Samsung S34E790C – 34-Inch Curved WQHD Cinema Wide (3440 x 1440) Professional LED Monitor screen – Issues
I purchased a Samsung S34E790C – 34-Inch Curved WQHD Cinema Wide (3440 x 1440) Professional LED Monitor screen from Fry’s Electronic’s back in 2017. The same screen can be seen here:
I started having issues last year around June 2020. The screen would just turn off by itself and I had to unplug the power supply for 20 seconds and plug it back in. I use different combinations to turn on and off the screens. But it does not stay on for long. At first I was concerned about the internal parts being damaged. So I ended up putting it in storage for a long time and I was using a 42″ Cheap TV as my primary monitor. Last week, I was starting to get headaches because of the screen resolution on the TV and decided to take the leap and replace the power supply on the Samsung S34E790C screen. I purchased the power supply here (https://www.ebay.com/itm/AC-DC-Adapter-For-Samsung-SyncMaster-BN44-00794A-A10024-EPN-BN4400794A-A10024EPN/351934293871?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649).
I received the powers supply yesterday and it came with an adapter to fit the Samsung screen.
So far, it’s been close to a day and the screen has been working properly.
The original power supply that came with Samsung is Model # A10024_EPN 100W. I wasn’t sure that this would fix my issue with the screen, but I’m very happy with the results.
Hope this helps someone with the same issue that I am having. I literally went all over the place for the solution and I could not find it. I even contacted Samsung directly to repair the screen, but the price was more than I expected.
