SOURCE: Samsung LCD Monitor SyncMaster 203B

Hi this is the way how to examine what's wrong with your LCD monitors. After you turned it on and the screen blacked out or stopped working, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

SOURCE: SyncMaster 203B (Black) LCD Monitor: Monitor will not stay on (Samsung Syncmaster 203B)...

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

If not into lcd monitor "tear-down" and repair, just trade in for new. May only be 1 poorly soldered lead of some component on switch-mode supply board/ inverter board. Check for swollen electrolytic filter capacitors on same board. 12fixlouie

Welcome to Fixya.

Please try the following steps to resolve this problem - this same procedure worked for my colleague :
  • Power off printer
  • Hold down STOP/RESET button then Press and Hold down Power button
  • Keep Power button down and Release STOP/RESET button
  • Push STOP/RESET button twice
  • let go of power button
  • Wait 20-30 seconds - my display shows "canon Idle"
  • Then Push STOP/RESET button four times
  • Push Power button twice
  • Power off (shut printer down)
  • Wait for at least 5 seconds and power it back on
This should do the trick and will get you printing again in no time.

Thanks for using Fixya.

Monitor won't stay turned on. You push the on button and it flicks on and then immediately off. Help!


The possible problem of your monitor is may be cold solder, bloated elec. capacitor or defective lcd panel. If you found that bloated capacitor replace it and resolder all pins of inverter area. Defective lcd panel could cause of display flicks then immediately off.

mcdevito75 here, You can try to hold the button in for 3--5 seconds see if that helps. Switch could be bad, bring the monitor to Staples or computer repair for test.
