Question about Samsung Computers & Internet
I don't know which monitor that you own, since you did not supply that information. So I will assume this is an LCD monitor. Typically problems are with the digital board or the backlight circuit board. If it is the digital board, the only reasonable way to repair it to find a replacement board.
To determine which board is bad, take a flashlight and shine it on the LCD. If you can see any kind of image, it means that the digital board is working and the problem is with the backlight.
I don't know if you are technical, what I mean is are you able to open monitor and check the components with a meter and know how to use a soldering iron. If this is beyond your ability, then I would advise you to take it to a repair shop and they should be able to fix it for you.
If you have the technical ability, then the problems with the backlight are usually the capacitors that fail and blow, fuses, transistors and the backlight itself that go bad.
Open the case, and find the the power supply board, it will be the one with the large capacitors. Look at the board for any burned or heat damaged parts. If none are found check the capacitors first. If any look bloated or have the tops of the capacitor blown open, then they should be replaced with the same capacity and at least the same working voltage as the damage one.
Fuses should be checked for continuity if the caps look good. If the caps and fuses are good, then check the transistors. Often the transistors fail by short out.
Let me know if you need any more detail on how to troubleshoot by leaving a comment. Also, if you supply the model number, it can help me be more specific about your situation. Hope this helps you.
