At first the unplugging truck used to work for me then as it progressed I had to leave it unplugged for longer & linger periods of time til it got to the point I was unplugging for 2-3 day spans....

Hi, a couple weeks ago my UN65KS8500FXZA shut off and will no longer turn on (constantly powercycles before ever fully turning on). I have tried all of the troubleshooting tips in this thread and nothing will work. I am extremely disappointed in how quickly this premium priced device failed. This seems to be a pretty widespread issue with this TV model.

 

Samsung support, is there anything you can do to remedy this problem?

My issue is clearly a loose One Connect port on the back of the TV. If I apply light pressure, pushing into that port, the TV will stop its boot loop and come up fully. Once its up, it stays up. This is only slight annoying to me, but infuriating to my wife, as she is unable to get it just right and have the TV boot up when I'm not there. TV was barely out of warranty when this started. Massively frustrating. Why in the world is booting up dependent on the input connection? Now I may have to attempt repair myself, and risk bricking the TV.

I have the same model it's been doing the same thing too. I opened up another thread. Did you get it resolved? I'm so upset because it's only been one month since it got out of my amex warranty. Clearly this seems to be a product defect since so many of us are having the same issue. I hope Samsung is able to help us it's a great company. We didn't buy an expensive Samsung TV just so that it goes bad in 2 years Smiley Sad

Samsung is going to ask to? 

 

Disconnect one connect. 

Plug it directly into a wall socket 

Change remote batteries 

Make sure there aren't usb or external devices connected.

Unplug it for 15 minutes and try again. 

 

Etc etc 

None of that will work though. Clearly there's a bigger quality problem. I wish they would just tell us what the issue is so we can look into fixing it ourselves. Instead of having us set up a service request for which they take 200$ just to diagnose what's wrong with out TV.  Clearly they should have an idea since so many people are having the same issue.
