If your Samsung TV won’t turn off, a likely cause for this is due to the remote being low on battery. Because TV remote batteries last a very long time, it is easy to forget about them, and it catches people off guard when it is time for new batteries.

The second reason why the TV isn’t powering off via the remote is that it was powered directly from the TV, resulting in the television not responding to the remote. A solution that should solve this issue is to unplug the power cord for at least 60 seconds, plug the power cord back in, and power it back on via the remote – assuming it has functioning batteries. 

You may also need to resync your remote to the TV by holding the “Return” and “Extra” buttons at the same time while the TV is powered on.

  2. Unplug the HDMI and power cables.
  3. Wait 15 seconds.
  4. Plug HDMI and power cable back in. You should feel both connectors clicking in place.
