Why Does My Samsung TV Keep Turning On and Off?

Samsung TV Won’t Connect To Wifi [ Causes & Solutions]

Before we get to the solutions, there are areas we need to focus on first and that is the causes or the factors that trigger such an issue. 

 

Below, we will highlight some of the most common offenders.

1. Power Supply Issues

 

An unstable power supply is commonly cited as one of the principal reasons for a Samsung TV to turn on and off continuously.

 

A damaged power outlet, power surges or a malfunctioning power strip can cause these problems. 

 

This translates to the fact that if the TV does not have a steady or constant power supply the device may go off and back on by itself.

Personal anecdote:

When my Samsung TV switched itself off and on without my intention, I thought there was possibly an internal problem. 

 

But then after examining the power supply, the power strip that I had was quite old and broken. With a different power strip, the problem was solved in a couple of minutes.

2. Overheating

 

Samsung TVs, like all other electronic devices, produce heat when they are in use. 

 

The television may go off for a while if the ventilation surrounding the TV is limited or its internal parts are too hot to operate. 

 

It is a common precautionary action taken in order to prolong the life of the TV set.

 

If the TV vents are clogged or there are high temperatures in the room, this can result in this particular occurrence of there being repeated turning off of the power. 

 

In some instances, the message “Overheating” may appear on the screen before the television’s power off.

3. Faulty HDMI Devices or External Inputs

 

Other devices connected to your TV may be causing your television to restart. 

 

These devices could include HDMI cables, portable electronics like gaming consoles, soundbars, or Curtis streaming devices. 

 

The reason could be the conflict of the TV with the connected devices. 

 

For example, certain HDMI ports may be defective or the device attached via an HDMI port might be transmitting contradictory signals to the TV.

Personal anecdote:

After connecting a gaming console with one of the TV HDMI ports, I experienced this particular issue as well. 

 

Every time I changed to gaming mode on the tv, the tv would keep switching on and off again and again. 

 

Unplugging the console from the HDMI connector and plugging it out from the other port resolved the issue. Sometimes, resetting the console or even a firmware update may help as well.

4. Software Bugs or Firmware Glitches

 

Errors in the schema or outdated software can cause troublesome activities on smart TVs. 

 

Smart TVs from Samsung are like all other smart devices that need to function well so they require software updates. 

 

When the tv system firmware is either old or corrupt, it shows instability which includes random freezing or continuous on-and-off cycles.

 

Firmware update is usually done by Samsung since the updates fix some bugs and enhance the TV quality. Therefore, one’s television should always be updated.

5. Faulty Remote Control

 

A remote control that hasn’t been well manufactured can in rare cases be the reason behind this. 

 

If the remote has broken buttons, or when the remote control fails to function properly, this could trigger the tv sending signals to itself to turn on and off, hence making it appear like the tv has malfunctioned.

 

Personal anecdote: 

A friend of mine had once experienced a Samsung TV that would turn itself on and off for no apparent reason and it was eventually found to be a result of a malfunctioning remote control which needed to be replaced. 

It turned out the volume control was pressed and caused the TV to get a signal constantly. After getting that remote control, the TV functioned perfectly.

6. Incompatible Apps or Settings

 

A dysfunctional application or incorrect settings may sometimes trigger a repetitive cycle of a TV turning on and off. 

 

For instance, if you have an auto-update feature that is switched on, or if there’s a bug with a particular application, it may cause the TV to automatically restart.

7. Internal Hardware Problems

 

Finally, the power cycle of the TV can also be due to internal hardware problems like a broken power supply board or an impaired capacitor. 

 

These are uncommon; however, they happen and particularly with older models.

How to Fix the Problem: Step-by-Step Solutions

With the problems out of the way, let us now look at how the issues can be resolved. 

 

Each remedy has a specific causative factor so you will only do what is appropriate to the problem you have.

Solution 1: Check the Power Supply

 

Continuously switching off will result whenever the TV is unable to receive stable power. Here is what you are supposed to do:

Inspect the Power Cord and Outlet: 

The power cord must be firmly connected to both the television set and the socket. If there is any tracing of the cord, it will have to be substituted with a fresh cord.

Use a Surge Protector: 

If power strips are needed, you might want to give connecting the TV to a wall outlet a shot. 

 

A damaged power strip may disturb the electricity supply and cause the TV to shut off. Otherwise, avoid surges with a surge protector.

Test the Outlet: 

Try connecting a lamp or another device that does not have problems to the same outlet. If it doesn’t work, then you could just try another outlet for your TV.

Check for Power Surges: 

If there are frequent power surges in your area, think about using surge protectors with high protection ratings (in joules). This can prevent the TV from experiencing problems in the future.

Solution 2: Fix Overheating Issues

 

If the problem is due to overheating, do the following:

Clear the Vents: 

Ensure that no pieces of furniture or any other objects obstruct the ventilation openings of the TV. Make sure that the space around the TV does not have an air blockage.

Reduce Room Temperature: 

You can use an air conditioner or fan to cool the room if it is very hot. Leaving the TV in room temperature greater than 80°F (27°C) puts the chances of the TV overheating.

Elevate the TV: 

Position the TV on a shelf or a wall mount so as to reduce the crowding of air around the unit.

Solution 3: Check Connected Devices

 

If some external devices like HDMI cables or some appliances cause the problem, do these ones:

Unplug All Devices: 

Remove all the external devices (gaming consoles, soundbars, Blu-ray players et cetera) attached to the TV. 

 

Now power on the TV and observe if the situation has given in..

Reconnect Devices One by One:

Reestablish connections to the device until it is clear which one causes discomfort to the user.

Reset Devices: 

As for the case with consoles or even streaming devices, reset these consoles or update their firmware to the latest version.

Solution 4: Update the Firmware

 

Addressing software bugs can be carried out as given below:

Check for Updates: 

From the TV settings select ‘support’ or ‘software update’. If there is an update, install it.

Manual Update: 

In case an update is not automatically detected by the TV, obtain a firmware file from Samsung support and copy this onto a USB flash drive and insert this into a TV.

Reset the TV:  

In the event that the update does not succeed in correcting the problem, then one can consider returning the TV to factory state. 

 

Factory resets help in removing any errant settings or applications that may have infected other areas of the device.

Solution 5: Test or Replace the Remote Control

 

In instances when the remote itself is the problem.

Test the Remote: 

Take the batteries out from the remote and check whether the TV still turns on or off with the remote. If turning on or off ceases, then the remote is the probable cause.

Replace the Remote:

If it is determined that the remote does indeed malfunction, then a replacement must be secured. Where possible, a universal remote control may be applied.

Solution 6: Adjust Settings or Delete Faulty Apps

 

Should the problem be with a certain application or a specific setting, it can be solved as follows:

Uninstall Problematic Apps: 

Go to the settings of the television and delete the programs you suspect are problematic.

Reset TV Settings: 

You can try a factory reset if there were any changes made to the settings that need to be removed in order to fix the problem.

Solution 7: Contact Samsung Support

 

In case someone does not find any of the above solutions applicable and suspects hardware issues, it is wise to reach out to Samsung support. 

 

It is possible that a malfunctioning power board or some other internal complication is involved, and one may need to seek professional aid for definitive diagnosis and treatment.
