Model # UN65F6300AFXZA This is my recent experience. May or may not work for others. Believe it or not, it has something to do with the remote. It doesn't make any sense to me, but through various tests, I was able to isolate it to the remote. What works Step 1: Make sure the tv is in powered off mode. Simply unplugging it when it keeps turning off and on will not work. If the TV turns on automatically after you plug it back in, then you did it incorrectly. Step 2: Unplug the TV for 10-15 minutes. Step 3: Remove batteries from remote Step 4: Plug TV back in. Step 5: Turn TV back on with controls on the TV itself. If the TV unit is now stable, then the remote was the issue. Like I said, doesn't make sense to me why the remote would impact the unit even if it is not directed at the remote sensor. I stress again that this is what worked in my situation. Your mileage may vary. I haven't been brave enough yet to test if the tv will work normally with new batteries in the remote. I will conduct this test in the next couple of days and update all of you. Right now, this is my only tv and don't want to risk it until I get my new tv mounted and running. Edited to Update: Finally had a chance to test if the remote itself was malfunctioning or if it was a low battery situation. Verdict is that the remote is malfunctioning. Inserted fresh batteries in the remote and the TV resumed its on and off cycle. Following the steps outlined above restabilized the TV. Edit #2: After a month or two of peace, my TV suffered a relapse. Disabling Anynet+ has resolved the issue for now. There is an outside chance that using the HDMI 3 input might also trigger this death cycle.
