Same problem here. Out of warranty, but I still submitted a service ticket. Given the number of people with the exact same problem, this should be covered by Samsung, IMO.

The problem with my TV turning off and on has been a constant annoyance for many months now. I tried every possible solution suggested here. Nothing has made a difference. But I still haven’t thrown in the towel just yet. Hopefully if we all share our experiences, we can come up with the solution. I noticed something I can’t explain about these shutoffs that might be a clue in figuring this thing out. Ok, so I tape a certain program and have a bunch of the episodes stored on my DVR. At the end of every episode, PRECISELY after the announcer says ‘’And on the next show...’’, the TV turns off, like CLOCKWORK. EVERY time in that EXACT spot. EVERY episode. It has nothing to do with the timer because I can rewind it again to the very spot it turned off and it will happen again. Really weird, right? Usually the shutoffs are completely random and happen only a few minutes or even seconds after the TV is first turned on. Other times, it could be ok for a good half hour. But then on certain occasions, if we are watching something On Demand, it will turn off 5 or 6 times in succession and the only way out of it is to fast forward past that scene. This might seem to indicate that the problem has something to do with the graphics? Could this be a clue somehow to our great mystery? Just thought I’d mention it. Anyone else have this happening to them too? Please share on this thread.
Hi, either the remote control is running low on batteries, failing that, unplug for a few minutes from main power, failing that, have you got any other remote control devices around? My LED lights remote control kept switching my tv off and on again
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....
After watching videos from many who suffer same problem, I took off the back and checked all capacitors and found one that wasn’t working but can’t find it anywhere not even on the SAMWHA website
