    tried different sources. Even with no source, should you not be able to see the menu when you press MENU?

    I see nothing. It's like no video signal is going through to the LCD display.

    Have you verified that the video source is working correctly and that you have set the monitor to the correct input?

blue screen means 'no signal' or 'signal level is too low' whereas black screen means that there's a signal. Check your antennae, do a factory reset to your unit and then try initial setup.

Monitor will not turn on


Capacitors in the power supply or inverter are begining to fail. If the monitor has a few thousand hours on it, the tubes may be close to the end of their service life as well.

If you open the unit up, look for bulged or leaking capacitors- when they leak it is a dark brown or black residue.

Unless the unit is rather new, it may not be a cost effective repair unless you have the patience to do the work yourself..

Guest, You will need to "sub-in" a known-good monitor to prove your pc is working ok! If pc is ok, then plug-in bad lcd monitor and check ( test ) it with aid of a bright flashlight to see if you can see a very faint image of the WIN-desktop being displayed on the now "black" LCD panel. Every owner of "cold-cathode-fluorescent-lamp back-lit lcd monitors should know the "flashlight test" and understand what the results of this very basic test mean. Do some reading in my old (louie12fix) profile to learn how to do test. Hint: The very first thing I would investigate inside the unit would be the unit's "switch-mode-AC to DC-power-supply/ccfl electronic ballast circuit for the top two causes of power supply going into "partial or full" shutdown mode, trying to SAVE itself from a nonrecoverable catastrophic failure. e.g. sparks,smoke, fire!! 12fixlouie

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.

My samsung NW920 turns off after 1 min


If the blue LED ist blinking the monitor does not receive a video/sync signal. If the blue LED is on continuously and the display comes on for a few seconds and then goes dark or dim the backlight inverter may well be defective. The CCFL of the backlight needs several hundred volts to function.
