Hi, My 2 year old samsung monitor started giving me trouble a couple of months ago. Whencomming out of "sleep mode" I would have to shut the power off and on several times for it to light up the screen.
It would start to light up then go black. After several power on -power off cycles it would work fine.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
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.
sales660, Monitor should not be doing that!!! Use Samsung warranty if available. Complain about "premature failure". Examine black screen for very faint displayed image with aid of bright flashlight(test all owners of CCFL back-lit lcd displays should know) to determine full or partial SMPS shutdown mode. Read more in my fixya profile for more that you can do. It could be bad capacitors or a thermally intermittant solder connection that you or qualified electronics tech will need to fix if warranty not option. After reading and surfing net you will understand your CCFL back-lit lcd display and how it works. Your monitor no different than ANY other brand of CCFL back-lit lcd monitor in it's basic design and operation!!! 12fixlouie
you need your power supply reaired. the capacitors go bad. remove the covers and look at the power supply reeplace any leaking and or crowned capacitors
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.
