From the description one of the inverter transformers have failed, located on the power supply/inverter board.

Does it show a picture in safe mode? If it does you might want to install drivers specific to the Monitor if you can find them.

The screen displays is dark/ dim because there is no backlight.
There are two parts responsible for lighting the display. First is the CCFL (Cold Cathode Florecent Lamp), which is the back light and the second is the Inverter board, which provides high voltage to the CCFL. Either of the parts can be faulty or in some rare cases both. In most of such cases that I received for repair, it was Invertor. Inspect the Invertor for any apparant physical damages (burnt coil or circuit components etc). Inverter can be checked by disconnecting the present CCFL and connecting a fresh/ working CCFL (Backlight) before actually removing the CCFL as it is difficult and unnecessary to take it out if its not the fault.

I SUGGEST THAT YOU SEEK PROFESSIONAL ASSISTANCE FROM AUTHORISED SERVICE/ REPAIR CENTER FOR REPLACEMENT OF CCFL OR INVERTER.

Hope it helps! Good Luck!

First, connect this monitor to another computer, if you still do not get a Windows image on the Samsung LCD monitor then it is faulty. The fault could be a faulty inverter board that supplies high voltage to the CCFL lamp or the fault could be a faulty CCFL lamp.
Parts for this monitor could be avaiable from LCD Parts, theie WEB site is :-

Problem seems to be hardware related ie monitor itself is defective.Try connecting to another known working system.If monitor is defective it could be a power/inverter related issue or panel could be defective.

Reset satellite data and the flickering went away.

buy a new monitor

It might be the connection loose of power cord problem or check your TFT power connector inside the TFT if you can open the TFT screen!!! It may be dry solder….
Other wise go to repairer and do the same….!!!

The connecting cable or the video card would be the first suspects. Try a different cable to connect the monitor first, if there is no change, the video card in the computer would be second to look at. Can simply connect a different monitor to your computer to troubleshoot this. If the testing monitor works, it will be the graphics card that is the issue.
