UN65KU6290F TV Stopped Working

My Samsung TV just stopped working mid-show. The screen went black and appears as if there is no power to the TV. It was in a power strip with the cable box which is still working. Tried a different outlet to make sure - TV acts as if it has no power: black screen, no lights, just dead.


I think I bought it in 2018 so its not old and is not used very much. This is the first issue with the TV since we bought it.

Does the remote light up? 

Unplug the TV for 30 seconds.

  • Unplug the TV from the wall outlet or surge protector for 30 seconds, and then plug it back in

Try to update the software.

  • In some cases, a software update can correct the problem. There is a risk, however. If the TV turns off during the software update, it could damage the TV. Updates can take up to 30 minutes depending on network speed, so if the TV is not turning off too frequently, try updating the software.

Disable the Power On with Mobile option.

  • TVs that can connect to SmartThings can be turned on using compatible devices, sometimes automatically. However, if abnormal "power on" signals are sent through the wireless network, they will trigger this function and make the TV turn on.
  • If you do not want this function, navigate to Settings > General > Network > Expert Settings > Power On with Mobile, and turn the setting off.
