    Re: Samsung syncmaster 205bw

    Same problem...
    Blue light all time, without any response on click any button and nothing displaying on the screen.
    Caps are okay, not swollen. ¿What can I do?

    Dixie, Behemot, juggernaut... Anyone that had the same issue, have you solved that?

        So I'm having the same troubles, solid blue on the power light, no display or response to buttons. My computer does recognize it as a display when it's plugged in. I haven't switched out the capacitors, but I'm not seeing any bulging, and the earlier posts that say they switched and saw no change worry me. I've attached the pictures, any thoughts on a move forward is mighty appreciated. This is my first shot at fixing a monitor, hoping to get it working...

          Can you see image with flashlight?

          Lately the price of generic power supplies with inverters is dropping so there is a possibility of using universal board if the repair fails.

              That's with display connected to computer and all set up right?

                Yep, fully reassembled and plugged in. Computer recognized two screens, nothing on the monitor with or without flashlight. Had a bit of a misstep forgetting to plug the display ribbon cable back in, thankfully noticed that the second time around

                  If you still cannot see anything than possibly the signal board is bad as long as not only the backlight does not work but also there is no image at all.

                    Check that the PSU is supplying all the rails it should be, and they are correct. Check any regulators on the logic board and make sure they are working too

                        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...
