Re: Samsung S24D390HL flashing on and off - wrong power supply ?

I'm here a little late, but I hope this works for the future people.
I have the same issue with the same monitor, I fully opened it and looks like the problem are the backlights. One of them don't turns on and maybe this makes that the main board detect and incorrect current and protect itself.
I bought a replacement, when I have it in my hands I will change and tell all you if it worked....
