Hi I Got a Samsung SyncMaster 920NW the display

Replace the video cable or hdmi,depending on which you may be using. Some of the small wires in that cable may have snapped. Another suggestion is to take it into a repair shop that gives free examinations or diagnosis, because one of the small leads going from the screen to circuit boards lining the display, may have broke, unfortunatelly this may lead to you having to buy a new display. Most of the time it can not be reconnected due to many wires in the same ribbon are to close. You may also have to purchase a new screen from the factory.

I have the very same problem and I have no knowledge of the backlights of LCD panels. Is there any way to fix this yourself?

BENQ Q7C4 monitor shuts down after 5 seconds of login screen display

Most common cause of the failed monitors are bad caps in the power supply, if it is about two years old, I would open it up and look for bad caps first, then look for any burnt parts, post back so we can guide you further, see failed SAMSUNG monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

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.

Samsung syncmaster 920nw 19 goes black after 2 seconds

Could be a power issue. If it doesn't show anything at all then that may be the case. It may also be the display itself. It would be a costly repair so you might be better off finding a new monitor.

This is due to backlite problem of LCD panel.
You may approach authorised service center for this issue they will solve your problem. Do not try to do yourself unless you have sufficient experience on LCDS.

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. Look in our monitor repair section for step by step repair guide for this model it should be the same power supply as the 930. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.
