You lift up the front bezel, just go around the bezel but do not completely remove it, just on three side, then lay it face down and snap up the back cover. Be real careful with the cable attached to the front bezel.

If you are saying that it powers off in a few seconds you most probably have a bad (internal) power supply.

Check the DC filter caps in the power supply-inverter section first.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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.

My monitor syncmaster 920nw hissing with power and diod not shine


I will suggest not to plug this monitor into the AC outlet until you open it up and inspect the inside before more damages are done.
First palce to look will be he capacitors in the power supply, look for bad caps with bulging top/seal or leaking, burnt parts, loose connection, etc.

Yes, More than likely the problem with the unit is blown capacitors on the power supply board, the flashing power light is a good indicator of this type of failure. Here is a link to a repair guide with pictures and videos showing how to open the unit and what to look for and replace to get it back going again.

Dark screen samsung syncmaster 920 N strange noise behind it


The clicking sound you hear is the power supply board trying to start up, this indicates the board has failed. This is a common problem with all LCD monitors after a few years of use. Parts called capacitors on the power supply board fail and they will keep the power supply from starting up correctly. If you can solder then you can repair the board yourself. Here is a link to a repair guide with pictures and videos showing how to dis-assemble the unit and then what to look for and replace to rebuild the board and get the unit back running.

Samsung SyncMaster 920nw suddenly went black now squeaks/flickers


The 920nw did have a 3 year warranty on the unit but they will be out of warranty now. The flickering power light is an indication of a failure in the power supply board. When the board fails it can't start up correctly and the power shuts down over and over so you get the blinking light and no display. This is a very common failure point on all LCD monitors after a few years of use. There are parts called capacitors on the power supply board and they filter the output power. When they fail the power is not properly regulated and the power supply shuts down and tried to restart so you get the flashing. Here is a link to a repair guide that will show you how to dis-assemble the unit and then what to look for and replace to get it back up and running again.
