I have a Samsung UN50KU6300 with the smaller remote. Last night I noticed the on/off button stopped working, but the Comcast TV smart remote worked so I shut it off with that. This morning I walked in the room and the remote was sitting on the side table blinking red like someone was holding down a button. I touched a button and the red light went out. I used it to turn the TV on, sat down and within 15-seconds the TV paused and I saw the red remote light was back constantly blinking. I hit a button and it went out, but came back on constantly within 10 seconds or so. After repeating this a few times I got a screen on the TV with the model number telling me to contact Samsung.
So I took the batteries out, and the TV works fine with the Comcast TV remote (just limited to TV with no smart TV functions like Netflix and YouTube.). If I put the batteries in, same thing - works for a moment normally and then the red light is on constantly, repeat until the TV flashes the contact support screen.
I tried resetting the remote, repairing it, same thing. I am guessing the remote has some sort of internal fault, but wanted to check here first.
You have pretty much completed all of the troubleshooting possible. I would agree with the internal fault diagnosis. If you would like to replace the remote, I recommend reaching out to https://www.samsungparts.com or J&J Parts International at 800-627-4368.

After a bit of google-sluething I came across a Samsung tech document (https://www.samsung.com/us/support/troubleshooting/TSG01202543/#unable-to-control-the-tv-with-the-re...) that outlined exactly how to (correctly) reset a Samsung One remote. The first solution I found, to take the batteries out and hold down the power button while replacing the batteries, is not correct. I did that, it re-linked with the TV and then continued its "always on" pattern.
The correct procedure to reset a malfunctioning remote is to take the batteries out and then hold the power button down for at least 8 seconds (I went 20-seconds to be on the safe side). Then release the button, reinsert the batteries, and then hold down the play/pause and back buttons to initiate the re-link process.
I did that and I now have a happy, normally functioning remote control again!
Just in time too, as the cheap Amazon replacement arrived the next day, and was DOA. I'd rather have bought the OEM replacement for $40 but it states it takes 4 to 6 weeks to ship.
Another note, the samsung remote Ap for the iphone works the TV just like the remote and worked perfectly while I searched for a better solution.
I have a remote control that, after I turn off the TV, will turn on the TV after 30 seconds. I know the remote is turning on the TV because I watch the remote and it blinks rapidly, about 7-8 rapid double blinks. The TV will then come back on. This happens after about every 10 uses of the TV. The other 9 times, the remote will do a quick double blink after 30 seconds of turning off the TV, but the TV will not turn on. But every 10th, or so time, the remote will blinks a lot and turn on the TV. This cannot be normal.
Yes, I recently put in new batteries. I also held down the power button for a while and also the play and back button when the batteries were out. I went through troubleshooting with a Samsung expert whereas I unplugged all connections to the TV, unplugged the TV, confirmed Anynet+ is disabled. But it seems the TV is not the issue, but rather the remote is the culprit.
