  2. Select  Settings on the TV.

The Samsung TV will automatically reboot itself and set itself back to the factory settings.

Your Samsung TV Is Overheating

If the Samsung TV is set up in a very enclosed space without any fresh air moving or the ambient temperature is very high, the TV may overheat.

It is also possible that the Samsung TV air vents have become blocked with dust or obstructed by something covering them.

To protect itself, the Samsung TV is designed to switch off and prevent any damage if this happens. 

Follow the next steps.

  1. Switch the Samsung TV off and disconnect it from the wall plug. 
  2. Using a dry microfiber cloth, clean all of the dust off the back of the Samsung TV. 
  3. Clear anything out from the back of the TV which may be blocking it and the vents.
  4. Try operating the TV outside of its normal position with clear flowing air.
  5. Switch the Samsung TV back on and check if this makes a difference.

Power Supply Issues

If the power supply to the Samsung TV is faulty, this will cause it to switch off regularly.

If the current is not strong enough, the Samsung TV will switch off.

To check the power supply, follow the next steps.

  1. Carefully check the power lead, ensure that the plugs’ cable connections have not become disconnected, and check the cable for obvious damage.
  2. If the cable has become compromised, it is better to replace rather than try and fix it. 
  3. If the TV still doesn’t switch on, check that there is current at the wall socket.
  4. The easiest way to check for power is to plug in an appliance you know is working and see if it switches on. If not, the problem is not with the Samsung TV. 

If the wall socket is working and the Samsung TV is still not operating, move to the next step.

The Samsung TV Has A Defective Motherboard

If the above steps don’t produce the desired results, the problem may be more serious.

If the motherboard has a fault, the symptoms may be that it switches off regularly.

The motherboard is the central switching point where the power cord connects, and the current is distributed to the various components as required.

If the motherboard is damaged, it is possible to remove and install it yourself; however, it may be safer and, in the long run, cheaper to have a professional technician do the work.

Feeling adventurous? Then take the back off the TV and check if any of the capacitors are swollen. It signals that they have been damaged. The cause could have been an electrical surge or even that your home has been hit by lightning.

Something Wrong With Your Samsung Remote

It may seem a little condescending to indicate a problem with the Samsung remote; however, if it is not transmitting a signal to the TV, the TV won’t be working properly.

Even if the indicator light flashes when you press a button, it is no guarantee that a sufficiently strong signal is being sent to the TV.

To ensure there is no problem, replace the remote batteries and see if that makes a difference.


If your Samsung TV doesn’t switch on or switch off after a short time, it may have an incorrect setting or flat batteries in your remote. Before dismantling the Samsung TV, follow the steps in this article and see if they make a difference.

If none of these actions work, it may be time to call a professional and have the TV repaired.
