Question about Samsung SyncMaster 740N 17" LCD Monitor

1 Answer

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 lit - and if I touch any Button on the monitor (except power), the picture returns to normal. The one vartiation is that sometimes it powers down - off. In that situation I see that the blue 'on' LED isn't lit, so I press the power button and everything returns to normal.

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.

Where is degausses key on my monitor"


LCD monitors don't have degauss buttons. Degaussing was needed with CRT monitors because a magnetic charge would build up on the screen and need to be reset occasionally, though in later CRTs this was done automatically whenever you turned the monitor on.

I have a samsung syncmaster 740 N screen, and it's dead (the power light is on, and the screen remains black, no "no signal" indication or anything). my warranty has expired. is there anything i can do ?...


Open it up and check the caps in the power supply. Check to see if the tops of the cans are bulging. Look to see if there leakage coming from any cap. If the caps are 25v I usually replace them with 35v and use the same ufd's as the old cap. This is usually the fix for this problem, Hope this is helpful.

If you are DIY'er go to Display in Control Panel and reset to default, this might work. If not, try a RESTORE POINT roughly before condition started.

My SyncMaster 740n is stuck in power save mode. I have rebooted, unplugged power and vga chord...the thing was on and all of a sudden POOF it was black. The power light blinks every second or two.


zolio, Monitor most likely has "switch-mode-power-supply" problem!! click on blue highlighted "SyncMaster 740N" and read about similar BLACK SCREEN of DEATH failures and how to fix them!! Your monitor I suspect is no different than any other LCD with "cold-cathode-fluorescent-lamps" for backilghting that fail to light-up. You can even visit YOUTUBE for videos on fixing BSOD problems!! Also a ton of stuff here on FIXYA!!! Just read and follow some of the links!! you WILL find out about everything you DIDN'T know of HOW and WHY lcd monitors fail. And better still, LEARN how to do the repair work or contract out the work to a Technician or other monitor REFURBISHMENT depot. Have you tried SAMSUNG to do warranty work? If this response was of some help please rate on FIXYA . 12fixlouie

Syncmaster not showing any image even when it says it's on


If you know a little about electronics? You can open the unit up, find the power supply. Look at the tops of the caps. Are they bulgging on the top? If they are, they are bad. Sometimes there might be 4 to 6 caps that are bad. If the caps you are replacing are 16v replace them with 25v if 25v go to 35v, Always keep the same mfd rating. Some caps are under rated in these ;units. Make sure you don't get them in backwards, I found bad caps in my samsung 740, but this may or may not be the case with yours. Hope this is helpful.
