Your symptom is commonly caused by failure if the inverter circuit. It is made by Sampo. The inverter powers the backlights. Replacing the inverter is the first step to resolve the problem.

If there is green light on monitor.so you just check the vga card and ram.First check both are placed in the slot correctly or not.if it is so then replace new one by one .then you can catch what is the problem.and can fix by urself.

As one of my "initial things to do," I unplugged the monitor and then replugged it in and it did not fix anything. Then after reading others' solutions, I unplugged the monitor and let it sit for about 15 minutes. Once I plugged it back in, it worked just fine. My setup is a laptop with docking station - the monitor in question is attached to the docking station as a dual-screen setup. Though this may not matter technically, it might help those searching for solutions. Thx! Jake

Without much information given as to the state of the monitor - Check the LED on front. If Orange, it's getting power and the has a problem. It could be: Fuse Digital Board Power Supply If Green Check the Video Card on PC If None/Off (with unit unplugged) Sniff & Check the power supply board of the display. for Fuse and Visible damage.

Try, if you can another monitor, if same problem, check graphics card connections(connection to your monitor) and if you are able re seat graphics card. If you have frequent power failures, you probably have power surges, this can be a problem as they can fry various components on the motherboard, check that you are getting 2 beeps from your pc when starting it up, if there isn't, your pc is not booting up and your monitor will probably display an orange light (stand by) instead of green.

I eventually contacted Samsung support and basically it is a component failure so a new unit was supplied under warranty. Unfortunately there was no software fix they had available.

Hope this helps you like what I did to resolve this kinda problem. If you can manage to open the chassis/cover check first if the HOT (horizontal output transistor) is good, if good check the SMPS (switching mode power supply) primary and secondary side if there are short filter capacitors, diodes, transistors and open resistors. Major faults to consider is by checking the load of SMPS, control circuit, driver circuit, feedback ckt.
Please let somebody to assist you (a certified technician) how to open the chassis safely due to electric shock. Please be guided accordingly.

Try to plug into another computer and wait to see.
If it turn up to be same it somewhere defect from the main board of the lcd.
If if not the same turn up to be, you should reinstall the OS because the software is corrupted or your display card problem.
