I also just finished a chat with Samsung support, and they set me  up with a free mail-in repair for my BD-J5900. ... View more

@SamsungSabrina, first, thank you, I suppose, for being SOMEONE who represents Samsung and also has responded to this, to some degree (however minimal), after utter SILENCE from Samsung for the last few days.   Secondly, I must be missing something, how is this a "solution"??   How will the "real solution" be implemented/communicated to all customers? ...

Here's probably the largest thread on it so far: https://us.community.samsung.com/t5/Home-Theater/Blu-ray-player-BD-JM57C-keeps-cycling-on-off-whenever-plugged-in/td-p/1278935 ... View more

In the larger thread that is referenced above, it would seem as though Samsung is aware of this issue, even if not all tech. support people are. Based on the recent conversations quite a few people have claimed to have had with Samsung (I've been checking out the most recent comments), within the last 24 hours or so, they're aware of the issue and working to fix it. Hopefully this is true. ... View more

Same here. I'm (somewhat) relieved to hear I'm not the only one! I was about ready to smash my BD-J5900 last night. Exact same issues people are describing. My J5900 has worked perfectly fine up til now.   Starting on the evening of 06/18/2020, I turned on my player (there was no disk inside), it started going through this on/off/on/off cycle, right away. It powers on for a few seconds, the home screen shows briefly, and then it switches off, then on, then off, etc. I've tried unplugging for 10 minutes, pressing down the eject, or power button, etc. to reset, and nothing is working. Connected via Ethernet.   I hope Samsung finds a satisfactory solution quickly. ...

Hmm, interesting. Glad you still have at least ONE working. My BD-J5900 has always been wired (is it possible, despite being wired, that it goes wireless sometimes?), and is still having this issue cycling on and off.   Hopefully Samsung comes up with a satisfactory solution to all of this. ...
