)
When it goes black, look at your power button. Is it still green? If so, the backlight display is bad. If the power light has turned orange, you're most likely looking at a power/inverter problem. Sadly, if you don't have another monitor that you can swap parts out with, you're looking at a new monitor. But with the economy on the downslide, replacements keep getting cheaper! Research online and you'll find some fantastic deals! Rate me if you find this helpful.
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
Click start, then then control panel and click on the power management icon. When you see the screen, look at the power management "scheme" and pick the appropriate setting. I assume that what you are experiencing is what's known as "Power management" . In order to achieve an "Energy Star" rating, the computer must shut off various components to conserve power. If you don't want to have your monitor shut down, select never from the options in the Power Management screen. Thanks for using Fixya.com
The video resolution and/or frequency that's set in windows is not supported by the monitor you have plugged in. Restart the PC in VGA mode (hit F8 after the BIOS messages but before any Windows messages) and change the video settings to something basic, such as 800 x 600 @ 60 Hz. Then restart the machine normally.
Ok sounds to me like a power supply problem.. this a a fairly common symptom. I suggest that as a temporary fix you set the monitor to NOT turn the power off to the monitor in sleep mode if possible, in your power settings for the monitor.
