The solution that helped me requires some technical skill.
I separated the screen from the screen shell/cover and disconnected the display cable. Then I cleaned the connector using a pencil eraser and connected things back together. After that, I used a double-sided tape to attach the LED panel back to the screen shell. (I had to use special double-sided tape designed for laptop LCDs though.) It has been more than two weeks since the repair and I have not experienced any issues with the screen since.
Hi, I am having the exact same problem with Samsung Notebook 9 Pro. This device is only a few months old, yet the screen has randomly gone black. The power supply & AC adapter works fine. The battery seems to work. basically, it's like the PC went to sleep but will never wake up again. The PC worked perfectly prior to this, & the only thing recently that happened was "Samsung Update" which claims to install new drivers.
I have some electronics experience but the Samsung notebooks are very difficult to work on bc everything is soldered together & the battery is internal. I can tell that the LED panel is not lighting up, & I don't hear the fans coming on. When you close & open the laptop, nothing happens. The LED lights that indicate the charger are working though. it's green/ fully charged, then turns blue when I touch the power on button, but the screen doesn't come on & the PC doesn't boot. I've hooked it up to other monitors & Samsung TV as well, & none of those work.
What should be done to fix ASAP please? This is my primary work machine.
Thank you, this was resolved by the tech support resetting the PC so that it could boot up, & then he discovered it had crashed during update. He said it needed to fully run the Windows Update & Samsung Update to restore current versions of the drivers. Once all the updates were finished, the screen is no longer black & the keyboard & touch screen work fine now.
You are most welcome.
