My Samsung TV ( UN43RU7100FXZA ) keeps turning off and on. I tried unplugging it from the power source multiple times, and it keeps doing the same thing. As soon as I touch any button on the remote, it shuts itself off. There's no chance even to check if I need an update, and also, if I did, it probably wouldn't stay on long enough to perform the update.
I purchased this TV in November 2019, so it is only a few months old. I was watching TV and it just randomly started happening. I have nothing connected to it other than a brand new FireStick. I even tried unplugging that to see if that was giving me issues but no luck.
If the unit is turning on and off by itself try the following:

I'm just wondering if a solution was found to this problem. My old TV was doing the same thing...i just thought it was time to get a new TV. I bought a brand new UHD TV yesterday, and am having the same issues. I got through the set up process via phone app...the second I hit a button on the remote, the TV shuts off.
