Samsung 740n monitor gives dulled picture for about 2 seconds with a whitenoise sound then instantly fades to a ghost image behind a black foreground with no whitenoise. When I press the standby button to turn it off then turn it on again, same problem.

My Samsung SyncMaster 740N occasionally turns itself off. Timing varies and the condition varies. Usually the screen just goes black - from seconds to hours after it is turned on - the blue LED remains...


This could be because of the 'eco' friendliness of the monitor. Basically a lot of monitors are designed to turn off into a low power state when not in use so to preserve power and life of the monitor. I would return the monitor as the sensors that control this seem to be broken in your monitor.

I would inspect all the caps, if you find even one bulging top/leak you should replace them as a set.
See failed SAMSUNG here, use good caps, such as PANASONIC FM or FC series from DIGIKEY.

Well in monitor you can do one thing - disconnect the monitor cable*(VGA Cable) from the tower and chk still if u have the same faint screen that means monitor gone bad if not than uninstall the Grapics Driver and shut down computer... if u have internet than restart and go to device manager ( Run - devmgmt.msc) under display adapter right click on grapics name and update driver.

Syncmaster 740n was working fine but has not gone black when i turned it on this morning and now i cant see anything, ive put it onto another computer but its still black and not showing anything sumtimes...


Hello,

This sounds like the inverter power supply has gone out. This is a very common problem for LCD monitors after a few years.In the 740N monitors they used two different power supplies but both had the same problems. If you can open the monitor and take a few pictures of the board and email them to me at tech@ccl-la.com I will tell you what needs to be done on that version of board. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping.
