New Samsung monitor, Syncmaster 2043BWX randomly goes completely black for about one second and then flashes back on. I have a new replacement that is doing the same thing. My video card is Nvidia NX7300LE, I'm using the digital output.

Samsung syncmaster 172v Screen goes black after about one second. Comes back to normal after turned off, but goes black again in about one second. Rebooting computer has not fixed this.


Sorry it is like your monitor needs service. Electrolytic condensators in power supply need to be changed. Give it to an electronic shop, it is a job for a specialist.

Monitor will flash the display for a second then go black again.


Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Flashing power button on Samsung SyncMaster 920NW


Yes, More than likely the problem with the unit is blown capacitors on the power supply board, the flashing power light is a good indicator of this type of failure. Here is a link to a repair guide with pictures and videos showing how to open the unit and what to look for and replace to get it back going again.

Monitor goes blank after 3 seconds -Samsung SyncMaster 920NW


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.

> brand-new out-of-the-box

Presumably, it has a "warranty".

So, take it back to where you bought it, and demonstrate the problem to them, and make them repair/replace it, under warranty.
