Re: Samsung QLED TV turning off and on by itself I have read all 37 pages of comments about this issue on this site. I have the 2019 Q80R model and am having this same issue. I have unplugged the tv, the cable box, and my Sonos beam soundbar. Waited 15 minutes and replugged everything. It worked for an hour and I checked to make sure the software was the latest and that the automatic update feature was on. It was all good. Then it started turning on and off again. After reading all the comments, I started trying every solution offered. The Q80R does not have the one connect box so that isn't the source of my problem. I have taken the batteries out of my remote and it did not solve my issue. I replaced the batteries with new ones and reset the remote. That did not work. I turned off the Anynet+ HDMI-CEC setting but then my Sonos sound system doesn't work. So I turned it back on. Then I decided to just use the tv speakers and see if it worked. It still did the same thing. I just turned it back on since it did not solve my issue. This tv is not a year old yet. I registered the tv using the code on the box and set up a Samsung account, but they want the reciept for proof of warranty. Unfortunately I can not find the receipt. Therefore I can't prove it is under warranty. This is the most frustrating experience! 37 pages of the same issue from so many and still no solution from Samsung. I will never have anything from Samsung again.
