My samsung syncmaster 920nw picuture goes blank after a period of a couple of minutes. If I turn the power off and then back on the picture re-appears but goes off again. It is not he pc since it works...


If you get a flashing screen which show your screen for few minutes and then goes blank it may be an issue with the Monitor.

Try to restart the computer and go to BIOS setup screen. If you experience the same issue in BIOS then the monitor needs a repair or replacement for sure.

The monitor powers up and the analog icon blinks on and off and nothing else happens...no colors...when connected to computer.. The images show for a few seconds and goes blank...turn monitor off and on...


Most common failures 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

Gateway Monitor goes blank after a few seconds after startup.


Sounds like the inverter is broken or have a short circuit. This is a common failure on TFT displays.

Here is a website explaining this kind of failure:

Screen Goes Blank


Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

Monitor goes blank after first few seconds of turning it on...


There's an internal electronic part/s of your monitor that are cold soldered / defective. I suggest to bring the unit to an authorized service to properly diagnosed & fix the problem. best regards

Screen goes blank after a few seconds


Hi ,
The monitor flicker problem. The monitor when turn on will display image for couple of second then turn black. The monitor status led is still green. This will happen each time it is turn on. The symptom at appear to come from the inverter board.
