    Samsung SyncMaster 223BW

    Hi all,

    Have a little problem with a 223BW samsung ...

    Have changed all 5 820uF capacitors,the 330uF,and the big one 100uF/400V (with 150uF/400V)

    The problem is the monitor turns off after 2,4,5,10 minutes (no rule when) ...

    The power led is on,but no picture,after pressing the power button off/on the monitor works (for 2,3,6,9 minutes) ...







    Example : the autoadjust pressed,and after 5-10 sec screen goes off
    the autoadjust pressed, and after 30 sec the screen goes off

    the power button remains on (blue)


    thx

    Check with a lamp if the image is still present.
    Low the brightness at minimum in order to see if it stays on for more time.

        Probably the inverter transformer.

            Hello,
            As i can see you are using windows 7 and maybe this wont help you but i will say.

            I had similiar problem,first i changed inverter transformer because it was turning monitor off after 5 sec, after that monitor was working same as yours 2,4,5,10 minutes.

            I have found out that was problem with windows 10 and graphic drivers because i had one monitor and just switched on another.

              by soopacrucial
              Hi folks,

              I'm new here and was wondering whether you might be kind enough to give me some advice on troubleshooting the following problem:

              Quite a few years ago now, a couple of years from new, my Samsung Syncmaster 740BF LCD monitor starting playing up by making a buzzing noise and then the display would go blank. I seem to remember the blue power led would also go off when this happened but that I'm not 100% sure of. By pressing the power button I do remember I could at first get it working again but eventually the problem would come back. At the time I had read about...
