Question about Samsung SyncMaster 740N 17" LCD Monitor

1 Answer

The samsung LCD monitor(740N) was black out, but if you look "very closely" you will notice that the monitor is working but you can't see the output. Its like there's a problem on the monitors backlight or light/bulb inside that support the monitors output. Looking forward for your response.

The problem will either be with the backlight or the inverter for it. The only way to be sure will be to take it apart and check whether or not the inverter is putting out the correct voltage.

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

How do I open a samsung 740N LCD Monitor


Lift the front frame. You must try to lift it from the inner side using your fingers (no tools , you may scratch the lcd panel). A little force is necessary especially at the corners. Once you lift the panel from all four sides then the corners will come out.

Note: A common problem with this monitor is the psu. A small number of capacitors fails. You will notice 3 electrolytic capacitors have been deformed and if there is no power you will find a small 3A fuse (looks like a resistor) blown.
