    Samsung Syncmaster 740n nothing on screen

    Dear friends,

    I have a Samsung Sync master 740n that showed the led but nothing screen.

    During the troubleshooting I found out that three capacitors of 820mf 25v and one 3A pico fuse were bad.

    All the bad parts are been replaced but still the same, only the led light on.

    Please what next should I do?

      Check the BL_ON signal from the signal card to the power supply / inverter.
      Check the replacement fuse - it may have blown for the same reason the original one blew.

      For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

      Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

          Samsung SyncMaster 740n Phase Control Issue
          by vincentedel
          Hello,
          I'm having an issue with the Samsung 740n's phase control setting. When I use the automatic adjustment, it sets the value to around 54 (with a range of 0-100), and the picture looks clear and sharp. However, after some time—like after playing a game—the text starts to look blurry. When I auto-adjust again, it may increase the value to 80, and everything becomes sharp once more. Yet, after a while, whether it's a few hours or a day later, the same blurriness returns, and I have to adjust it again.

          I'm using the Samsung 740n monitor drivers instead of the default plug-and-play...

          Samsung UE55JU6800K half screen dark
          by Chrissygizmo
          Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
          I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

          samsung galaxy ao2s very temperamental after screen replaced
          by Chrissygizmo
          Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
          Ive eventually managed to get it on and working but it's very temperamental...

          The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...

          Samsung LH82QENELGC/EN Help needed - Static line on screen
          by Kiberge
          HI guys!

          I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
          I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊

          the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.


          This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...

          Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
          by Ryan.man
          Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

          My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

          This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...
