Lift the front frame. You must try to lift it from the inner side using your fingers (no tools , you may scratch the lcd panel). A little force is necessary especially at the corners. Once you lift the panel from all four sides then the corners will come out.

Note: A common problem with this monitor is the psu. A small number of capacitors fails. You will notice 3 electrolytic capacitors have been deformed and if there is no power you will find a small 3A fuse (looks like a resistor) blown.

The lcd turned black, even though the power button is on


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 :-

LED POWER ONLY LIFE, SCREEN DISPLAY DARKNESS


theres only one solution to the problem you have to replace the whole power supply board .its easier to replace them than finding and soldiering the defective parts like the capacitor on the board .u can just replace the power supply board if u think the power has a problem. if it doesnt work then u have to replace also the main board or the board connecting the rgb cable.its more expensive to replace the board but its worth it. ur lcd will work better and its easy to put them on the lcd casing .

Spare parts


This couldv'e went under here or I have the same problem, unfortunately there aren't dealers selling spare parts unless it's wholesale(in bulk) to another dealer. I know this is going to sound cliche-ish but ebay is the only place where you may get a non working unit that has the part you need for a halfway decent price. Just check with the seller to make sure that the part you need on the unit is working before you purchase.

It sounds like the CCFLs (backlight lamps) in the monitor are failing. You might be able to get them replaced by the manufacturer if it's still within warranty. Otherwise the fix might involve an expensive technician and replacement parts.
