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.

This is the problem in the backlight (Lamps).
Kindly approach Authorised service center because this monitor is covered under warranty.

Hi I Got a Samsung SyncMaster 920NW the display


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

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.
